For the sake of discussion...
Talking with a buddy about buying an 05’ 8.1/Allison truck. I shared my only experience with an Allison which is this:
03 Duramax (LLY), towing a TJ to Harlan. In Tow mode, if I was going down hill and got on the brake just a little to slow down and I just rode the brake for a little to maintain speed the Trans would gear down, which I know it’s supposed to do. But several times it geared down to the point of red lining the truck. Since I was unfamiliar with this, it scared me and I didn’t want to hurt the truck so I would give it gas and it just redlined it more, so I’d scramble to get it out of tow mode.
My question is:
(1) was it ok to rev that hard?
(2) Was it my fought for “riding the brake” like I was?
(3) does the Allison behind the 8.1 gas engine have the same characteristics as behind the Duramax?
