Circuit/System Description

The clutch pressure control solenoid 4 is part of the control solenoid valve assembly and is not serviced separately. The transmission control module supplies 12 volts to the clutch pressure control solenoid 4 through the high side driver 1 circuit. The transmission control module controls the clutch pressure control solenoid 4 through the clutch pressure control solenoid 4 control circuit. The normally low clutch pressure control solenoid 4 flows fluid to the 1-3 clutch when commanded ON and exhausts fluid when commanded OFF. The clutch pressure control solenoid 4 regulates the transmission fluid pressure to the 1-3 clutch.
