Hello, I just joined and am in need of help with my 94 f-150 with e40d trans and EFI, i changed the steering wheel and did not plug up the OD button, but it shifts into over drive at 45 to 55 mph. it stumbles and/or stalls in reverse and 1st gears! how ever it only does this after it warms up. when i 1st start it and it is cold it works fine, it only does this after it gets warmed up. Then when i drive and get to around 50 to 65 mph and just try to maintain those speeds it stumbles much like it has a miss jerking the truck! I just changed the torque converter and trans fluid. fluid is full. Th
