Pressure Control (PC) Solenoid 2 Trim
WARNING: This page is about a different car, the 2008 GMC Yukon and 2008 Chevrolet Tahoe. However, it is still accessible from the selected car via links, so may be relevant.
The PC solenoid 2 trim is energized (ON) allowing actuator feed limit fluid to enter the PCS 2 signal circuit. PCS 2 signal fluid is then routed through orifice #38 to the hybrid direct, 2-3-4 clutch regulator valve.
