What is your transmission temperature

Wow, this is very interesting. Quite a difference in both rigs and temps. I wonder, has anyone burned up a transmission from high temps when you knew that it was running hot? Both of my rigs that I have mentioned have a factory installed cooler plus the 'in radiator cooler'. I'm not currently planning any mountain towing but will tow to Texas next month. Last summer we drove a lot of mountains on the way to Montana (Glacier NP) but did not tow or have the scan gauge. I wish I would have had the scan gauge then to monitor the temps as we were shifted down a lot in the mountains. More comments welcome!
