I'm also currently in the process of trading in my 2019 Colorado for a huge loss. I've only had it a few months and it only has 34k miles, but I've already sank so much into the transmission and it's still not fixed so I'm taking my losses now. I will never trust the 8l45 transmission, and I will likely never buy Chevrolet again. I loved my first gen Colorado so I decided to take a chance on the second gens. Save yourself, don't do it!
