Finally got the call my valve body came in! I did open a case with GM about 2 weeks ago and they managed to get one to my dealership. They cant get to it until next Monday the 9th but will post another update on how the truck is feeling and part numbers. Actually got some relief after its been sitting there for roughly 90 days.

Update, has been 57 days since I dropped my vehicle off at the dealership and still no word or ETA and when I asked about a transmission replacement last week they flat out said no GM wants us to replace the part. So I guess the wait continues

My 2024 1500 Sierra with 12,000 miles went in 11/18 for same issue with the valve body and still waiting with no ETA, will let you know if I get an update but doesn't seem like it will be any time soon.

Same problem here on my 2024 GMC sierra 1500 10spd 12,000 miles. On Tuesday morning block away from my hotel check engine light came on and engine power was reduced message. Got it back to my hotel since dealership wasn't open yet and it wouldn't go into park or reverse. Had to put on my emergency parking brake and it sat for 2 hours until they were open. Drove it 3 miles to dealership and it was shifting fine this time including park and reverse. Got a call back on Thursday saying my valve body needs to get replaced but is on backorder. I told them i needed a truck to drive on my job sites and they gave me a loaner thru hertz which was a f150 since dealership didn't have anything available. After reading everyone's experience I really hope it doesn't sit there for 3 months. Do they order the new one that was fixed or should i be worried about getting the original and be back to square one? Will update as I hear from them.
