IDK if there is more computer crap in the 900's or if they took lazy days, but my 07 has had more issues in the last 4 months than all of my other trucks combined, my silverado needed a new tranny but got a built 4l60E and im good to go. I knew it was comming, slipped from 1-2 and took 5 seconds to shift from reverse to drive, but its a fantastic truck now, no issues, seats are more comfortable and I have more leg room. I still like the yukon, but im just kinda surprised, It may be how I treat it too, but I treated my 06 the same and it took it like a champ. Same with my 03. 07 It cries. :lol: But the dealer fixed it all and it seems to be fine now and has been for about 5k miles, just got a synthetic oil change and it runs great, still wish I had kept my 06 insted of trading it. 16k was worth more to me than the dealer. But it worked how it should have.
