What Causes Transmission Repair

Transmission failure can often be traced back to one of several causes, most of which are easy to diagnose and fix. When your car's transmission is failing, you may experience a number of symptoms, including jerking and popping while driving, poor fuel mileage, and difficulty shifting gears. Here are some of the most common causes of transmission failure:

-Leaking or failed fluid seals:

This is the most common cause of transmissions repair, as seals around the engine and gearbox can dry out over time and fail catastrophically. If you notice your car lagging behind in acceleration or losing power when you take it off the line, there's a good chance your fluid seals are leaking. In many cases, a simple sealant treatment can solve the issue.


Overheating can also lead to transmission failure by damaging components inside the Gearbox. This includes the input shaft, planetary gear set, and other vital parts. If your car starts smoking or making unusual noises after running for a long period of time, there's a good chance it's overheating and needs to be fixed as soon as possible.


Rust is another common cause of transmission problems. Whether it's on the outside or inside, it can be very dangerous to your transmission. Do not ignore any rust spots that appear on your transmission. Getting rid of them is a must.
