Hi all. My wife and I traded in an 02 Yukon XL for a 2008 Acadia. We actually were looking at new ones, but found a used GMC certified one with all our options except the sun roof. I have been lurking on this forum for a few days and it looks like there are a few things I need to address. The number one thing is the tranny update. I will let everyone know my thoughts on the update once we do it.
