Most of the time, you dont hear about transmission repairs because more often than not, most automotive shops do not know how to open up a transmission. However, Weber Automotive can, and we can usually repair your transmission at a fraction of the cost of replacing it with the other guys. What is a Transmission? The transmission is the part of your car which converts power from the engine, allowing gears to change, moving the wheels, making the car drive forward. Below you can see an image of an animated dissected transmission. Transmission Fluid Each manufacturer has their own recommendation for how often to change your transmission fluid. However, most manufacturers are now claiming that transmission fluid will be good for the life of the transmission. This is true, but pieces of clutch plates accumulate in the fluid, which causes it to wear seals, gaskets, and hoses over time.
