What are the primary components of a transaxle?

A transaxle is a key component in a vehicle's drivetrain, primarily responsible for integrating the transmission and differential into a single assembly. This design allows for more efficient space usage in front-wheel-drive vehicles. The primary components of a transaxle include the differential and the transmission. The differential is essential for allowing the outside wheels to turn faster than the inside wheels during a turn, while the transmission is crucial for controlling the vehicle's speed and torque through gear changes.

In this context, the correct choice highlights both the transmission and the output shaft, where the output shaft connects the transaxle to the drive axles, conveying power from the transaxle to the wheels. Thus, these components function together to effectively manage power distribution and enable the vehicle's movement.
