  • Changes the direction of the driving power.
  • Final gear reduction.
  • Allows drive wheels to rotate at different speeds when cornering.


Transmits power from the differential to the wheel.



A transaxle is a transmission and differential combined into one unit, used in front-wheel drive vehicles.


Uses gears to transmit power from the engine to the drive wheels. Selecting different gears changes the amount of power and torque transmitted.



The clutch either transmits or isolates the power from the engine to the transmission.

Propeller shaft

On front engine rear-wheel drive vehicles, the propeller shaft transmits power from the transmission to the differential.
