ok, i have a 1994 gmc jimmy auto tranny. when i come to a stop with the car in drive there is a vibration, i dont feel it when i am moving only when its in drive and im stoped. i have accually moved it to neutral, while stopped, and the vibration goes away, then i put it back in drive and it comes back so i know its got to do with the transmission. whats going on this is driving me nuts!!!!
