Transaxle refers to a mechanical device that merges the functions of an automobile's transmission, axle, and differential into one integrated assembly. Both manual and automatic versions are available.

  • There are three reasons for having a transmission or transaxle in the automotive power train or drive train. 
  • It can provide the torque needed to move the vehicle under a variety of road and load conditions
  • It can change the gear ratio between the engine crankshaft and vehicle drive wheels
  • The transaxle can be shifted into reverse so the vehicle can move backward.
  • It can be shifted into neutral for starting the engine and running it without turning the drive wheels
