Hello, I'm new to this site so I hope this question makes since. I have a 96 f-250 4wd with automatic transmission. I cant get it into overdrive. I have replaced the o.d. button and taken out the shifter handle and checked the wires and they are good. Here is where it gets confusing, I can use a jumper wire to get it into overdrive by holding one end into pin hole #2 and going to pin hole #1 then keeping wire in pin hole #2 move the other end into pin hole #3 then remove the wire completely. It will work until I turn off the truck but once I do, I have to repeat the process to get overdrive. I was thinking P.C.M. ???? any help would be appreciated. Thank You.
