Transmission Service

Our professionals here at Stephens Automotive will fix or replace your transmission as needed in Des Moines, IA.

The transmission is necessary for your vehicle to run correctly. It converts the engine’s force into a controlled source of power. The transmission converts the engine’s power into torque that turns the axles and then rotates the wheels in an efficient way. Using gear ratios, the transmission keeps the revolutions per minute (RPMs) for the engine and the wheels at optimal rates.

There are two different kinds of transmissions. Automatic and manual transmissions have different benefits and drawbacks, and they work slightly differently. Transmission fluid acts as a cooling agent that protects the transmission, keeps it from overheating, and lubricates the internal gears to prevent rust and corrosion. In an automatic transmission, the fluid also applies pressure and force to help change gears. Manual transmissions use clutches and gear shifts to do this.
