I have the same problem, with my tranny heating up for no reason that I can find? I have an '05 2500HD, and and I tow my travel trailer with it, and ever had any issues. Then last summer it just started heating up to the the range it would be at when I tow, but that would only be while driving arouund town, or to and from work. I think it may be something a shop did; I had the u-joints replaced, and it was only after then that is started happening. Could there have been something with the u-joints not being properly installed that would lead to the tranny getting hot?
