Summer is quickly approaching the Dallas/Fort Worth area and the summer heat is no joke for your car. Keeping your cars radiators and cooling system in proper working order is super important to ensure you’re not left stranded in the Texas Heat with a car that’s overheating.  At AAMCO of Keller we aim to be your locally trusted auto repair experts to help keep you and your family on the road safely this summer.  Here is some important info to learn about your car radiator and cooling system.

The car radiator is one of the most misunderstood automotive components. This may be because a car radiator works so differently from a home radiator. The one in your home works essentially to warm up the immediate surroundings—but the one in your car does something a little different.

The Car Engine Cooling System

It’s actually an invaluable part of your engine cooling system. Of course, your engine both burns fuel and creates friction in order to give your car the juice it needs, and that causes a great deal of heat to build up. That heat needs to be diverted away from the engine, or else it could cause tremendous damage. The pistons in the engine would seize up and snap in two, and the engine would be broken down completely. That’s why engines have built-in, multi-part cooling systems. This includes an exhaust system, through which heat can escape. It also includes oil, which lubricates the engine parts and reduces the amount of friction. Even so, engines can get hot pretty quickly—and once they hit a certain temperature, the rest of the cooling system kicks in.

A typical 4 cylinder vehicle cruising along the highway at around 50 miles per hour,  will produce 4000 controlled explosions per minute inside the engine as the spark plugs ignite the fuel in each cylinder to propel the vehicle down the road.  Obviously, these explosions produce an enormous amount of heat and, if not controlled, will destroy an engine in a matter of minutes.  Controlling these high temperatures is the job of the cooling system. The modern cooling system has not changed much from the cooling systems in the model T back in the ’20s.  Oh sure, it has become infinitely more reliable and efficient at doing its job, but the basic cooling system still consists of liquid coolant being circulated through the engine, then out to the radiator to be cooled by the air stream coming through the front grill of the vehicle. Today’s cooling system must maintain the engine at a constant temperature whether the outside air temperature is 110 degrees Fahrenheit or 10 below zero.  If the engine temperature is too low, fuel economy will suffer and emissions will rise.  If the temperature is allowed to get too hot for too long, the engine will self-destruct from overheating.

What Happens When Your Car Radiator Kicks In

There are actually two types of cooling systems found on motor vehicles:  Liquid cooled and Air cooled.  Air cooled engines are found on a few older cars, like the original Volkswagen Beetle, the Chevrolet Corvair and a few others.  Many modern motorcycles still use air cooling, but for the most part, automobiles and trucks use liquid cooled systems and that is what this article will concentrate on.

The cooling system is made up of the passages inside the engine block and heads, a  water pump to circulate the coolant, a thermostat to control the temperature of the coolant, a radiator to cool the coolant, a radiator cap to control the pressure in the system, and some plumbing consisting of interconnecting hoses to transfer the coolant from the engine to radiator and also to the car’s heater system where hot coolant is used to warm up the vehicle’s interior on a cold day.

A cooling system works by sending a liquid coolant through passages in the engine block and heads.  As the coolant flows through these passages, it picks up heat from the engine.  The heated fluid then makes its way through a rubber hose to the radiator in the front of the car.  As it flows through the thin tubes in the radiator, the hot liquid is cooled by the air stream entering the engine compartment from the grill in front of the car.  Once the fluid is cooled, it returns to the engine to absorb more heat.  The water pump has the job of keeping the fluid moving through this system of plumbing and hidden passages.

How the Car Radiator Works

  • A thermostat at the front of the engine detects when the engine reaches an unacceptable temperature. This triggers the release of water and coolant—both of which are held in the radiator.
  • This liquid combination picks up the heat generated by engine friction and burned fuel. It is then sent back into the radiator itself. The surface area is ample enough to let the coolant cool. Additionally, a fan positioned near it helps cool the coolant further.
  • Air from outside the car is brought in through vents, providing further cooling power. The coolant sufficiently cooled down, can then be sent back into the engine to pick up more heat.

What Happens When a Car Radiator Cooling System Stops Working Properly

The long and short of it is that your radiator plays a vital role in removing heat from your engine—thereby ensuring the engine can function properly, without risk of sudden breakdown. Over time, of course, various issues can prevent the cooling system from working properly. One common issue is that the thermostat, from which the coolant is released into the engine, becomes clogged and no longer opens. This is a significant problem: It means the engine can overheat and ultimately break down if you don’t have the problem corrected right away. An even more common reason for cooling system breakdown is a leak; leaks can cause coolant levels to become too low, which means there is not enough coolant to pick up the heat and remove it properly.

Certainly, if you notice fluid under your parked car and suspect a leak, it’s important to have the vehicle inspected and serviced right away. These problems can be serious, but spotting them quickly can lead to a more straightforward solution.

