    I just had the hvac control replaced and now the car won't shift gears
    smoothly when the ac is on. the "system" lite on the dash goes on and wont
    go off until I turn the ac and the engine off. sometimes it just doesn't go
    off for a long while. Are they related(AC and the poor shifting)? It is a
    2001. Thanks--Leon

    Chances are it has absolutely nothing to do with your a/c. I'd suspect an
    input or output speed sensor or something similar. You'll be able to find
    out more by checking the diagnostic trouble codes in the engine and trans
    computers.

    Once again, the selectronic shifting is out of whack. Sometimes it only
    stays in 2nd and 3rd. I've had a new sensor put in but every once in a
    while it will kick back to 2nd and 3rd only.Any thoughts?
