I don't remember the numbers but I have the same engine in a 2012 Dodge and when monitoring the trans temp in summer it shows about 2/3s to the hot side with 90 degree temps, 65 mph and probably 235 coolant temps. Am I happy about this, no, am I diligent about watching it, yes. Have I seen it get higher and cause me to either exit the freeway, or take other measures to alleviate the concern, no. If I were exposing the engine to these conditions regularly I would have a meeting with my dealer and resolve my concerns but... BUT the truck seems to resolve itself at the elevated temps and is stable. I will monitor the transmission fluid and change it using the stressed recommendations and my nose. Incidentally 1l243 the Dodge has a menu readout for trans, oil and coolant temps.
