No I got it, just was suggesting things so that you could better think of possable problems. If you have power and it starts then great.
First the ECU has to recive a break engage before it will alow the shifter to move from park. This could be a problem with the break sensor. Not sure about other ECU requirements (haven't tried them). IE. Rear window closed. It is more likely that Smrt4her's post is the solution and the switch needs lubracating or the shift unit needs replacement.
