    Wow... the amount of traffic on this group has dramatically decreased over
    the last year. Incredible... Anyway, I'll just hope I get a reply, I have no
    other avenues...

    I had problems with my auto transmission on my 94 SC1. Took it to AAMCO, got
    a used tranny put in. Just took it out of the shop. I am having a huge
    problem with it... It shifts VERY hard from 1st to 2nd...with a bang. This
    couldn't be good for the transmission.

    I haven't called the AAMCO people about it yet, but, before I left, he said
    the transmission seemed to be good on the road test, and that the car's
    computer would need to be "retrained" in the next couple of weeks, and for
    me to come back and get it checked (free) to see if it is all OK.

    My question is: Is the hard shifting just part of the fact that this is a
    different transmission in another car? Will the comptuer eventually "learn",
    and stop the hard shifting? Or is this a defective transmission?

    I'm praying it's not defective... if it is, I have to pay all the labour all
    over again...

    He also said that on overdrive cars, it is best to just keep it in overdrive
    (Performance/PERF) mode all the time. Should I?

    Please help...Thanks.

    That is correct. The computer will eventually get use to the shifting
    patterns of the transmission and this hard shifting will stop.
    Another thing you could do is to got to the dealer and get him to reprogram
    the computer.
    I had my changed in my 95. I was told it would be shifting hard, and it was.
    The Saturn dealer told me to pop by, he hooked up the handheld computer,
    changed some codes, and it was smooth sailing from there.
