Overdrive will not work! 97 F350 Auto 7.3 Diesel
I need some help here. I have a 1997 Ford F350 7.3 w/ Automatic transmission. My truck will not go into overdrive. The light on the shifter is stuck to off and is lit up.
I did replace the shifter and the button from OEM Ford parts and it did not work. I look at all the wiring and it all looks good. If I remove the button from the shifter and use a wire and jump the ground it will shift into overdrive. CRAZY!! You would think it would be the button but its not.
Any ideas here? Driving me CRAZY!!! Appreciate any help you can give.
