Transmission Failure: 7 Signs That your Transmission may be Failing

Your car’s automatic transmission is the behind-the-scenes workhorse of your engine, constantly shifting up and down through your gears to smoothly and silently transfer power to your wheels. When it works correctly, you don’t notice it—and that’s the whole point. However, the longer your transmission is in service, the more susceptible it could be to problems.

Sometimes, the issue is inexpensively fixed, but if left unchecked, you could find yourself in need of a full transmission overhaul, which can be an expensive and technical repair job. It’s worth knowing some early signs of a potential transmission failure, so you can catch developing problems before it’s too late.

7 Early Signs of Potential Transmission Failure

Transmission Warning Light

While the transmission warning light turning on may sound obvious, a surprising number of drivers will ignore their dashboard indicator lights. Some models have a specific transmission warning light, while others will have a general “check engine” light that can signal early transmission failure. In either case, you should take your car to a repair shop to check up on those warning lights as soon as they pop up.

Bumping Noises While in Neutral

You’d think that there wouldn’t be anything to look out for while your transmission is in neutral since your vehicle is not in motion. If you are hearing bumping noises in neutral, this might indicate that the transmission fluid is low or in need of replacement. Follow the instructions in your owner’s manual to test the dipstick under the hood to make sure the level is right and the fluid is still bright red and sweet-smelling (and not dark brown and burnt-smelling).

Noises in neutral could also indicate a mechanical problem, like a worn idler gear or work bearings. If a top off of your transmission fluid–follow the instructions in your owner’s manual–doesn’t resolve the problem, you should visit your mechanic to have them take a look.

Leaking Transmission Fluid

Automatic transmissions are closed systems. Unlike your engine’s motor oil, there is no reason why a transmission should leak or burn up its fluid. If you notice a puddle of bright red or dark brown fluid under the center of the car, that could be a sign of impending transmission failure. You should have a mechanic track down the source of the leak.

Whining Noises

You need to keep your ears open to notice this warning sign. When a transmission is starting to experience distress, it will sometimes start to emit a whining, whirring, humming or even a slight buzzing sound when in use. Often these noises are intermittent at first, but, if you don’t get them checked, they will happen more often over time and increase the risk of serious damage.

Uneven Gear Shifting

This is another warning sign that occurs when you’re out on the road. A properly functioning automatic transmission will shift almost imperceptibly between gears. The sensors are designed to transfer power as smoothly and efficiently as possible. However, if your transmission is having problems, you may start to feel a kind of shimmy or shudder when it attempts to shift from one gear to the next. That sensation can be one of the early signs of transmission failure.

Transmission Hesitation

This warning sign feels less like a stumble or a stutter during shifting, and more like an annoying pause before the next gear engages. If your automatic transmission starts hesitating between gears, it’s going to feel like something is off. You’ll want to have a mechanic examine the system. Not being able to rely on your transmission to give you more power when you need it can be a real safety hazard, especially in highway driving conditions.

Slipping Gears

If a car starts to slip gears, this is a clear and present danger that needs to be examined by a mechanic as soon as possible. When a car spontaneously slips out of one gear while driving, popping down to a lower gear, it’s time to get the car examined pronto.

 

Here are a few signs of transmission problems to consider:

• If you notice that your car is dripping a red fluid, that is most likely transmission fluid. Check on the ground where your car is normally parked. If you find that you have more than a few small drops, you may need transmission repair in a hurry. If your fluid is low, you can add transmission fluid to your car in order to protect it from damage while you drive it to the auto mechanic.
• When you are driving, the shifting between gears in an automatic transmission car should operate almost silently and imperceptibly. If you are having problems with your transmission, you may notice that there are vibrations or hesitancy when shifting through different gears as you drive. An auto mechanic with complete car care service expertise will be able to advise you about the problem and determine what type of transmission repair can get you back on the road.
• When your transmission doesn’t have enough fluid, you may experience it stalling at red lights or stop signs. Though it should start right back up, taking your car to an auto shop for repair is key as your transmission lines may be leaking and may need to be replaced. Though still not a small repair, getting new transmission lines can make sure that your transmission is getting the fluid it needs to operate and can be less costly than an entirely new transmission or rebuild.
• Fluid color.

Transmission fluid that has come from an overheated transmission isn’t generally red; it will appear dark brown or black as a result of being exposed to high temperatures. If you find that your transmission fluid isn’t maintaining its red color, then it is time to get your car in for repair.

 

Understanding Automatic Transmissions

The transmission transfers torque from the engine to the wheels to provide optimum power to negotiate various driving conditions. In a manual transmission, this is achieved when the driver selects the right gear depending on driving conditions.

