RAM 6.4 Ike Gauntlet

I think they do it right. Put it in gear and drive it up the hill and let the pickup manage itself. The more input from the driver the less meaning the test has. It becomes too subjective at that point. I agree manually shifting yields better performance, I notice that my tranny temps are much lower when I control the shift points.

I had a 2015 3500 6.0 and it pulled some crazy heavy loads up some serious grades. I knew it was a strong motor but until I owned one, I never knew what they could actually do. No different than the gas engines from others I am sure. They are very capable engines often overshadowed by the diesels, but still very capable.