Is Your Car Radiator In Need of a Radiator Flush?

Anti-freeze, otherwise known as coolant, is the engine’s temperature-regulator. If you’ve ever had your engine overheat, you know how important it is to have the right amount of coolant. Think of your engine as producing a series of tiny explosions. The coolant is the fluid that keeps those explosions burning at the right temperature. The coolant keeps the engine warm in a brutal winter and cool during a blazing summer.

At AAMCO of Keller we recommend as a general guideline to flush the car radiator anti-freeze once a year. This removes any rust or scale deposits and keeps coolant from becoming acidic. Acidic anti-freeze eventually wears down the very parts the cooling system intends to protect.

What are the Benefits of a Car Radiator Coolant Flush?

  • Old anti-freeze eventually loses its anti-corrosive properties, which allows for debris to build up in the cooling system. A coolant flush removes these rust and scale deposits. It’s important to get rid of contaminants because they can cause overheating and damage your entire cooling system.
  • Fresh coolant contains additives which lubricate and can extend the life of your cooling system. These additives also help prevent rust from building up, which allows the cooling system to operate more efficiently.
  • Bring your car into AAMCO of Keller Automotive for a coolant flush and we’ll offer a free courtesy inspection. During this comprehensive evaluation, we check the entire cooling system – including the thermostat, radiator, water pump, hoses and belts.
  • A coolant flush prevents the old anti-freeze from becoming acidic. Once coolant becomes acidic, it starts to eat away at the water pump, rubber hoses and aluminum components of the engine.

Overheating is one of the most common contributors to mechanical breakdowns for many car owners in the North Texas area. Overheating can cause severe damage to the engine and transmission. The expert mechanics at AAMCO of Keller are here to keep your radiator, fluids and car cooling system in the best condition to keep you and your vehicle safely on the road.

At AAMCO of Keller we’re your local transmission experts for more than 50 years with a nationwide warranty. Many of our customers that are facing Transmission issues also experience drivetrains with problems.  A drivetrain may be the least understood part of a vehicle. This is due to several factors, including the fact that the term “drivetrain” is often used interchangeably with powertrain and driveline. The drivetrain includes the transmission, the driveshaft, the axles, and the wheels. Simply put, it works in conjunction with the engine to move the wheels. The drivetrain system is an essential component of a vehicle and the transmission is an integral part of the drivetrain.’

What are the common types of Drivetrains?

AWD – All Wheel Drive

The all-wheel drivetrain system has fluid-filled differentials and advanced electronics enabling the engine to send power to all four wheels. This provides a vast and highly improved capability for driving on wet or slippery roads. Examples of vehicles with AWD include the Ford Fusion, Nissan Rogue, BMW 3-Series, Honda CR-V and Audi A4.

RWD – Rear Wheel Drive

With rear-wheel drive, all of the engine’s power is sent to the back two wheels. Opposite of cars with FWD, a car with RWD is being pushed down the road. This does not work well in areas with icy winters because the level of traction is low. Despite this, RWD provides balance and offers superior braking and handling. Common RWD vehicles in Texas include the Ford Mustang, Lexus IS, Chevrolet Camaro and the BMW 5-Series. In rear-wheel drivetrain arrangements, power is transferred to the rear wheels to move the car. It’s the drivetrain arrangement that’s been around the longest and is still used today on many cars and trucks.

FWD – Front Wheel Drive

A car or truck with front-wheel drive has all of the engine’s power being sent to the two front wheels, so the drivetrain is basically pulling the car down the road. This serves to give the car more traction, providing stability, predictability and dependability when the roads get a little icy. Popular FWD vehicles include the Honda Civic, Volkswagen Golf, Mini Cooper, Toyota Corolla and the Honda Accord.

Front-wheel drivetrains have the same basic set-up as rear-wheel drivetrains, but the parts are a bit different:

Transaxle – Instead of a transmission, most front-wheel drivetrains have a transaxle. A transaxle combines the transmission and differential into one single unit. If you have a front-wheel drive car and you want to earn Car Guy bonus points, don’t refer to your transmission as a transmission, but as a transaxle.

While most cars that use transaxles mount them right next to the engine, some sports cars use transaxles on rear-wheel drive trains for even weight distribution.

Half-shaft- Because all the components of the drivetrain are in the front of the car, front-wheel drive vehicles don’t need long drive shafts to transfer torque to the wheels. Instead, a half-shaft connects from the transaxle to the wheel assembly.

In place of U-joints, half-shafts connect the transaxle and the wheel assembly with constant velocity joints, or CV-joints. CV-joints use a ball bearing mechanism to reduce friction and allow for the more complex wheel movements used in front-wheel drive cars — remember, front-wheel drive cars not only have to move the car forward, but also steer it left and right.

