I need the 2000 F150 with the 4R70W and the Lightning. Any help would be GREATLY appreciated. TIA!
There is 3 wires missing in the dash harness that controls the auto shifts.
What my tuner did was re-pin the computer and trany plugs and run the 3 wires so we didn't have to swap that harness.
He did the work so I cant explain it much better.
He could probably help you if you call him at work tomorrow and tell him Phil said to call.
We had the same problem last year when he put my 4R100 in.
