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.