4WD – 4 Wheel Drive

The four-wheel drivetrain is similar to AWD in that the engine’s power is sent to all four wheels. However, 4WD is typically more robust because it’s designed to handle off-road driving. Some of the most common 4WD vehicles in Texas include the Range Rover, Ford F-150, Ford f-250.

The Drivetrain & Transmission

The drivetrain and the transmission are actually two very different concepts. The main function of the transmission is similar to the chain on a bicycle: it keeps the engine turning in time with the wheels, regardless of what gear the vehicle is in. The drivetrain represents everything that is behind the transmission involved in propelling the vehicle. The main function of the drivetrain is basically to convey power from the vehicle’s engine, through the transmission to the drive wheels on the vehicle to control the amount of torque. “Torque” is turning or twisting force.

What are the Parts of a Drivetrain?

The drivetrain is comprised of a collection of components in a vehicle that transfer power from the transmission to the wheels/ drive it forward. These components include the driveshaft, CV joints, the differential, the axle shafts and the U-joints.

Driveshaft – is a long tube of steel that is linked to a car’s transmission at one end and the wheels at the other. It transfers the mechanical power from the transmission to the other components of the vehicle.

U-Joint, or Universal Joint – is a flexible pivot point that transmits power allowing for varying angles of the driveshaft.

CV Joints, or Constant-Velocity Joints – are part of the driveshaft. These joints are designed to be able to bend in any direction while continuing to turn the drive wheels at a constant velocity.

The differential is where the power makes its last stop before spinning the wheels.

Axle Shafts – are a single rotating shaft, on either side of the differential, which delivers power from the final drive assembly to the drive wheels.

Technicians sometimes refer to driveline, drivetrain and powertrain interchangeably when referring to the drivetrain system of an automobile. This can cause confusion, but in essence, all of these terms describe the same system within the vehicle.

Proper yearly auto maintenance should always include insuring that your headlights, taillights, turn signals and parking lots are always working effectively. Many customers come to AAMCO of Keller for a yearly car maintenance check-up and find out that they may have a headlight out. While replacing the vehicles headlights with the factory recommended bulb is always the best option, many customers also wonder about XID or Blue Headlights as a replacement option.

What are Blue Headlights?

People commonly describe HID or Xenon headlights as “Blue Headlights”.  They are usually known as one of two things: other xenon headlights, or high-intensity discharge lights, or HID for short. These lights are known to produce an incredibly intense blue light when compared to halogen bulbs, and they give off minimal heat.  In order to produce HID lights, you need a lot of power right away to produce the first burst of light emitting from the headlights. Once the lights have fully been turned on and are at their brightest, they require less energy to maintain for an extended period of time, so they actually save you in power over time. They have a long lifespan, but they do cost more money up front to pay for them. The blue light mixes with a white light and emits such a bright light that it can be harmful to other drivers on the road. Many drivers actually despise xenon headlights on the road, especially at night as they can cause accidents due to their brightness.

Are Xenon or LED Blue Headlights better than traditional Halogen Headlights?

LEDs are the most recent innovation in headlight technology. Instead of gas and filaments, LEDs rely on small diodes that produce light when electric current excites their electrons. They need a low amount of power to work but do produce a significant amount of heat on the diode. This requires heat control systems at the bottom of the headlight and near other car components. If this system fails, not just the light, but other electronics could be affected. Xenon bulbs have a long lifespan and emit little heat, but they cost more than halogen bulbs.  Xenon lights, also known as high-intensity discharge (HID) lights, produce a brighter light than halogen bulbs and with far less heat. The blue-white light emitted by xenon bulbs is so bright, it has been known to “blind” other drivers. These headlights require a large amount of power at the outset to produce their first burst of light, but once fully operational, they require much less energy to maintain constant brightness. Traditional Halogen Headlight Bulbs still rank highest as the most common headlight on the market, but several alternatives, including xenon-based and light-emitting diode (LED) headlights, are growing in popularity.

Are Blue Headlights Illegal in Texas?

The most common question from AAMCO of Keller customers about Blue Headlights is are they illegal in Texas. The short answer is it depends on a few factors.  Any headlight bulb of the vehicle must be white or shades of yellow and amber; this is not only a Texas standard, but a federal one (according to 49 Code of Federal Regulations Section 571.108).

According to the Texas Department of Public Safety, any colored bulbs or headlamps must have the Department of Transportation or appropriate Society of Automotive Engineers stamp of compliance on them; there are currently no DOT-approved red or blue bulbs. Red and blue bulbs resemble the lights used by emergency and law enforcement vehicles, making them confusing or distracting for officers and other drivers.  So HID, Xenon or Blue Headlights sold by a reputable dealer or auto store can be used in Texas as longs as the Blue Headlights carry the appropriate DOT stamp of approval.

