1-3 Reverse Clutch Releases
WARNING: This page is about a different car, the 2009 Saturn Vue. However, it is still accessible from the selected car via links, so may be relevant.
If the transmission is operating in First gear when an electrical malfunction occurs, the normally closed shift solenoid 2 and the normally low pressure control solenoid 4 trim default to their normal states (OFF) and the 1-3 reverse clutch is released.
