Update 7 months later. Valve was supposedly shipped in October, but before it even got to dealership they decided it was now the transmission. Called GM complain number and they mention possible buy back. That got denied afterb3 weeks then finally 2 weeks later a transmission arrived at dealership. They say I'll have it in a few days. We'll see. So trucks been sitting 7 months while the ethanol is breaking down and tires probably have flat spots. Apparently there's some sort of compensation in the works. We'll see what that's all about.

I'm waiting over 4 months with truck at dealership for the valvebody issue. No end in sight.

Good call on that

Engine light on and random slow shifts

I searched around the forum but didn't find any info if it's already being discussed. Apparently, there is a problem with the valve bodies and no one has a clue when it will be resolved. My '24 2500 with 26k miles has been in the shop for 3 months now. The problem occured very shortly after the trucks crash detection braking system activated but it seems it's a well known issue.
