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 3 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 3 on the high side driver 1 circuit. The transmission control module controls the clutch pressure control solenoid 3 through the clutch pressure control solenoid 3 control circuit. The normally high clutch pressure control solenoid 3 controls fluid to the hybrid low, 1-2 and the 4th clutch assemblies when commanded ON and exhausts fluid when commanded OFF. The clutch pressure control solenoid 3 regulates the transmission fluid pressure to the hybrid low, 1-2 and the 4th clutch assemblies.
