Do you have the auto 4x4 option on your truck? I just had the motor drive on my transfer case replaced last fall. I back my truck into the garage and several times I would come home and have no reverse. Select 4hi and reverse worked fine. Then other symptoms started like randomly shifting into 4x4 modes on its own and finally going into neutral while traveling down the road. No SERVICE 4WHEEL DRIVE message and no codes stored. Took the dealer a couple days to figure out. Certainly a less expensive repair than a trans rebuild or replace.
