Hey Al, Welcome to the club and good luck with the new car.
In the first place, you had better tell your loving wife that if she expects to have peace in the family that she should let you drive her car. :D
My suggestion is to wait awhile, and if the shifting thing really bothers you, then have the dealer check if the newest transmission upgrade was done to your car before it was delivered to you. There is the possibility that it was never done. The dealer has ways of knowing this cars history. As the old saying goes, "Don't look a gift horse in the mouth". :)
