2001 F450/6.8. The trim ring is missing on the shift lever switch and the switch doesn't seem to light up or take the truck out of overdrive when pressed.
Truck shifts just fine in all other aspects. Fuses all appear to be good. Any ideas?

 

You need a new stalk/OD lockout button.

 

Maybe a winter project. A couple of more jobs before the truck is done for the season. Thanks!
