My build date is : Feb 2013.......It seems that perhaps the cars built after the mid-year model refresh don't have the "earlier" problems.
My RS was one of the first one's off the line to hit Pennsylvania, in November of last year.
I don't think your hypothesis is proven.
Well yes there isn't enough data to prove anything yet, but you do have a 6t40e instead of a manual......I would be shocked if you were having problems with it beyond the normal automatic transmission behaviors.
