Theory of Operation

WARNING: This page is about a different car, the 2011 RAM Pickup and 2011 RAM Cab & Chassis. However, it is still accessible from the selected car via links, so may be relevant.

The Transmission Control Module (TCM) verifies the operation of the Shift (On/Off) Valve 2 by monitoring the Pressure Switch 4. If a fault is detected, the transmission will go into limp in mode, the Torque Converter Clutch (TCC) will be disabled, the limp in gear will vary based on the current gear and other conditions, and the MIL will be illuminated.