If you headlights are currently out or your car is in need of a yearly check-up call the experts at AAMCO of Keller for a full diagnostic checkup at (817)-431-0009. Click here to schedule your appointment online at AAMCO of Keller, Texas.

The summer is quickly approaching for DFW Texas and with the increase in temperatures comes the need for a reliable Air Conditioning system for your car. When the heat starts to approach North Texas many drivers find their A/C isn’t cooling properly. The expert mechanics at AAMCO Of Keller are here to provide some insight into some of the most common problems we see for drivers in the Keller and Fort Worth area facing air conditioning issues with their vehicle.

Reason #1: Your Vehicles AC Fan has Stopped Working

There is a fan in your cars air conditioning system that pushes air through the vents. If your fan isn’t working, your system can’t blow cool air. It can be as simple as a bad wire or as serious as a fan in need of replacement, but your A/C fan can require your entire dashboard to be taken apart. This can be difficult replacement for many auto owners and people that attempt to do it themselves can risk damaging their interior or dashboard. We always suggest bringing your car into AAMCO of Keller to ensure that your AC fan’s failure can be properly diagnosed.

Reason #2: Your Car’s AC has a Leak

Cars that have a leak in their AC systems are not an uncommon issue for many owners, but that doesn’t mean you should ignore it. Your Vehicle uses a refrigerant known as Freon in your air conditioning system, but when it leaks out of your cooling system, your car will have nothing to dispel heat with. Freon can leak out slowly over time or may drain more quickly out of a larger opening.

If you notice fluid under your car, it’s time to schedule an appointment with our trustworthy mechanics at AAMCO Of Keller. A fluid leak can indicate that you’re A/C is leaking, but it also can be the sign of a much more serious problem. If you notice a leak and your air conditioning isn’t cold give AAMCO of Keller a call for us to schedule an appointment to perform a diagnostic on you cars AC system to see if it’s need of Freon replacement.

Reason #3: Your Car’s AC Compressor Won’t Engage

A compressor uses refrigerant to dispel heat and cool the airflow into your car. If there is an electrical fault in your A/C system, your Freon is low, or your vehicle is overheating, the computer in your car may automatically shut off the compressor to protect the system from damage. If there’s an issue in your engine, the air conditioning system is one of the first systems to be shut off making a terrible situation even harder for many owners.

If this occurs, it can be a sign of other issues. The mechanics at AAMCO Of Keller can check your car for other problems, including electrical issues and overheating issues, to narrow down what could be causing your compressor to shut off or not properly engage.

Reason #3: The Blend Air Door is Stuck

When you switch your car’s climate control from heat to A/C, there is a small door inside your AC’s ventilation system that moves to allow heated or cooled air into the system. This part of the AC system is known as the blend air door, and it can cause a lot of problems with your heating and cooling when it gets stuck. If this door won’t move, your system may continue to blow hot air from the engine, even when you have it switched to air conditioning. This is something that should be checked by a qualified mechanic like the experts at AAMCO of Keller. Should this be the case we can replace your blend air door easily. So contact us to today to schedule an appointment if you’re experiencing any issues with your car’s Air Conditioning system.

The Texas heat is no joke and you don’t want to be left with a vehicle that isn’t properly cooling this summer. AAMCO of Keller is proud to help our customers save on our full range of trustworthy services for your vehicles. Save now with this special coupon for a full A/C Diagnostic.

Your car’s Engine Coolant Temperature Sensor plays a vital role in keeping your cars engine in optimal heat range and not allowing your car to continue to operate above the cars warning level without notifying the driver on the instrument panel of a potential issue. The heat in Texas is no joke in the summer and the team of locally trusted experts at Aamco of Keller are here to keep you and your vehicle on the road safely this summer. Maintaining a level of car tune-ups and preventive maintenance can help catch these potential issues ahead of major repairs.

You may not know when your car could be getting ready to overheat but hopefully your vehicle coolant temperature sensor does. The sensor keeps tabs on the operating temperature and alerts the on-car computer when there’s a potential problem.

How the does the Engine Coolant Temperature Sensor Work?

The coolant temperature sensor (CTS) can be found somewhere near the engine thermostat, which allows it to function optimally. The tip of the CTS is probably located right next to the engine coolant.

The sensor works by measuring the temperature that’s being given off by the thermostat and/or the coolant itself. The temperature is then sent to the on-board control system. From there, your vehicle’s computer will use this temperature information to either continue operating or adjust certain engine functions, always working to keep the engine temperature at an ideal level.

As the control system receives the temperature from the CTS, it may trigger the cooling fan to either shut off or turn on. Additionally, it may signal the need for a richer fuel mixture or open the exhaust gas recirculation.

What happens when a Car’s Engine Coolant Temperature System begins to fail?

