The PCM actuates the 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 the A/T clutch pressure control solenoid
valves A, B, and C engages and disengages the clutch smoothly.
The PCM receives input signals from the various sensors and switches, processes data, and outputs a current to the
A/T clutch pressure control solenoid valves A, B, and C.
