Ted Wright is correct, my 2017 Colorado (new) w/ 3.6 8 speed was doing the same thing as stated. And the dealer did exactly what Ted has stated and was the cure to those issues, I did have the dealer do another drain and refill at around 45k miles and the truck now has about 77k miles and so far it's been good. Hope that helps, good luck
