2014 A6 warm trans flaring
 

My 2014 Silverado will flare 250 RPM between gears when the A6 transmission is above 160F and RPM is about 2K. Feels worse the hotter the trans temp and the more I have loaded in the truck. Dealer trans guy agrees on the issue but says it is normal...I don't buy it. Doesn't do it cold or if I accelerate above 3K RPM or in tow haul mode when shifts points are higher.
