R Position (Reverse Range)

Forward clutch: released
Reverse brake: engaged
Start clutch: engaged
Hydraulic pressure is applied to the reverse brake and the start clutch, and the planetary carrier locks with the reverse brake.
The sun gear drives the pinion gears to rotate, and the pinion gears drive the ring gear in the opposite direction from the rotation direction of the sun gear.
The ring gear drives the drive pulley shaft via the forward clutch drum, and drive pulley shaft drives the driven pulley shaft linked by the steel belt.
The driven pulley shaft drives the secondary drive gear via the start clutch.
Power is transmitted to the secondary driven gear and final drive gear, which in turn drives the final driven gear.
