Code P1886 Buick Description

The 3-2 Shift Solenoid Valve Assembly (3-2 SS Valve Assy.) Is a normally-closed, 3-port, on/off device that controls the 3-2 downshift. The solenoid attaches to the control valve body within the transmission. The Vehicle Control Module (VCM) controls the solenoid by providing a ground path on circuit. During a 3-2 downshift, the 2-4 band applies as the 3-4 clutch releases. The VCM varies the timing between the 3-4 clutch release and the 2-4 band apply depending on the vehicle speed and the throttle position.
