On my 96 Ford 7.3 PSD I used to take it off of OD when pulling a good hill, regardless of what Ford said, I had better control of the ET and boost, But on the new truck they say I dont need to take it off Tow-Haul it will downshift when needed, I still take it off auto-(D) Tow-Haul and shift it manually on Tow-Haul with the selector switch, I can judge the sound of the motor quicker then the computer can keeping the Boost and coolant temps down, it seems to run smoother and doesn't sound like, "should I shift or not" for the computer.
But going down hill I will leave it on auto but I still have the option of splitting the gears with the selector switch.
