What Is the Automobile Transaxle?
Definition The word “transaxle” is a portmanteau of the words “transmission” and “axle.” A transaxle combines the function of a transmission with that of an axle. Transmission vs. Transaxle A transaxle incorporates all of the components of any other transmission but also includes a differential and final drive gear set. Applications Transaxles are used in front-wheel-drive cars, mid-engine sports cars, most all-wheel-drive (AWD) cars and some rear-wheel-drive cars, such as the Chevrolet Corvette and Mazda Miata. Rear-Drive Applications Transaxles used in rear-wheel-drive cars are located in the back and connected to the engine with a driveshaft. Rear transaxles are used in these applications to shift the car’s weight balance toward the back. AWD Transaxles AWD transaxles incorporate a separate differential that is connected to the rear axle with a shaft. This differential controls front-to-rear power distribution.
