The 6.2/6 speed tranny in my Yukon Denali offers significantly better performance than the 8.1/4speed in my old 03 2500 Burb.
If your new rig performs better than your old one, is say something was definitely wrong with what you had before.
Stability might be a different story, but that isn't what this thread was originally about.
Either way, I hope you are happy with what you now have.
That is suprising that you like the 6.2 better for towing than the 8.1. Comfort 6.2 all day long but the 8.1 is soo much better for towing. 6th gear in that denali was worthless unless you were on flat ground towing or not. It would not stay in 6th with the cruise on going up and down very very mild hills. I drove it through the rockies to trade it in for the 8.1 and it was searching for a gear the whole time.....no cruise and towing nothing but me. The 8.1 i set on cruise at 75mph and it kicked down a gear one time. By the way i did put a trans cooler on the denali and it helped the trans temp. However the engine still overheated some. Its just not a motor built to tow.....its for speed.
