I have the Duramx/Ally combo. Have learned two ways for downhill travel. Checked with a mech at a Chev dealer (who owns the same unit as I) told me I was OK doing either. Starting downhill in tow/haul mode gently touch the brake. It will downshift. About 2500 rpm @ 60mph. You can step on the brake again and it will hit red line. He told me it was made to take it. I do not like to do that to an engine. So after the first downshift would take it out of tow/haul. Now you can brake all you want. However remember that tranny has a memory. It still may down shift again. The other way is to push in the button until you get the overdrive lockout light. Not in tow/haul and manually put it in another gear. Someone on the forum told us to go down a hill at the speed you went up. Sure saves on brakes and fear factor.
