I've let the trans in my yellow dually get up to 220-230 a couple of times, and the effects are showing... getting trans slipping codes if I run it hard, gonna need a rebuild in the future I'm sure. (I would have stopped to let it cool thoes times, aside from the situation keeping me from doing so... loaded truck and trailer, part way up a one mile 18% hill, no pull over spots, and not likely to get the load moving again if I stopped.)
So, keeping an eye on the trans temp and letting it cool down when it hits 200-210 would be a good idea. You're on the edge once you get there... Stop, let it sit in park, idleing, keeps the trans fluid moving thru the cooler.
