My 2010 Silverado doesn't have an external trans cooler, only the internal trans cooler in the radiator.
Normal driving and not towing its around 170 I think. Towing, it stays between 200 and 210. When I went to PA, there was one very long, very steep hill and it hit 237 and I was only going about 40mph. There were actually a few pickups pulling mud bogers on the side of the road. Looked like they were "cooling off." I slowed down to 35mph after seeing them, but it was still 230ish... My water temp is always at 210 all of the time (towing or not) except on that hill it went to 215 or so.
I think upto 220 is fine, I wouldn't worry about it at 200.
There are many debates about that chart that is floating around vs modern transmissions.
