Disclaimer:I'm sure you've already tried this but...

Make sure you haven't pressed the "Overdrive" button on the side of the gear selector.

If that's not it then start looking at the switch itself. If it's damaged or the wiring inside is flaky then it might think it's been pressed. After that look at what that wiring does - keeps some part of the AT from shifting into it's final gear. I'd imagine your problem is electric and not mechanical in nature.

Good Luck!
