With the engine running and the transmission in neutral with the clutch engaged, which of the following components is NOT rotating?

The output shaft is not rotating when the engine is running and the transmission is in neutral with the clutch engaged. In this scenario, the engine is supplying power, but because the transmission is in neutral, the input shaft, which connects directly to the engine, rotates freely without engaging the drivetrain components.

The input shaft turns due to the engine's power delivery. The counter shaft, which interacts with the input shaft to provide gear ratios, will also rotate as a result of the input shaft's movement. The drive shaft, which connects the transmission to the wheels, is only affected when the output shaft is receiving torque from the transmission. Since the transmission is in neutral, there is no torque transferred to the output shaft, meaning it remains stationary.

Therefore, the output shaft, which is responsible for delivering power to the wheels, does not rotate in this specific condition. The other components are still in motion because the engine is supplying rotational force, illustrating how the mechanism of the transmission operates when disengaged from the drive system.
