Hey guys no one can figure out my problem my 2003 mustang gt has the 4r70w keeps giving me problems don't know if it is my tranny or not when ever I'm driving and as soon as I shift into 4th gear the car vibrates and hums when below 45 anything above that you don't notice and when I'm coming to a stop when it downshifts to 1st gear it whines a lot coming to a stop when I put it into neutral and when I put it into drive it will jerk foward never did it when I first bought it no one can figure out the problem we had my rear end seals all replaced and that quieted it down for a bit but came back any help would be appreciated sounds like the tranny is bad but the rear end is really throwing me off
