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 2 is part of the control solenoid valve assembly and is not serviced separately. The clutch pressure control solenoid 2 controls transmission fluid pressure to the hybrid direct, 2-3-4 clutch regulator valve. The transmission control module monitors the transmission fluid pressure switch 3 state, in order to determine function of the clutch pressure control solenoid 2 and the hybrid direct, 2-3-4 clutch regulator valve. When the clutch pressure control solenoid 2 is commanded ON, the transmission fluid pressure switch 3 state should be High. When the clutch pressure control solenoid 2 is commanded Off, the transmission fluid pressure switch 3 parameter state should be Low.
