Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.

The gearbox transfers engine torque to the propeller shaft. The input shaft is separate from the output shaft. The multi-plate clutch in the coupling must be engaged to transfer torque to the rear axle. The inner and outer wet multi-plate clutch are the transfer point between the input and output shafts.
The sinusoidal cam disc rotates at the same speed as the propeller shaft. The annular piston rollers act on the cam disc to press the annular piston in and out. This creates an oil pressure which affects the operating piston, which in term engages the multi-plate clutch unit.
