Start Clutch Pressure Control

The hydraulic-controlled start clutch, like a torque converter, controls smooth starting-off and creeping in D, S, L, and R. The PCM inputs signals from the sensor and switches, and actuates the start clutch pressure control valve to regulate the clutch reducing pressure, and the clutch reducing pressure controls the start clutch.
