The transmission malfunctioned 4 times in the first 3 weeks of ownership. Once on the way home from the dealer, but I could not return as they were closing when I picked up my new 2026 Silverado 2500HD pick up. It has 2 issues so far since that ride home, 2 times, on separate occasions, I was approaching a red light and slowing down when the light changed while I was in a slow speed, so I accelerated to get to the speed limit, while doing so, the truck hesitated for a couple of seconds then banged into gear. The second time for that same scenario was several days after resulting in the same hesitation and then bang into gear. No warning lights were reveled. I called the local Chevy dealership, as instructed by the dealership I purchased it from was 107 miles away, they gave me an appointment to investigate the problem. Upon arriving, I needed to back up to align my vehicle with the entrance to the service area and my truck would not go into reverse. I tried 2 times shifting from park to reverse and nothing, I put it back into park while still running and went into the service area explaining my new issue, the service writer got a mechanic and he tried shifting into park with no luck. He then shut off the engine, waited about 30 seconds, restarted the engine and shifted into reverse and it worked. They checked for codes and none were present, so they test drove it for about 20 minutes, did not experience either symptom and email GM service assistance and were told to have me come back and they would check the parameters and make sure the software was updated as well as the transmission fluid level and condition. I returned for them to accomplish those tasks and drove home, 2 miles, and had no issues till the trip I was going on today, I warmed up the vehicle as it was only 37 degrees today and when I put it in reverse, it did not engage, so I shifted into drive, it engaged then I put it in reverse and it did finally engage. Now I'm going to renotify the dealership
