A slipping transmission is a common problem with many automatic cars. Knowing what usually causes the problem is critical to ensuring that you take proper care of your auto transmission and also seek repair service when the need arises.
Here is a look at some of the most common causes of a slipping auto transmission and how to deal with each:
Burnt or ineffective transmission fluid.
If you can smell your transmission fluid burning, you should know that all is not well with your transmission. In most instances, burning transmission fluid is as a result of overheating of the transmission. Ineffective transmission fluid, on the other hand, is usually caused by contamination that occurs due to normal wear and tear of transmission components, especially during metal-to-metal grinding.
You can tell if your transmission fluid is ineffective by checking its colour. If the fluid has lost its bright red colour and tart (sweet) smell, those are tell-tale signs that it is time for transmission fluid change.
Problems with the transmission bands.
Your transmission bands link your car gears so you can shift gears smoothly. Loose or broken transmission bands could lead to a slipping transmission. In addition, they can affect the overall performance of your car engine. To remedy problems with your transmission bands, you should make sure any loose bands are adjusted. Damaged bands should be repaired or replaced, depending on the extent of the damage.
Transmission fluid leaks.
Low transmission fluid levels are another probable cause of a slipping transmission. Low fluid levels are usually a sign of an underlying problem — transmission fluid leaks. The sooner you detect leak spots in your transmission and initiate repairs, the better. Otherwise, you will be exposing your auto transmission to extensive damage. If you find any transmission fluid leaks, you should have them properly sealed as soon as possible.
Problems with the torque converter.
The torque converter is the all-important system of parts including a stator, an impeller, a turbine, and a lock-up clutch, connecting the engine to the transmission in order to make the wheels turn. If any of the torque converter components cannot lock into the chosen gear, the transmission may slip. If your torque converter system is faulty, you can rely on a qualified mechanic to find the exact cause of the problem.
Periodic servicing of your transmission would help you prevent transmission slipping. A qualified mechanic can provide the car repairs your transmission needs to keep running smoothly and efficiently.
