2011 2SS Hello: I have a question about my car. Since the first miles on the car it seems to have a flutter...(diffilcult to discribe) Flutter in high gear. 6 Speed automatic and once it reaches high gear with no load a fluttering sound emits from the exhaust and the gas pedal feal is not normal. If add or subtract pressure from the pedal the "flutter" goes away.
Manual shifting is much better and by going up the shift pattern and keeping the RPM'S under two thousand and not going into M6 until I reach 60MPH the flutter will go away....Is this something I should be concerned about? I wish I could discribe it better. Thanks for any answer.
