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. The fluid I put in it is "Valvoline Max Life full synthetic DEX/MERC, Mercon' LV". oh and about 6 years ago i put in a new solenoid pack. but after warm up, if i pull it down in 1st gear at a dead stop with foot on brake, it stumbles then it will catch back up and stumble again, same in reverse, sometimes it dies. I changed 'IAC' with new one and cleaned body. I looked for air leaks as best I could, but since I,m 69 years old i can't hear that good any more lol. I could not find any. I tried to pull codes with the only tester i have a "INNOVA 3145 Ford Digital Code Reader", it plugs in under the hood. codes I got was 6-10-542-634, then did it again and done the brake an gas flooring and got 225 no knock code and 632 no OD plugged up. I don't know how to pull codes for the transmission! My 1st Q is, will not having the OD plugged up cause this? If not where do I go from here? Thanks for any help
