Circuit/System Description
WARNING: This page is about a different car, the 2009 GMC Sierra and 2009 Chevrolet Silverado. However, it is still accessible from the selected car via links, so may be relevant.
The clutch pressure control solenoid 5 is part of the control solenoid valve assembly and is not serviced separately. The transmission control module supplies 12 volts to the PC solenoid 5 through the high side driver 1 circuit. The transmission control module controls the clutch pressure control solenoid 5 through the clutch pressure control solenoid 5 control circuit. The normally low clutch pressure control solenoid 5 flows fluid to the actuator feed limit valve when commanded ON and exhausts fluid when commanded OFF. The clutch pressure control solenoid 5 regulates the transmission fluid pressure from the auxiliary transmission fluid pump in order to maintain transmission fluid pressure during electric only and auto-stop modes.
