So what do you see on your dash? I think on yours the PRND letters are normally white, but the current gear position displays as green (or red for Reverse). So P and N are OK? Do you have a P0706 fault code?

If no P0706 fault, then I suspect the problem is in the instrument cluster and not the trans. If the trans itself is sending a "bad" (invalid) PRND position code, the dash display should light up ALL the positions (which, because of how the display is set up, looks like Reverse, because P, N, and D are all green but R is red).
