Thank you. Was this truck in a flood or just too deep of a puddle? Sound's like every connector may need to be checked. All trans connectors will need to be cleaned and check due to looking for P or N safety issue. Water can cause big problems. Water conducts and can cause things to ground out, burning up components. Good hunting, keep us posted.

truck has a leak from back glass so its only inside i suspect TCM has issue as P/N switch is not working as well looking to get a factory diagram as mitchell1 diagram doesn't look right for this truck .

Another thing could be the P/N switch cable/linkage could be slightly out of range and contacts not lining up. I've got wiring diagram for my rig if you'd think would help. Not sure what's different 2011 - 2014?
