Which statement is true regarding the components in a transaxle?

The choice indicating that the input shaft is directly influenced by the engine is accurate because the input shaft is the component in a transaxle that connects to the engine's crankshaft. When the engine runs, it generates power that is transmitted to the input shaft, allowing it to rotate. This rotation ultimately influences the gears within the transaxle, which facilitate the transfer of power to the wheels of the vehicle. It forms the critical link in the drivetrain, ensuring that engine power can be effectively utilized for vehicle movement.

In the context of the other statements, the differential does not only operate when turning; it also functions to balance the rotational speeds of the wheels under varying conditions. The output shaft's alignment is not always with the drive wheels — it can be offset in certain designs. Lastly, the main shaft typically rotates and does not remain stationary; it must turn to transmit power through the gears to create the necessary movement.