Automatic transmissions select the right gear ratio without any driver intervention. Both manual and automatic transmissions give a fixed number of gear ratios. A CVT, on the other hand, gives a theoretically infinite number of gear ratios within a fixed range.

A manual transmission needs maintenance and it is checked during periodic service. It can also be easily repaired. But, automatics and CVTs are relatively maintenance free, at least according to most manufacturers.

 

Symptoms Of Transmission Problems

You know you have a transmission problem when your car starts behaving strangely. The gear shift becomes less smooth. Sometimes, the engine revs, but the car does not move forward. These symptoms may not be a problem initially, but they tend to get worse and after some time, become serious causes of concern.

When the symptoms become very acute, it pretty much spells the end of the transmission. Fixing the transmission in time can help prevent such problems and save you the huge cost of a new transmission. The trick is to prevent the transmission from getting to the point of no return.

Servicing An Automatic Transmission

Although saving the transmission is easier in the early stages, there is no harm in attempting a transmission fluid flush even at a later stage. In many cases, changing the transmission fluid can restore the performance of the transmission to a great extent even if the symptoms are acute. There is no guarantee, but it often works and is a good and inexpensive way to fix the issue.

A new transmission costs almost ten times the cost of flushing the transmission fluid. So, it makes sense to attempt the repair. It may not restore the transmission to its full performance, but some symptoms disappear and others become less dramatic. Maintaining the transmission in the early stages is much better than taking this gamble.

 

Servicing a CVT

Unlike a manual or an automatic gearbox, a CVT can theoretically offer infinite gear ratios within a range. This offers the right power for all types of driving conditions and great fuel economy.

Most manufacturers do not expect any maintenance on a CVT. That’s why, transmission fluid changes are usually absent from manufacturer-specified vehicle service schedules. A fluid change is not recommended as it is a “lifetime” fluid. What they don’t mention is that the life of the transmission is only about 120,000 km without maintenance and replacement is expensive.

Replacement costs are high due to the complex nature of the transmission. A new transmission could set you back by £3,000 to £6,000. A fluid change can significantly extend transmission life. CVT transmission fluid is relatively inexpensive and the entire job should cost only about £200. It is definitely the better option.

Automatic Transmission

Automatic Transmissions shift between gears automatically to optimize driving, and changes gears based on the driver’s throttle pedal, vehicle speed, engine speed, and vehicle load. Typical automatic transmissions have 4-5 forward gear ratios, a Reverse, Park, and Neutral gear. Shifting gears occur automatically once the car is in Drive and there is no need for a clutch pedal or gear shift like there is in a Manual Transmission. Automatic transmission repair is complicated based on all the components that make it up, and you need to have any automatic transmission issues properly assessed by auto mechanics.

Clutches

There are clutches in both automatic and manual transmission cars, and different types of clutches. When shifting gears, the clutch engages and disengages from the flywheel and transfers the torque through the transmission. Clutches should help your vehicle start and shift gears smoothly. The clutch in your car receives a lot of wear and can eventually wear out

Four-Wheel Drive Transmission

A four-wheel (4×4) drive vehicle has differential gears, both front and rear axles, and a transfer case attached to the transmission. Four-wheel drive vehicles demand maintenance on the transfer case, front differentials, rear differentials, and transmission fluids

Front-Wheel Drive Transmission

If your vehicle has Front-wheel drive, the engine drives the front wheels only. The power is routed through the transmission to the final drive where it is split and sent to the two front wheels through the drive axles. The engine, transmission, and additional hardware is all located in the front of the car

Manual Transmission

Driving a vehicle with a Manual Transmission requires using the clutch pedal and gear shift to manually shift gears based on the speed of the vehicle. Manual transmissions have been built with anywhere from two to eight gears. Front-wheel drive and rear-wheel drive are the two main configurations for manual transmissions. Typically, manual transmissions require less maintenance then automatic transmissions.

 

Best Transmission Additives: Restore Your Transmission’s Health for Smoother Performance

If your vehicle’s transmission suddenly starts shuddering, or the changes feel harsh and uncomfortable, it could be an indication that your transmission is faulty and needs your attention. More often than not, these issues can be due to the lack of proper transmission fluid.

Fortunately, you don’t have to spend a lot of your hard earned cash replacing your vehicle’s transmission. Instead, you can go for a much simpler and affordable option and shop for the best transmission additive. To make your search easier, here’s our list of the best transmission additives on the market right now.

