Not the same powertrain but hopefully some numbers as general comparison. In my '09 Silverado (with tow package, tranny cooler), 150s to 160s around town and not towing.

I had a '14 Silverado LT / work truck configuration as a loaner when mine was in the shop a year ago. No tow package or tranny cooler and it ran 195 to 205 around town.
You can find tables with reductions in tranny fluid life as temps increase, seems it didn't really start to fall off until upwards of 250 degrees. I'll have to search again, if i can find, will post a link.
Hope this helps.
