hey, this isnt for a mustang but i need some help with my winter beater and i think it would apply to all automatic transmissions. heres my problem...its an 00 v6 crapmaro. When driving -normal or getting on it- when it shifts form 1st to 2nd i get a bang, like it slams u into the seat and then after that its fine.....i remember it did this about 4-5 months ago and then stopped...now it just started again...im gonna go drive now and see what happens...thanks for any help on this non stang question.
