P0785 ISUZU Description
The 3-2 Shift Solenoid valve assembly is a normally-closed, and the controls the 3-2 downshift. The Powertrain Control Module (PCM) controls the solenoid by providing a ground path. During a 3-2 downshift, the 2-4 band applies as the 3-4 clutch releases. The PCM varies the timing between the 3-4 clutch release and the 2-4 band apply depending on the vehicle speed and the throttle position.
