Q27C Pressure Control Solenoid Valve 3
WARNING: This page is about a different car, the 2024 Chevrolet Equinox. However, it is still accessible from the selected car via links, so may be relevant.
Pressure control solenoid valve 3 is a normally high pressure control solenoid valve. The solenoid valve regulates and directs fluid pressure to the R1/4-5-6 regulator valve. Increasing pressure to the R1/4-5-6 regulator valve increases pressure to the low and reverse clutch or the 4-5-6 clutch, depending on the position of the clutch select valve.
