Circuit/System Description

WARNING: This page is about a different car, the 2011 GMC Yukon, 2011 Chevrolet Tahoe, and 2011 Cadillac Escalade. However, it is still accessible from the selected car via links, so may be relevant.

The clutch pressure control solenoid 4 is part of the control solenoid valve assembly and is not serviced separately. The transmission control module (TCM) supplies 12 V to the clutch pressure control solenoid 4 through the high side driver 1 circuit. The TCM controls the 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 Regulator Valve when commanded ON and exhausts fluid when commanded OFF. The 1-3 Clutch Regulator Valve regulates the transmission fluid pressure to the 1-3 clutch.
