Drove a longbed, tradesman, aisin, 2019 today. I will say not much different with respect to TQ management, I didn't really appreciate much improvement in power but heck my truck is the 930 so Im not sure I would feel 70lbs more. I will say that downshift seems a little faster and reving at idle seems slightly more brisk. I understand the 2019 has a 3.73 rear vs my 3.23 so probably some changes internally to ratios in the aisin?
Bottom line I would not trade up for the extra tq or shifting improvements. Other features in the limited are very nice. Also, sound has never been an issue in my 2017. I know that the 2019 is supposed to be 10db less and I think the tradesman was not much more quite then mine but the salesperson said the limited has more insulation, not sure if thats true but if so then the 2019 limited may be noticeably quieter.
Lastly, I am not sure I like the new dash, I think the center part sticks up higher than mine which is recessed a little, I just feel I can see out better?
Anyway, only went out for a short trip so thats all I could tease out.
