Mopar Forums - Problem Code P1B14

I have a 2013 Ram 1500, 3.6L V6, 8 Speed Transmission 8HP45. I stopped at a red light and the engine died. I started the engine and turned the shifter to drive, the light over the dial started flashing and the truck didn't move. I put it in reverse and wouldn't move. Had to tow my truck home. I checked the trouble code and it showed P1B14. Dose anyone know how to fix this? I have checked the oil in the transmission, it is full. I did change the oil and filter over 450 mile ago.
