D and L Position (Forward Range)

Forward clutch: engaged
Reverse brake: released
Start clutch: engaged
Hydraulic pressure is applied to the forward clutch and start clutch, and the sun gear drives the forward clutch.
The forward clutch drives the drive pulley shaft, which 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.
