I used cruise on all four of my Cummins Rams. My '98 12v was a 5spd/4.10 so it ran 24-2500rpm all day every day at 68=70mph towing or not. No downshift needed or possible. It was a noisy beast. The '01.5 and '03 were just a matter of momentarily stepping on the loud peddle to cause a downshift at the bottom of the hills so it was already in it's power band. Same with my '05 Hemi powered Ram and even my lowly 5.4L F250. If I were deaf and didn't have a tach, I wouldn't know the difference. Cringe is not an engine weakness or transmission problem. :B
