Is the transmission oil heat exchanger too weak to protect 10R80 transmission?

I tow a 6500# camper a lot during the summer. This was the first summer with the 2023. I watch my coolant and trans temps (Using Torque Pro) and I don't think I've seen them over 200-205. If they were even close to 215-220, that thing would be getting an aux trans cooler one way or another.
