WARNING: This page is about a different car, the 2012 GMC Yukon, 2012 Chevrolet Tahoe, and 2012 Cadillac Escalade. 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 V 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.
