The truck will not shift out of O/D, which this winter I plan to tow a snowmobile trailer. I checked the connectors into the transmission and cleaned them up. Also checked fuse #27...visibly it was not blown, but I replaced it anyway. Still no dice. I also just noticed that my brake indicator light is not working when the e-brake is down. The brake light will come on and test when the truck first starts, so I know the light is working.
