Just wondering if others are having similar problems. I have a 2020 Sierra SLT with the 10 speed transmission, truck has about 2500 miles on it. Recently it started hard shifting at low speeds into gears. It threw a check engine light and go so bad that it was banging in and out of gear from Park to Reverse when I shifted. I took it to my local dealer, they kept it 2 nights and apparently called in and reprogrammed it and did a transmission relearn and gave it back to me. They said the oil wasn't burnt so they were told not to change it. Within 2 hours of picking it up it was starting to hard shift on me again, although less extreme. I just went out to my driveway to pull it in the garage. When I put it in drive it banged around a bit and appears to be in 5th or 6th gear....very lethargic and you have to give it quite a bit of gas to get it in the garage. Obviously frustrated with these problems on a like new truck...just curious if others have seen this?
