If your Mercedes-Benz is equipped with an automatic transmission, you already know how convenient they are. Rather than constantly focusing on your speed, engine RPMs, and timing your gear shifts, you let the vehicle do all the work. When you're stuck in stop-and-go traffic, that's quite a blessing.

An automatic transmission keeps all the gears in one place, in a circular structure similar to that of a solar system. There's an outer ring gear, a central gear, and two or more smaller gears that all connect together. An input shaft connects to the outer ring gear, delivering the engine's power. The smaller gears sit inside a casing that connects to an output shaft, which delivers that power to the drivetrain and wheels.

Of course, no transmission can change gears while it's engaged with the engine. Rather than the clutch that manual transmissions use to temporarily disengage the two, automatic transmissions feature a torque converter. The oil pump delivers the transmission fluid that covers all of the parts in your automatic transmission's hydraulic system.

A brake band is used to temporarily hold the smaller gears while the engine RPMs get to the proper gear ratio. The transmission also features an oil pan that holds any excess transmission fluid. Finally, a valve body manages the entire process to ensure that transmission fluid goes where it needs to, when it needs to, and in the desired levels.
