O/D switch not working
Help please!
My 05 Ex V10 no longer shifts out of overdrive (conveniently, 1000 miles after I'm out of the 36k warranty). I have the 4-speed auto with the overdrive off button on the end of the shifter. When I press the button, the truck doesn't downshift, and the light does not come on.
I'd prefer to fix this myself, if possible, but don't know where to begin in the troubleshooting process (what little mechanical knowledge I have is limited to late 60's technology).
Any suggestions would be greatly appreciated.

If this is what happened to you you're lucky, when mine went out, the gauges all went out and the throttle went to idle. Fortunately I was going down a long hill and was able to coast into town. Also fortunate that I still had the engine running, the thought of going down a 12% grade w/o power brakes is scary.
