The shifter will move and the correct selection lights up on dash, but car won't move. It has thrown codes p0716, p0721, p0791. The fluid and filter have been replaced, visual inspection of wires and connectors reveal nothing, all fuses are good. It kind of revs up and acts like it wants to move in reverse but it doesn't. Check engine light on but that's only light that has ever appeared.

Hello,

The codes
P0716 Input speed sensor 1 circuit performance
P0721 Output speed sensor circuit performance
P0791 Transfer speed sensor circuit

These codes can get triggered due to a number of reasons. It could be not getting proper signal due to wiring issue, bad sensors, or issue with the powertrain control module (PCM).

See below, I have attached the diagnostics guide for these codes. Follow those processes, as it can help you determine the issue.

Let me know of any questions.
Thank you.