Stop transmission leaks. Having a transmission leak might seem like a minor issue, but its aftermath could be profound. A small transmission leak could cause your transmission system to operate poorly. Transmission fluid is corrosive, so having small leaks could damage parts close by. Therefore, investing in a good transmission additive will help minimize leaks.

Minimize varnish and sludge formation. After extensive use, even high-quality transmission fluids begin to wear out and thicken. This happens when dirt and other contaminants mix with the fluid forming sludge. Thick fluid moves slowly, preventing the transmission parts from moving easily and efficiently. Getting proper treatment keeps your automatic transmission fluid (ATF) viscous, helping your transmission work as it should.

Reduce gearbox wear and tear. When gear oil moves throughout your vehicle’s transmission, it keeps your entire system working properly. However, when transmission fluid starts getting old, thickens, or forms impurities, your transmission will be forced to work harder and won’t be as effective. The harder your transmission system works, the more wear will be put on your auto parts.

 

TRANSMISSION REPAIR SERVICES

understand the terror that comes with the words “transmission repair” and we want you to know that there is hope after all. Whether manual or automatic, heavy duty or low range, the transmission is a vital part at the center of your vehicle’s drivetrain. Your transmission is instrumental in turning the engine’s power into forward movement, so it’s not surprising that problems with this important component can cripple your car

One of the easiest ways to avoid a large transmission repair bill is to flush the fluid according to the vehicle manufacturer’s guidelines. Your transmission contains a lot of intricate moving parts which can deteriorate quickly if not properly lubricated

Sometimes our technicians don’t get to look at the problem until after something has gone wrong. While this is certainly more serious than a simple transmission fluid change, it doesn’t have to spell disaster

At its most basic, your car’s clutch allows the engine and gearbox to engage and disengage from each other between gear changes. This means that although the engine’s output shaft is still spinning, there is no load on the gears which may cause them to shift improperly. Once the next gear is smoothly selected your clutch will re-engage the engine and gearbox, resuming forward momentum. Over time, and especially in improperly operated manual transmission vehicles, the clutch can become worn and less effective at its job. A damaged clutch can allow the engine and gearbox to re-engage mid-gear change, and this can have serious effects on the health of your transmission.

Another area of our gear-based expertise is your car’s differentials. These sit in the middle of your car’s axles between the wheels and are vital for a smooth ride. As you turn a corner, the outside wheel has to travel a greater distance than the inside wheel. Without properly functioning differentials, the wheels would turn at the same rate causing your car to vibrate horribly, and struggle to turn whenever you tried to go around a corner.

 

Trust Your Transmission Repair

Do you hear noises or notice erratic shifting from the transmission? These are some common signs there may be a problem with your vehicle’s transmission. If you’re like most people, the thought of having transmission repair problems causes great concern.  It’s an understandable reaction.

An automatic transmission is a sophisticated engine component, and its performance can be affected by any number of things – some minor and some major.  That’s why it’s important to trust any maintenance and repairs to an auto repair shop with an excellent reputation

Maintaining an Automatic Transmission is Important for Performance

As with any system in your vehicle, proper maintenance is integral in making sure it doesn’t break down. This is especially important when it comes to the transmission. A good number of car owners never have the transmission fluid and filter replaced and then wonder why the transmission begins to shift poorly or make clunking sounds. When one evaluates the cost of replacing a transmission versus the cost of regular maintenance, the expense of routine fluid and filter changes is much more desirable. In fact, it ends up being money well spent.

An automatic transmission should be service every 25,000 to 30,000 miles. Doing so will significantly prolong the life of the transmission in your car, truck or van. A word of caution, however… If you have never changed the transmission fluid or filter and your vehicle’s mileage is nearing 80,000 to 100,000 miles, be very cautious about having a transmission service done. In fact, we recommend you check with us before doing so as it could cause unexpected problems with the transmission

if you notice any of the following:

Low Transmission Fluid – If you check the transmission fluid level and find you need to add more, there’s most likely a leak in the system that needs to be repaired.

Red Fluid Under Your Vehicle  – There are two types of fluid that are red in color – power steering and transmission fluid. If it’s under your vehicle, it means there’s a leak in one of these systems.

The Transmission Fluid is Black or Smells Like It’s Burnt  – Your transmission fluid should be a clear red and should not look cloudy, have a burnt smell or be dark brown or black in color. If you do notice any of these signs, it is because something is causing your transmission to run too hot. Schedule an appointment to have us check out your car’s transmission.

Any Noises or Erratic Shifting – Don’t ignore even the slightest of symptoms. Sometimes it could be a simple adjustment that needs to be made. If this type of shifting behavior is allowed to continue, it may turn into a major transmission repair.
