What would cause the transmission not to engage?

Low fluid level. The most common cause of slipping is low fluid levels. Low fluid levels can cause a number of problems, for example B. Overheating and insufficient hydraulic pressure to start the gears. The bands connect the gears of an automatic transmission.


August 2020 Update:





Your vehicle’s transmission is a complex mechanical system that controls the transmission of power from the engine to the drive shaft. Due to the heat and friction generated by many moving and interacting components, more wear occurs over time than in most other parts of your car. At the end of this page you will find guidance on the fair value of replacing popular gear models.

Repairing or replacing gears is uncomfortable, tense, and usually quite expensive. Therefore, it is advisable to follow unusual actions. Following recommended maintenance procedures and a schedule to avoid problems will help your drivetrain run longer, perform better and require fewer repairs over its lifetime

Serious problems can occur if your transmission is not in good condition and / or if the symptoms of the problem were not checked by a professional soon after they developed.

How To Diagnose A Problem

Identifying problems with your car seems unfulfilledyour task, especially for the inexperienced eyes and ears of the average driver. It may be helpful to think that the interior of your car is similar to the interior of a human body.

To diagnose problems with the car yourself, try looking at them from your body. For example, if your stomach begins to hurt without warning, you will probably think about the last thing you ate to find out why you are hurting.

A similar way of thinking is associated with the diagnosis of problems with the car. Problems with mechanical systems usually have different feelings and noises, which serve as indicators that a particular process is not working as expected.

Once you find that something is wrong with the functionality of your car, it's time to research the problem and find a way to solve it.

However, if you have problems with the car, it is important to know what are the most common transmission problems so that you can easily diagnose and solve them. Here is a list of 10 symptoms of transmission disorders and signs to look for.

Missing Answeror Switch Delay

Have you ever noticed that a car is hesitating or refuses to shift gears while driving? If so, then something is definitely wrong. As soon as the driver switches from parking to driving, the correct gear should be selected immediately. In the case of automatic transmissions, you may notice that when switching to driving or parking mode, there is a delay before switching to gear. This is usually a transmission problem.

Manual gearboxes may have the same problem, but after switching the engine speeds increase, but the car does not move as fast as it seems. Usually this is due to the clutch, which must be replaced, but sometimes it can indicate a more serious problem.

Whine, Clink Glasses And Buzz

It is impossible to say exactly what your car will look like if there are problems with the transmission, but one thing is certain: if you notice this, you will have the impression: “I never heard this sound before.” The generated sounds vary significantly in forDepending on the make and model. However, the best way to describe this is that you are most likely to hear a buzzing, buzzing or moaning sound.

A manual transmission makes sounds that can be described as somewhat mechanical, louder and sharper. A rattle sounds when you almost always shift gears when a constant speed follows, or the differential may be the reason the rattle comes out from under your car.

As mentioned earlier, it’s always better to diagnose and fix the problem as soon as possible, rather than wait until you “find the time” or “get the money”. If you wait later, relatively inexpensive repairs can easily become much more expensive.

Leakage / Low Fluid

The leak is probably the most recognizable symptom and should be fixed as soon as possible. One of the most common causes of transmission failure is fluid leakage. Automatic Transmission Fluid (ATF) is the transmission's lifeblood because it lubricates, cleans and condition seals and acts as a hydrauliceskaya liquid. Otherwise (or even if it becomes too low), the engine will lock up and stop working completely.

ATF is bright red, transparent and smells a little sweet if everything works correctly. If this is what you find on your way, then all you need to fix is ​​a hole. If the liquid is dark and / or has a burning smell, it is time to change or rinse, and repairs may be required.

To check if you are short of fluid, drive the car briefly to warm it. Then raise the hood and read the pointer (make sure the car is on a flat surface). Unlike engine oil, transmission oil is not burned or consumed by the car. If the level is low, then somewhere there is a leak that needs to be fixed. In any case, it is recommended to top up, even if the leak is still present, to ensure that there is enough fluid for the gearbox to work properly until you repair it.

To check the fluid level in a manual gearbox, check the card the gearbox (usually through the filler cap), not the dipstick under the hood.

Chop Or Shake

The car should move silently, not tremble and not twitch, and there should be no cracks. All this indicates that there is a problem with the gears. Manual transmissions often indicate problems, causing creaking or noise when shifting gears. If grinding occurs after engaging and replacing the clutch, this may indicate the need to replace or adjust the clutch. However, this can also indicate many other problems, including damaged or worn speed synchronizers.

Automatic transmissions behave somewhat differently. Instead of crackling, it will probably take some time for the equipment to turn on, rather than typical fluid transitions. If the problem worsens, transitions to the next speed will become sharper and require more shaking. There are many other reasons to grind or shake, but the best solution is to check and repair.

Burning Appah

Any burning smell from your car is a concern. One of the causes of a burning smell is overheating of the transmission fluid. Gear oil lubricates and cools parts so that they are not worn or damaged.

If the fluid decomposes, the system is too hot, which increases friction and corrosion, as well as the formation of additional sediment and dirt. If this is not done, the transmission will be so badly damaged that it will completely stop. The end result is an expensive replacement. Common causes are low fluid levels or the use of the wrong brand / type of fluid. See Instructions in the Weak / Leaking Fluid section above.

Refuses To Choose Speed

If the car does not move after engaging the clutch and trying to move the control lever, check the fluid to make sure it is in the correct position. Other reasons are the use of a fluid of the wrong thickness (type) and a clutch or shift cable that needs to be removedto walk. The cause of the problem could also be the computer system of the car.

If you have already tested the fluid, try dumping it. To do this, remove the battery and leave it on for 30 minutes. Reconnect the system and perform a reset. It usually takes about 30 minutes. If that doesn't work either, it's time to take it to the mechanic.

Check The Engine Bulb

The warning light on the dashboard of your car is a good indicator that something is wrong (or has already happened) in your car and especially in your gearbox. Although the light comes on for a number of reasons, in addition to transmission problems, it is very important not to ignore this useful warning sign.

In many areas of a car’s engine, sensors alert the computer when unusual activity is detected as a result of a specific process. Transmission sensors can detect the slightest jolts and vibrations that you cannot see or feel.

Pick up the car and inspect it. Using similar diagnostic tools and a car computer, they immediately see thatIt is happening. You can also view a list of the most common transmission diagnostic codes.
