Thank you so much for your responses. It does make me feel a little better about the 230 temps. And yes it only reached that high for a few minutes. In fact I pulled over because I was afraid of causing damage. I am unsure if I have a transmission cooler. Looks like it may be just what I need to make it run a little cooler. I will definitely look into that.

Hello all, I have a 2020 Silverado 2500 6.4 gas burner. This past weekend while towing our 7500 lbs camper the transmission temperature reached 230 degrees. The tempature outside was around 75 degrees. The road was pretty steep and curvy so I was driving at low speeds, around 35-40 mph. From what I have read online the normal tempature range goes up to 220 degrees and 240 is when you start seeing problems with the fluid degrading. For all of you gearheads is 230 degrees acceptable? When should I start to worry and give it a chance to cool down? and then is, sitting still, idling the best action to take? Thank you so much for your insight, Ivy
