I am having a bit of an issue with my new to me 2002 F350 V10 Ford, I have noticed a few times in the when taking off (first time after being parked)the truck will not shift into over drive unless I cycle the button on the shifter, after that the OD seems to work fine for the rest of the trip. Second thing I noticed is the "OD" light on the end of the shifter will come on at times (indicating the OD is off) even when the truck is in over drive, wiggling the shifter makes the light go out and the truck will not change gears.

Would a new gear shifter fix this as it is a bit sloppy?

Thanks, Paul

 

These trucks tend to wear the insulation off the wires going up into the shifter. They start shoring to ground right at the base of the shifter. That is not too bad to fix. Sounds like you have intermittent ground on the wire coming from the switch to the ECU. I had the opposite problem - hot wire was grounding and this popped a fuse on my truck.

 

Thanks for the info, I will take a look at the wiring tonight.

Fire bird, you were spot on, pulled the cover off and sure enough the wires were rubbed through the rubber coating at the base of the shifter, put some tape on the bare wires for now. I am going to order a new shifter and pin tomorrow to kill two birds with one stone.

Thanks, Paul
