I have had an incident where my 2023 GMC 3500 hd was had left me stranded earler this week. I towed the new truck to a certified dealer and I haven't heard anything since then. They mentioned my transmission will need to be fully replaced because valve body issues of solenoid a,e,f, are stuck open and closed codes on the 10 speed transmission upon researching my trucks history it was manufactured in 2022 and pulled out for sale October 2022 and I have seen. 242454441 special recall the same issues I experienced shudder and engine power reduced and no parking gear or driving. I need help and didnt have any warning of anything about this till now since it was showing my vehicle only had a tailgate issue which GMC didnt help me out when I had to pay for my taillight after firewood flew out with the tailgate opening in Jan 2023 they said it wasnt a known issue then fixed the tailgate but not the taillight so I need help proving my truck belongs with the 242454441 class of recalls because not only does the transmission the exact same as previous models obviously 1000s of others are getting this issue thank you.
I was driving in the high way and the vehicle started having issues and then it completely shut off and wouldn’t drive or anything in the middle of the highway and the dash said it was reducing power.
