N Position
Engine power transmitted from the flywheel drives the input shaft, but hydraulic pressure is not applied to the forward clutch and the reverse brake. Power is not transmitted to the drive pulley shaft. Also hydraulic pressure is not applied to the start clutch
Scheme 287
Scheme 288
- Forward clutch: engage
- Reverse brake: disengage
- Start clutch: engage
- Hydraulic pressure is applied to the forward clutch and the 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 the final drive gear, which in turn drives the final driven gear.
Scheme 289
- Forward clutch: disengage
- Reverse brake: engage
- Start clutch: engage
- 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 planetary pinion gears to rotate, and the planetary pinion gears drive the ring gear in the opposite direction from the rotational direction of the sun gear.
- The ring gear drives the drive pulley shaft via the forward clutch drum, and the 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 the final drive gear, which in turn drives the final driven gear.
The electronic control system consists of the PCM, sensors, switches, and solenoid valves
The PCM receives input signals from sensors, switches, other control units, processes data, and outputs signals for the engine control system and the CVT control system. The CVT control system includes shift control, pulley pressure control, start clutch pressure control, and reverse inhibitor control. The PCM actuates the pulley control solenoid valves to control pulley control valves A and B shifting transmission pulley ratios.
