Hi guys, I bought a 2023 duramax with 24k miles. I drove it once and it broke down with transmission problems it was diagnosed that it needs a new valve body as well. The dealership is very vague with timelines and such but like a lot of you this truck is for work and I don’t have 3-4 months to make payments on it and not be driving it. Has anyone had experience getting it fixed not by a dealership or selling it for something else? I’m at a loss and very frustrated this is a huge investment to go this bad this quickly. Thank you all for any advice
