    Was on my way home tonight from work and noticed that my truck wasnt shifting into OD. Truck was running at about 2K rpm at 70 mph and it usually runs at about 1800 rpm. I also tried putting the truck into tow/haul mode at highway speed and noticed no change in rpms. Truck has about 193K on it and runs and shifts great. Just no OD.

    Disregard...was about a half qt low on fluid. All is well now.
