    Recently took my '02 SC2 AUTOMATIC (32K miles) into the shop to have the
    motor mounts replaced. Shop said diagnostics showd that my transmission
    throttle body was failing testing and needed to be replaced. Warranty
    covered it, so I ok'ed the repair in good faith. I now am wondering if I
    made a big mistake.

    Seems that the tranny just wont learn how to shift smoothly no matter what I
    try. I have had techs reset the transmission variables twice already, been
    driving the car like a granny and also followed the suggested learning break
    in procedures (upshifting / downshifting) per the Saturn tech manual.

    At lower speeds, around 15-20 mph (when going from a stop sign or traffic
    light) at approx 2K RPM, the tranny feels like it is "slipping" then the
    next shift feels like I am being tapped from behind by another car. Not
    smooth or enjoyable.

    I didnt have this before they changed the Tranny TB, perhaps the part ehy
    installed is bad? Or does it take an extra-long time for the transmission to
    learn how to behave?

    just to not throw anybody off, the techs referred to it as the transmission
    throttle body, I call it the valve body.

    ^There's the problem right there. I've never called it a throttle body
    as it does not control the throttle. I'll re-install my eSI disk this
    weekend and see what information I can give you. I cant remember if
    there were any checkballs with these.
