Clutch Pressure Control
The PCM actuates A/T clutch pressure control solenoid valves A, B, C, and D to control the clutch pressure. When shifting between gears or during lock-up, the clutch pressure is regulated by A/T clutch pressure control solenoid valves A, B, C, and D engages and disengages the clutch smoothly. The PCM receives input signals from the various sensors and switches, then the processes data, and outputs current to A/T clutch pressure control solenoid valves A, B, C, and D.
