Clutch Pressure Control
The PCM actuates A/T clutch pressure control solenoid valves A, B, and C to control the clutch pressure. When shifting between lower and higher gears, the clutch pressure regulated by A/T clutch pressure control solenoid valves A, B, and C engage and disengage the clutch smoothly.
The PCM receives input signals from the various sensors and switches, processes data, and outputs a current to A/T clutch pressure control solenoid valves A, B, and C.
