Code P0778 help needed

The code is for a failure related to the 2/4 brake solenoid. As a starting point I would remove and clean all of the electrical connectors to the transmission and TransControlModule (TCM). If cleaning the connections doesn't resolve the problem and you don't discover any damaged wiring then the next step is removing the solenoid and replacing it.
I recommend going to the jagrepair.com website and download the tech section for the transmission.
