A transaxle is a complex machine that brings together a transmission and final drive components like a differential. In that way, a transaxle is capable of driving the axles without any additional components.
Contemporary front-wheel-drive vehicles often will combine the transmission and the front axle into what is called a transaxle. On vehicles with rear-wheel drive, the engine connects to a drive shaft, and the drive shaft turns the drive axle in the back of the vehicle.
