Well I got a 93 f250 250,000 miles. And its since I got it its always had some stupid trans issues but after owning it a while I finally pulled the codes and I get 628 excessive tq clutch slippage 617 trans shift failure..? And 634 park/neutral ciruit failure. Any ideas whats what? For the first time today it cut off when going from reverse to drive and when I shift it from those the whole truck jumps I topped the fluid off.. not literally. And I pulled another solenoid pack from a doaner truck so im stumped. Im already preparing the worse of buying a whole new trans and tq but if I dont need to im not going to. Thanks everyone. Id appreciate it!! Oh and when u get going. It runs beautifully just bucks at really low speeds from a stop and shifts at high rpms from 1to2 and rarely 2 to 3
