I have a 2022 GMC Sierra. It has 100,000 km's (60,000 miles) and I went for a transmission flush where they "drop the pan" because that is what I was told it needs according to warranty. Ever since then, it shifts hard and at one point, I got stuck in the snow with it. When that happened the transmission would not shift into reverse or forward for a while. I had to shut the truck off, leave it for a half hour and then go back and start it again. At that point it shifted and I got pulled out. I did buy an extended warranty when I bought the truck so if the transmission ends up braking.....oh well I get a new one.
