215* is a little hotter than I like to see the trans get, although not terrible considering the Dex6 fluid is 100% synthetic now. If it runs hotter in the summer when ambient temps are higher I would consider a supplemental trans cooler.
It's normal. GM doesn't consider it too hot until 265deg. Not that cooler aint better, but I think its thermostat at around 200. My 2020 runs close to 200, empty once fully heat soaked.
