P1776 is a transmission fault code. It is for Solenoid Switch Valve Latched in Low Reverse Position. Solenoid packs were a problem that would set that code in these model cars, but it could be a valve body also. I've replaced both for this code..depends on what set the code. I'd make a trip to a Dodge dealership for a proper diagnosis.
