Your overdrive band (aka 4th gear) in the transmission is burnt or glazed. Time to start saving for a transmission rebuild. In replacing just this band, your best bet is to replace all the internal bands, seals, while you have it apart, hence a rebuild. I think you can lock out the OD on your vehicle in the meantime?

I did not have the overdrive plugged into the transmission correctly when I installed it and drove the truck for atleast 8 miles. Is the transmission destroyed?
