Circuit/System Description
WARNING: This page is about a different car, the 2009 Pontiac Torrent and 2009 Chevrolet Equinox. However, it is still accessible from the selected car via links, so may be relevant.
The clutch pressure control (PC) solenoid 3 is part of the control solenoid (w/body and TCM) valve assembly and is not serviced separately. The TCM supplies 12 volts to the clutch PC solenoid 3 on the high side driver 2 circuit. The TCM controls the clutch PC solenoid 3 through the clutch PC solenoid 3 control circuit. The normally high clutch PC solenoid 3 flows fluid to the low and reverse clutch and 4-5-6 clutch assemblies when commanded ON and exhausts fluid when commanded OFF. The clutch PC solenoid 3 regulates the transmission fluid pressure to the low and reverse clutch and 4-5-6 clutch assemblies.
