Do you have the display where you see the PRND all the time, and they change color to indicate the current gear position? Is the "R" red, but the remaining letters (P, N, and D) are all GREEN (not white)? If so, then you have a Trans Range Sensor (TRS) fault (P0706), which means that the PCM is getting a bad (invalid) signal from the TRS (inside the trans). Your PRND letters should normally be WHITE when they are "off." For example, in Park the "P" should be green, but R, N, and D should all be white. In Reverse, "R" should be red but the others should be white.

Whenever you have an invalid TRS reading, the display illuminates "all" the positions (turns them all to their "on" color). Since R is red and the others are green when "on," it looks like the trans is in Reverse. But actually, it is indicating an error (all "on") condition.

The TRS has 5 wires (each connected to a pin on the sensor, which runs against a code plate in the trans). Usually, P0706 indicates a problem with one of those wires (bad connection, broken wire, etc.). Do you get the "all" indication in every PRND position? Is there any position that is OK? Does the trans still actually operate OK? (it should). If you'll tell me which position(s) (if any) are OK, maybe we can figure out which pin(s) / wire(s) are bad.

This could be a shift cable adjustment issue. I have worked on a '12 and had the same issue.
