What components are contained within a transaxle case?

The transaxle case is designed to house both the transmission and differential within a single unit. This configuration is commonly found in front-wheel-drive vehicles, where space-saving designs are essential.

Having both the transmission and differential in the transaxle allows for efficient power transfer from the engine to the wheels while maintaining a compact layout. The transmission manages gear shifting and power distribution, while the differential allows for the wheels to rotate at different speeds, especially important when turning.

The other options do not accurately reflect the components found within a transaxle. For example, the combination of transmission and engine is incorrect because the engine is a separate component located at the front of the vehicle. The differential and transfer case typically pertain to separate drivetrains in four-wheel-drive or all-wheel-drive vehicles, whereas the engine and drive shaft also do not belong within a transaxle case, as the drive shaft connects to the rear axle or other driveline components outside of the transaxle.
