Theory Of Operation

WARNING: This page is about a different car, the 2009 Dodge Caliber. However, it is still accessible from the selected car via links, so may be relevant.

The Transmission Control Module (TCM) monitors the TCC ON/OFF Solenoid Control signal during normal operation. If the TCC ON/OFF Solenoid status does not match the TCM requested ON/OFF status a DTC will set.
