i just bought this truck, transmission shifts good in all gears, but will not go into overdrive. does anyone here have any clues as to where i might look first? a few times, i went to take off, and it would take off in second gear, and not shift at all. i just disconnect the battery for a while, and it will start shifting again, but still no overdrive. any help will be appreciated. thanks, bgboy

 

I know a friend Of mine had the same problem and it was a fuse that was blown.
I think that everything is electronic so Id check there first...
