Theory Of Operation

WARNING: This page is about a different car, the 2013 Jeep Patriot and 2013 Jeep Compass. However, it is still accessible from the selected car via links, so may be relevant.

The Transmission Control Module (TCM) regulates the secondary pressure by pulsing the secondary pressure solenoid. The TCM monitors the secondary pressure solenoid voltage and current draw during operation.