As with any other component in your car, the sensor can go bad over time and fall into disrepair. This can cause a range of problems, including overheating the engine.

car radiator overheating

If you know where the engine sensor is and what it looks like, you can conduct a visual inspection to see if it has developed any cracks or fissures. While this visual check can be helpful, it won’t help you diagnose every possible problem as some sensor malfunctions can present without visual evidence.

If your sensor is not working, it will send a signal to the computer and your Check Engine light will be illuminated. If you see the Check Engine sign light up, take your car in for professional servicing right away.

Replacing the Car Engine Coolant Temperature Sensor

The sensor will eventually need to be replaced altogether after time. If the engine sustains any kind of trauma or damage, sensor replacement is always recommended because you don’t want to risk running the vehicle with a faulty one. Even general wear and tear can cause the sensor to erode over time.

You can always have your Car Temperature Sensor replaced by the trusted auto care professionals at Aamco of Keller. Preventative maintenance can certainly save you some headaches and hassle in the long run.

Things such as trouble going into gear, hard shifts or thumps between gears, slipping or jumping gears, delay in acceleration, and strange noises such as whining or grinding are all signs it’s time to change the transmission fluid.

In most cases, getting a transmission flush at AAMCO Of Keller every 30,000 miles, or every two years or so is sufficient. However, there may be times when you need to get a transmission flush sooner, in order to help protect your car’s transmission. There are some common signs that you need to perform a transmission flush on your car or truck.

The transmission consists of about 800 parts, including gears, bell housing, and filters.

Transmission fluid is used in automatic transmission cars as a lubricant that keeps the transmission from overheating and helps power the transmission by creating pressure and torque. Transmission fluid can become dirty, contaminated and worn out. The transmission will not work correctly and ultimately overheat and break down if the fluid is not maintained properly. This is why it’s important to have our team of experts at AAMCO Of Keller do a proper Transmission Fluid Flush.

Problems Shifting Gears

Regardless if you drive an automatic or manual, your car requires clean transmission fluid that flows easily throughout your car’s transmission. A transmission that contains too much dirt or sludge will cause sluggish response in the transmission which will result in your vehicle changing gears too quickly or too late while driving. In manual transmission vehicles, you may find it very hard to change gears at all.

Transmission Grinding or Strange Noises

A vehicle transmission that is contaminated with dirt, grease and sludge can display symptoms very similar to inadequate levels of transmission fluid. When driving your vehicle, if you notice your transmission grinding or making strange sounds, you should stop the vehicle and check the transmission fluid level while the engine is still running. Insure that the transmission fluid color is bright red and not brown or black because of grime or sludge. If the fluid level of the transmission is acceptable, your vehicle probably needs a transmission flush.

Slipping Gears

A dirty transmission may cause a lack of hydraulic power, much the same as not having enough transmission fluid will cause. In order to stay in the appropriate gear, the transmission must develop enough pressure. When a transmission is too dirty, contaminants may interfere with the flow of transmission fluid that helps with this. If you’re transmission has no other problems, and the fluid level of the transmission is full (or close to it), the problem is probably restricted fluid flow due to a buildup of dirt and contaminants that need to be flushed out.

Surging of the Vehicle

When your vehicle’s transmission is polluted with a lot of dirt and contaminants, and needs a transmission flush, you may notice unexplainable surging of your vehicle. Because your car’s dirty transmission does not allow for adequate transmission fluid flow, your vehicle may tend to jump or surge forward and fall backwards for no good reason. This is caused by inconsistent flow of clean transmission fluid that is needed to ensure smooth operation of the gears and other moving parts inside the transmission bell housing.

Delay in Vehicle Movement

Another sign that your vehicle may have contaminated transmission fluid is when the vehicle stalls for one or two seconds before moving after having been put in gear. If there are no other problems with the transmission, a transmission flush may help.

You should be aware that if the vehicle is displaying these symptoms, your dirty transmission may have already caused bigger problems.

Transmission fluid color is a good indicator of wear and tear.

Though color is a good visual way to estimate the age and condition of the transmission fluid, it is not necessarily an indicator of a terrible problem. The color of your transmission fluid is a good place to start when it comes to diagnosing issues, but it does not always give you an accurate measure of its condition. image of transmission fluid color chart If in doubt, the best thing to do is have a professional transmission technician check the transmission, run a diagnosis, and go from there. You might discover there is nothing major wrong, and all you need is a fluid change, or a transmission flush

What’s a transmission fluid flush?

A transmission flush uses pressurized force to send fresh oil and cleaning solvents through the system and remove all of the old fluid and contaminants. New oil is then pumped into the transmission.

A transmission flush acts as a complete cleansing of all the old fluid, but if your transmission fluid has already been contaminated for some time, or the transmission has been running hot and experiencing problems, this procedure might not do much good.

The dreaded Check Engine Light just appeared on your dashboard out of nowhere.
Or you’ve seen it flashing on and off a few times before and maybe you just hoped it would go away by itself.

