A transmission and differential combined in one integrated assembly. The transmission is a gearbox with a number of selectable ratios, used to match the engineâ€(tm)s RPM and torque to differing vehicle requirements.
This mechanism combines the duties of a differential and a transmission, and is commonly used in front wheel drive (FWD) automobiles. Having a transaxle means that there is no need for the drive shafts which are used to connect the differential to the transmission in rear wheel drive (RWD) cars.
A transaxle, in the automotive field, is a component that combines the functionality of the transmission, the differential and the drive axle into one integrated assembly. Transaxles are near universal in all automobile configurations that have the engine placed at the same end of the car as the driven wheels: the front wheel drive, rear-engined and mid-engined arrangements.
