I experienced transmission problems with this truck at 50000 miles, and had to totally replace it with a new trans out of pocket, not covered by any manufacture warranty. In addition, the check engine light keeps coming on, once you add a bottle of Heet or Engine cleaner into the fuel it goes off, until, fuel gets low and more is added. Then it starts all over again. Truck lugs down on slopes and looses speed, not a pulling type of truck.
