Circuit Description
WARNING: This page is about a different car, the 2003 Saturn Vue and 2002 Saturn Vue. However, it is still accessible from the selected car via links, so may be relevant.
The TCM uses the line PC solenoid to control the transmission line pressure. The TCM compares various engine and transaxle inputs to determine the line pressure appropriate for a given load. The TCM then regulates the pressure by applying a varying current to the line PC solenoid. The applied current varies from 0.1 amp for maximum pressure to 1.1 amps for minimum pressure. The TCM monitors the current and when a continuous open or short to voltage is detected P0960 sets.
