Aaaaarrrgggghhhhh!!!!!

hey guys.....for a year, my car has hesitated/surged/and now, slipped. i finally brought it in and they put on a new TPS, which does seem to have fixed the hesitation/surging. BUT on way home form shop, car continued to slip badly and hunt for the correct gear...tranny fluid new, filter new, VSS new, what now???? (besides a pair of matches...)

What year do you have? I have a spare A/T out of a 93 3 cyl. It is good and you can have it for free if you pick it up on Kansas City. I do not want to ship it.
