We were only doing between 25-45 the entire time. Towing around 16500 or so this time.
Temps were fine, power was fine minus the (2) regen cycles in 2 hours.
Before and after the hills, the tranny shifted fine, up and down shifting.
The truck only has about 3200 miles on it, 80-90% of that is towing.

Well with as little miles as you have on the truck, it seems to me that truck hasn't had a chance to "learn" steep grade with your driving. You have have to becareful when your in tow/haul and letting off and on the throttle......if you let off the throttle and your still increasing speed rapidly, the truck will try to downshift to help brake the truck......but we need more info on the truck, like if its stock, what mods if any, where you on and off the brake too....
