have a 94 6.5 td and keeps trowing the dtc 24 at me, replaced the speed sensor made no difference at all.the truck runs fine but will not shift into over drive at times and when it does the service engine soon light comes on.Tried a variety of things none of them worked so far.I hope is not wiring.Any help would be appreciated thanks all:dang:
