I have a 96 7.3 that will not come out of drive. You can put the truck in park and reverse and it works but when i take off i have to take it down to first and second to get it to go. And then when you do put it in drive it seems like it has a load. Once i get moving like when im on the highway it aint bad but it wont shift into od. I changed the speed sensor and that didnt change anything. It did this before so i did a tranny sevice and it didnt do i for awhile and now its doing it again. The od light will flash every once in awhile but thats if im hard on it. but un hooking batteries it will reset and be good. any questions??
