Thanks for the advice. The only thing that worries me about it is that I hadn't heard it or noticed it before. It is possible that it was always happening too, so i'm not ruling that out. But the last time I heard a noise that seemed off I took it in to the dealership when I had 7K miles on it and they replaced the transmission, so I am always skeptical...
