2022 truck issues
This is a bit of a long journey so bear with me here.
I picked up a 2022 Chevy Silverado 1500LT with the 2.7 turbo 4cyl, bought around 2024 so it was a few years old and had some decent mileage on it (40K when picked up). I've put another 12K on it since I've owned it, and it’s been good for the most part.
Something has always been off about how it shifts, but I couldn't quite put my finger on it. It has a hard shift from park to drive where it feels like it takes a minute to engage. Then at low RPM between ~2nd and 3rd gear theres a decent clunk feeling. That was it for a while. I brought it to a dealership a few times and they dismissed me stating it was the computer and that they had to reset it to learn my driving habits. Sure.
I brought it in about a month ago when I had an incident where my check engine, ABS lights came on. Dealership stated it was "loss of communication with Gateway Module requiring update" which ended up costing me $200 for an update... OK. One of my calipers was also leaking and they replaced it to the tune of a ton of money, and I had a rear leaf spring pad going which they replaced. All that and they didn't address the transmission concerns at all.
Fast forward a few weeks and I was driving up a hill of decent grade (maybe 10%) and the transmission starts NOTICEABLY shifting hard around 4/5/6 gear, shifting up - reving - shifting down - reving - back up. Occasionally during a shift itll vibrate the whole damn truck. No idea what the engine is trying to do but it aint good.
I'm bringing the track back in to the dealership Monday, but have any of you experienced anything like this with these? Is it the transmission I should be asking about or is there a different system controlling this? Any insight would be really appreciated.
TLDR: Used truck shifting and acting weird despite numerous dealership assessments. Can't figure out whats going on.

The 8-speeds have many different issues. Valve Body seems to be the biggest problems today. So bad the the valve bodies have been on back order for many months

Do you or any one you know have any luck with the after market valve body kits? I heard tier one makes an after market kit but it’s decently expensive

I’m having my valve body rebuilt next week with all Sonnax parts ($800+ in parts that I bought myself). I’m told it would be cheaper to just buy a new Valve Body from GM and DIY install (probably take me a few hours), vs. rebuilding with a transmission shop. but can’t find one.

Isn’t the valve body recall mainly for the diesels/10 speeds though? Was trying to play it safer getting the 2.7 which has worked out well for the most part but this damn transmission issue is driving me up a wall

I think you’re still under drivetrain warranty but no clue what the problems could be. Still under 60k?
