IMO if the 6L90 with the new programing is anything like the current SS and LT with the adaptive Sport mode ... OMG that thing will be crazy fun to drive. The current A6 trans being adaptive, when you start hammering on the car, the trans acts in kind. It will adjust it's shift patterns based on how you are driving it. The current version I use Sport mode more so that the Drive or Manual modes in my wife's car. Mine is the LS3, so it acts a little different ...
