2016 Chevrolet Impala Power Train

Between 25mph and 35mph transmission will " lose " gearing and start revving when I'm stuck in traffic, causing a safety concern/risk. Have to stop the car completely and let her cool down below half operating temp for the transmission to rekick into gear. Happens Everytime after driving through cities, ATF has a slight gray tinge to it but no burning smell

Transmission failure 2nd time in car at 101,000 miles
