So, I finally have 700 babied miles on my new 2007 GT and decide to wind it up to 6000 rpm and do a quick shift into second (Not a speed shift or flat shift, but fast enough to break the tires loose going into second). It goes into second just fine, but when I let the clutch out and got back on the power, I hear a very loud metal noise, almost like a loud crack in the back or under the car. But, nothing changed on the car. It made me nervous, but I tried it twice again, with no problem whatsoever. Does anyone have any ideas on this?? Maybe something got hurt or something snapped into place.
