    Finding a low mileage 98-02 4t65e around here isn't working out to great for me. Can I put a newer 03+ 4t65e transmission in a 2001 grand prix that does NOT have a supercharger?

    I read about re-pinning the connector and using the old transmission range sensor from my car and it would work.

    Just looking for some advise on which transmission I can put into this car.

    I put an 03 GTP trans into my 99 Regal.

    I used the old Trans Range Switch, and had to use a 2003 PCM (Hardware) with a 2003 Cal installed. No wiring changes required. Worked great for me, and the car's still running around someplace.
