After replacing the 12V battery during a recent cold spell, my car started displaying a P16F1 error code and a 'Service Transmission' message. The shifter is now flashing P N D L, and the car won't shift into drive. The high-voltage battery is fully charged, and the engine starts normally. It seems like there might be an issue with the engine or transmission control module. Has anyone else experienced a similar problem? Any suggestions on how to troubleshoot or fix this issue?
