Why are transmission repairs so expensive?

Quite simply, transmission repairs are expensive because your car's transmission is a very complex system of gears that transmit power to your engine. Repairing a transmission is a difficult and time-consuming process that requires skilled professionals.


Your vehicle's transmission transmits power to your engine, and that determines the rate of speed at which you travel. The transmission converts engine power so it supplies high torque at low speeds, and it selects the proper gears for the current driving conditions.


Automatic transmissions - by far the most common kind in cars in the United States - are even more complicated. An automatic transmission uses a torque converter to control the number of gears in use. Supplying the power that regulates the gear action is very demanding, and it requires a lot of parts to operate smoothly and correctly. Even the smallest problem can quickly turn into a major catastrophe.
