I can't speak for anything but GM, but I have had both gas and Diesel's and each one acted different from the other. My '98 6.5 Turbo Diesel had no engine braking what so ever. My '05 6.0 gas with the 4 speed tranny had none as well. My '07 classic Duramax had a little bit more...but the holdback of the Allison was doing most of the work. In '09 I bought another 6.0 gasser that had the GM 6 speed (non Allison) and if it was in T/H mode, a tap of the brake and it would downshift and feel like it was going to spit out a valve at 6000 rpm. My '13 Duramax has the best of both worlds. A exhaust brake and the downshifting capability of the Allison. If on cruise...it will hold that speed down hill towing or not. If not on cruise it will slow the whole package down with no service brakes if it is under about a 9% grade.
