Exact same thing I was thinking. I am one of those that owns the problematic initial 8 speed transmissions. I also had a 2009 Pontiac G8 that had the horrible flares between shifts that required an aftermarket TCM tune. It could be just me, but I don't exactly trust GM's state of the art transmissions.The 10-speed would make me a little nervous. It's taken a long time for manufacturers to get the programming right on the 8-speeds. I'm pretty happy with my Yukon 8-speed, but my previous Infiniti G37 was never right, despite 2 programming updates to the transmission.
