Handled thank you

 

I have just had the gauges problem on my excursion, replaced the shift lever (twice) replaced the ignition feed switch fuse which had blown, everything works again now but my overdrive switch, it is lit up od off, I have tried pushing button will not go off, tested all other fuses, actually tested them not just looked at transmission shifts perfect as before just will not go into od? Wire from od button did have bear spot that's why I changed it, tried second new shifter thinking first new one was bad, any suggestions? not a Ford expert or mechanic but kinda handy, about to pull remaining hair out, worked perfectly before, any help or suggestions greatly appreciated.

 

From time to time
when driving...... as the tranny shifts..
I get a whoopi cushion fart like noise.
a quick 2 second fart noise
aro6nd 2nd to third gear shift
Sounds like on the drivers side
truck is well cared for by a hobby mechanic
but runs great and looks nice
thanks would like to fix before it turn worst

 

Thanks for the info. I was able to find the short right where you said it would be. Saved me a lot of time.
