Theory Of Operation

WARNING: This page is about a different car, the 2016 Dodge Journey and 2015 Dodge Journey. However, it is still accessible from the selected car via links, so may be relevant.

The Transmission Control system uses three pressure switches to monitor the fluid pressure in the L/R, 2/4, and OD elements. The pressure switches are continuously monitored for the correct states in each gear. If the Transmission Control System detects an invalid OD pressure switch state, normal operation will continue if no other codes are present. Transmission Control System will ignore the invalid OD pressure switch state. Limp-in condition will only occur if DTC P0871 is present with a DTC P0706.