Your Check Engine Light functions to help ensure your safety on the road.
The light coming on is really just an early warning signal from one of your car’s computers that it notices something is not right that could potentially cause damage to your vehicle, pollute the air, etc. if not taken care of quickly.  It’s important to find out exactly what the light is trying to tell you.

When your car’s Check Engine Light comes on, it could mean a lot of different things are happening within your vehicle.
Issues can range from a weak oxygen sensor, to anti-lock braking system trouble or a more costly problem, like an engine or transmission issue. It could also simply be something very minor, like a loose or missing gas cap.

This system will also produce codes that can be retrieved by AAMCO Keller’s technicians that will tell them just what system or circuit is seeing the problem. Oftentimes, it may take more in-depth testing to pinpoint exactly what in that identified circuit or system is at fault. Without professional testing of the components in the circuit, you could be throwing costly parts at the problem without actually repairing the real problem.

When you see your Check Engine Light come on, the most important thing you can do is to get a correct diagnosis at our AAMCO Of Keller auto repair shop to see what is triggering the light on or flashing as soon as possible.

AAMCO Keller can help you whenever your Check Engine Light comes on.
Our team of expert mechanics at AAMCO Keller will retrieve the codes and tell you what system has caused the light to come on and what will be required to turn the light off.

Your safety on the road is important to us at AAMCO Keller.  If your Check Engine Light is on near Keller and the Fort Worth Area, let one of our expert AAMCO Keller technicians correctly diagnose your vehicle.

For those who do have kiddos heading out on the highways—or for anyone traveling during the spring break season—here are five simple tips for staying safe.cars

  1. Avoid Night Driving

Many road-trippers set off in the evening so they can arrive at their destination in the morning and enjoy a full first day of fun; however, 50 percent of fatal crashes happen at night. Night driving has its own set of risks, two of the most obvious being darkness and fatigue.

Ninety percent of a driver’s reaction depends on vision, and vision is severely limited at night. Depth perception, color recognition and peripheral vision are also worse at night. Fatigue and drowsiness pose substantial risks as concentration and reaction time are impaired. In a worse-case scenario, drivers may even fall asleep and lose control of their vehicle.

Avoid driving at night if possible. If you must drive at night:

  • Drive with a group of friends. Take frequent turns driving and talk with each other to reduce fatigue and drowsiness.
  • Slow down and keep a larger following distance. Reaction time slows at night and it is more difficult to judge speed and distance after dark.
  • Make frequent stops. Get out of your vehicle to increase blood flow and circulation and reduce drowsiness.
  • If you are sleepy or drowsy, quit driving and rest.
  1. Wear Your Seat Belt

Seat belts only save lives when they fit and are worn properly. Though rare, some vehicles on the road still use two-point “lap-belt only” seat belts in the rear center position. If your vehicle has a lap-belt only restraint, avoid sitting in that position unless absolutely necessary. Three-point “lap-shoulder belt” restraints are far more effective at preventing injury than lap-belts alone.  Two friends driving in car

When driving long distances, it is tempting to adjust your seat belt for comfort by incorporating some slack in the belt or even positioning the shoulder belt behind your back. However, these adjustments can make your seat belt completely ineffective and cause severe injury in a collision.

The lap portion of your three-point belt should fit snugly across the bony structures of your hips and pelvis. The shoulder portion should be snug and cross your body at your sternum (breast bone) and shoulder. Make sure to adjust your belt so that it fits properly. Never let the seat belt cross over your neck and never tuck the shoulder belt behind you.

  1. Do Not Recline Your Seat

How many of you have reclined your seat during a long road trip? Did you know that if your car seat is reclined, your seat belt essentially becomes useless?  Seat Collapse

Most passengers simply do not understand the dangers of reclined seats because they assume they are safe if buckled. More space between the seat belt and your body increases the risk of death or serious injury during a collision because your body either slams against the seat belt or “submarines” and slides underneath it.

Car makers have have known about the dangers of reclined seats for at least five decades but have done little to warn motorists. Warnings for this danger are difficult to find because they are likely listed in the back of a several hundred-page owner’s manual. Manufacturers could incorporate a simple light or bell reminding passengers to stay upright (much like a seat belt warning light or chime), but no manufacturer has chosen to incorporate this important safety feature.

  1. Check Your Tires

Tires are one of the most important – and most overlooked – safety components on your vehicle. There are many factors that can compromise tire safety, including tire age, poor tread wear and depth, and improper inflation.  Tire

Older or “aged” tires are a hidden danger because they can fail even if the tread depth is proper and even if they have never been used before. Aged tires can look perfectly fine on the outside but fail at any time. Tires have a safe useful life of no more than six years. Tire makers and car companies have known of the “aged” tire danger for decades but have done little to warn motorists. Tires do not contain an expiration date and it is nearly impossible for an ordinary person (and even some tire specialists) to determine the actual age of a tire because of the archaic codes used.

