Just got my 2010 m6 SS earlier this summer it only has 19k miles on it. Today as I was driving I started to notice that my car was sputtering in first as I would take off and I could feel something knocking in the shifter as if every rotation it would do it. I just read that their was an output shaft problem in earlier models of 2010's. Really stumped on this one
