Hello all. I have a 2020 Chevy 2500 Express work van. Today a message came up on the dash that said "transmission hot idle engine". It shifted funny 1 time when i pulled out from a traffic light, then 15 mins later wouldn't shift out of low gear. Finished my service calls then drove 35 mins home, no shifting issues, but message remained on. It did not throw a code. Any body had issues like this?