Have your tire pressure checked before starting your trip and make sure your vehicle has had the alignment checked. Over-inflated tires can lose grip or burst. Under-inflated tires create more rolling resistance, leading to lower gas-mileage and creating excess heat that can lead to catastrophic tire failure, including a blow out or tread separation.

  1. Avoid Distracted Driving

Anything that takes your attention away from driving is a distraction—sending a test message, talking on a cell phone, using a navigation system or eating while driving are distractions that can endanger the driver and vehicle occupants.  iStock_000010527699Small (texting)

Every year, almost half a million people in the U.S. are injured or killed in traffic accidents attributed to texting and driving. At least 47 states and Washington, D.C. have made texting while driving illegal, and the use of cell phones while driving is banned in at least 15 states. Find out how the laws are enforced in the states through which you will be driving.

Even if a state has not outlawed cell phone use or texting while driving, avoid this activity. Studies have shown an increase in collisions and accidents while using these devices.

Stay Safe

If you’re loading up your vehicle with friends and family for a spring break road trip, be sure to check critical safety items before hitting the road. A simple safety check could mean the difference between a spring break that is memorable for fun or tragedy. Travel safe.

If the transmission in your vehicle is slipping, it doesn’t necessarily mean that it’s going to fail on you anytime soon. But if you don’t address the transmission slipping, it could very well force you to make major transmission repairs at some point in the future.

Replacing a transmission in a car, truck, or SUV can cost anywhere from $1,000 all the way up to $6,000 in some cases. It can also put your vehicle on the shelf for a few weeks, which is why you should avoid it at all costs.

There are a number of things that can cause a slipping transmission. In some cases, you can stop the slipping by making a minor repair. In others, it’ll take more time and money to fix the problem. Either way, you should stop transmission slipping ASAP.

Keep reading to learn about common causes for a slipping transmission.

First, What Are Signs of a Slipping Transmission?

Before we start talking about what causes transmission slipping, it’s important for you to know some of the signs of it. By educating yourself about the signs of a slipping transmission, you can keep an eye out for them when you’re behind the wheel.

Your transmission might be slipping if you notice any of these things taking place:

  • You experience delays in acceleration when you step on the gas in your vehicle
  • You notice that your car seems to struggle to shift from one gear to the next
  • You see a high RPM on your dashboard when you’re driving
  • You smell something burning while you’re driving
  • Your check engine light comes on and indicates an issue with your transmission

Don’t ignore these signs! They could be letting you know that your transmission is slipping.

Now, let’s check out some things that can cause automatic transmission slippage.

1. Not Enough Transmission Fluid

Is there a chance that your vehicle might not have enough transmission fluid in it? If so, that could be causing you to experience a slipping transmission.

Unfortunately, a lot of today’s cars don’t have dipsticks in them that allow you to check your transmission fluid level. But if you are low on transmission fluid, it’s usually because there is a problem somewhere in your system that’s causing the transmission fluid to leak.

You should, therefore, keep an eye out for signs of a transmission fluid leak. Transmission fluid is typically red in color and slick and will often pool underneath of your car when it’s leaking out. It’ll be important for you to find the source of the leak and have it repaired to stop this problem from reoccurring so that your transmission stops slipping and causing further damage.

If you must drive the vehicle, topping off the fluid to the full mark on the dipstick should get you to the repair facility if the leak is not too severe. If the leak is severe, have the vehicle towed and do not drive it as that will cause severe damage to the internal lubricated parts.

If you don’t fix the leak and keep enough transmission fluid in your vehicle, it will lead to overheating. It could also lead to a lack of hydraulic pressure in your transmission, which will often cause your transmission to slip and struggle when it tries to engage and change from one gear to the next.

Outside of fixing the leaks, you should also find out how often your car’s manufacturer recommends having your transmission fluid replaced. Most modern cars, trucks, and SUVs rely on synthetic fluids that will last for an extended time, but you will likely need to replace your transmission fluid at some point.

You’ll need to be extra mindful about replacing your transmission fluid more often if you tow with your vehicle or live in an area with hills, a lot of stop and go traffic, or severe weather. Most car manufacturers will provide severe service recommendations that is more often and for less mileage for those vehicles that experience any of these categories.

Follow the recommendations given to you by your car’s manufacturer so that you know your vehicle always has the correct, fresh transmission fluid in it. Stay vigilant to leak and you will avoid transmission slipping for an extended period of time.

2. Transmission Bands That Are Worn or Broken

Most automatic transmissions have a devices or devices called bands that are an important friction device used to shift various gears in a transmission. Those bands need to stay strong and connected to help you avoid a slipping or harsh shifting transmission.

