..... At what speed/rpm at WOT on a long uphill grade does "lugging" occur and become detrimental to the engine or transmission?........


I'm not an engineer. But generally on here, the number 2500 rpm in 3rd on an uphill climb is said to be close to the lower limit. Of course you are running a 3.70 so your lugging problem would be a lot different that those of us running 3.07's
