Transmission wont shift out of first gear
Stays in limp-in mode, Chrysler vehicles
If you own a Chrysler vehicle and the transmission stays in 1 gear and will not shift, chances are the computer has put it into “limp in” mode. The underlying condition can be an internal fault, a defective solenoid pack,
or a broken wire. Some shops are reporting a broken wire between the transmission control module and the transmission. Sometimes it’s the yellow/light blue wire that activates the drive solenoid in the solenoid pack. If that solenoid can’t activate, the transmission will stay in limp in mode.
Unplug the electrical connectors between the transmission control module (TCM) located on the side of the transaxle and the connector to the solenoid pack on the transaxle. Then conduct continuity tests on each wire. Repair any broken wires.
