Code P2727 2014 GMC Sierra Description

The pressure control solenoid 5 is part of the control solenoid valve assembly which has no serviceable parts. The normally low-pressure control solenoid 5 regulates and directs oil pressure to the 1-2-3-4 clutch regulator valve and 1-2-3-4 clutch boost valve. Increasing pressure control solenoid 5 pressure increases pressure to the 1-2-3-4 clutch. The Transmission Control Module varies the current to the pressure control solenoid 5 through a low-side driver. Increasing the current to pressure control solenoid 5 increases oil pressure by closing OFF the solenoid exhaust port. Decreasing the current to pressure control solenoid 5 decreases oil pressure by opening the exhaust port. Pressure control solenoid 5 power is supplied by the Transmission Control Module through a high side driver. The high-side driver protects the circuit and components from excessive current flow. If excessive current flow is detected, the high side driver will turn OFF. When the fault is corrected, the high-side driver will reset.
