Operation
The term power transmission refers to the transmission of propulsion power and engine torques. Via the mechanical/hydraulic connection between the engine, torque converter and the downstream automatic transmission the engine torques are transmitted to the driving wheels and are converted in the transmission via several planetary gear sets. Power is transferred in the torque converter via the driven impeller by diverting hydraulic fluid to the turbine wheel, which is connected to the input shaft.

When the torque converter lockup clutch is engaged, power is transmitted via this mechanical connection. Via the gearwheels of the individual planetary gear sets the torques coming from the converter are passed on to the output shaft with the aid of freewheels, multi-disk clutches and brakes, depending on the ratio and shift element operated

A reduction of the output speed in the low gears provides lower vehicle speeds with high tractive forces and drive torques at the drive wheels.
