High Temps when NOT Towing

High Temps when NOT Towing
I didn't know where to put this question so I'll start here. I have a 2019 3.5EB that I take off roading up in the Sierras or California desert. I do not tow anything at the moment, just hauling camping gear.
Much of the time this is slow crawling, in 4WD, even in 4Low. I see the transmission temps rise very quickly to 240+- even with very short uphill 4L situations. I am concerned about this vehicle in regards to
tranny temps, coolant temps and heat soak.
I thought about an upgraded CAC but since there is practically no air passing over it I don't see how that will help in my case.
Has anyone installed additional cooling fans? Any recommendations for my situation? The truck does have the max tow package.
Thanks

That DOES seem high and I can't see that an additional cooler would help at low speeds. These transmissions are designed to operate at about 205 degrees as I recall, and that's where mine stays on the highway when I'm towing or not towing. What are your temperatures on the highway?
If this happens only when doing your off-road activities, I'd say you qualify for the "extreme" transmission use scenario and you should change your transmission fluid frequently.

Thanks guys, The truck runs normally in all other conditions. It does run hotter than what I'm used to, but a twin turbo 10 speed is going to make some heat.
I have found all kinds of answers and solutions for towing issues, But larger intercoolers aren't going to help much with the engine/tranny is working hard and
has no/little airflow going through it.
