Thanks Dooner, Power247. To me, the torque in the 3500 clearly makes up for the difference in gearing that was in my 2500 Hemi (3.73). Initial take off in the Hemi was great but then in low end pull it was no comparison to the Cummins. I know that goes without saying but from a roll I can break my tires loose in the 3500. I'm not sure if the Aisin has anything to do with that but I'm telling ya, Its crazy.