But over time, all friction wears and the bands in your transmission can break or wear due to the stresses put on your vehicle.

The only way to repair this particular problem is by bringing your vehicle in for service and having the bands that have broken or worn down replaced during an overhaul. This will stop your transmission from shifting improperly or slipping while you’re driving your car.

3. Worn Out Clutch Plates

Those with manual transmissions in their vehicles are all too familiar with the clutch that they use to disengage the engine from the transmission in order to switch gears without grinding. But it’s important to remember that automatic transmissions also have clutches as well, even though the driver doesn’t have to worry about controlling it themselves.

These clutches are made up of plates that consist of steel plates with friction material attached to them and steel plates with no friction on them, all sandwiched together in a pack. These clutch plates in an automatic operate in that precious transmission fluid and play an integral role in the operation of your clutch as a whole.

But automatic transmission clutch plates are paper thin, and if the transmission is not maintained with fluid changes and leak avoidance, it’s not uncommon at all for the friction material in clutch plates to wear out over time and cause transmission slipping.

The problem is that, once this material has worn away, there is no reversing the damage that has been done. Your transmission is going to continue to slip until the transmission has been overhauled and the worn clutch plates and other parts have been replaced.

4. Worn Out Gears

The gears in your transmission are some the most rugged parts in the transmission but also some of the most important parts in it, too. The gears are called planetary gears and they play an important part in compounding ratios that allow you to go faster and put your car into reverse.

Transmission gears are designed to last for a long time and can put up with almost anything that you throw at them. But like all auto parts, they can break and wear down over the years before finally giving out on you altogether.

When your planetary gears brak down, they won’t be able to mesh properly with the companion gears like they normally do. This can cause your vehicle to make horrible noises and jerk around a lot when you’re driving.

If your transmission has problems because of an issue with your gears, they’ll need to be replaced during an overhaul before you can start driving your car again. The problem is that when you have damage to metal gears, the metal that comes off of those parts travel all through the transmission and into some extremely sensitive solenoids, valves, and passages. A complete overhaul is often necessary to remove the debris.

5. Malfunctioning Solenoid

Unless you’re a gearhead or someone who has experienced transmission problems with your car in the past, you might not know what the solenoid is. But solenoids in today’s modern electronic transmission play a very important role in the overall well-being of your transmission’s operation

The solenoid is an electrohydraulic valve that controls how much transmission fluid is allowed to pass through your transmission at any given time. It’s the gatekeeper for your transmission in a lot of ways and must be working for your transmission to not slip and to shift properly.

If any of the many solenoids in your transmission are ever damaged or if there are ever any electrical issues with them, they might start to allow too much transmission fluid or too little transmission fluid to pass through your transmission’s shifting passages and pressure controls. This can, as you might expect, lead to lots of problems, including transmission overheating and slipping.

A damaged solenoid will need to be replaced to stop the slipping from taking place. It’s a pretty inexpensive part in the grand scheme of things, but it can make a world of a difference for your transmission.

6. Failing Torque Converter

Torque converters are another aspect of your transmission that not everyone knows about. But much like solenoids, the torque converters in transmissions play an important part in their operation.

A torque converter is a fluid coupler that also contains a friction clutch in it that locks up solid when you go into overdrive in order to provide you with better gas mileage. Until it goes into lock-up, it actually slips by design since it uses fluid to drive the transmission.

But problems can arise when a torque converter fails to do its job properly. When a torque converter malfunctions, it can cause an excessive amount of heat to build up inside of a transmission, and that heat can do damage to the rest of the transmission.

AAMCO Of Keller Supports Gold Star Family Monument

AAMCO Of Keller is proud to be a supporter of the Keller Gold Star Family Monument through not only donations but AAMCO of Keller Owner David Gerda is also a supporting committee member. Fox 4 News released the following story on the Gold Star Family Monument.

Gold Star Monument

KELLER, Texas – The city of Keller is honoring the families of fallen American service members.

An eighth grader came up with the idea of a fundraiser to build a monument in the city.

“These families have gone through so much. They’ve made a huge sacrifice as well as their fallen service member and it’s just good to give them support, their whole family, not just one person in the family. Family, friends… it’s just important to share the love,” said Erin Stillinger, who attends Indian Springs Middle School.

The last remaining Medal of Honor recipient from the Battle of Iwo Jima in World War II was at the groundbreaking ceremony Sunday to help encourage donations. Retired Marine Corps Chief Warrant Officer “Woody” Williams travels the country at age 95 to push for this kind of memorial.

“This thing isn’t about me at all. It’s about them. And as I say in my motto, the cause is greater than I,” he said.

The goal is to raise $65,000 to build the monument. The foundation has raised $26,000 so far.

Donations for the Keller Gold Star Family Monument can be made at http://www.hwwmohf.org/keller-tx.html
