So I noticed a clanking noise the other day while taking off from a stop in first gear. The noise happened when the clutch was just making contact with the flywheel. Sounded like it was coming from the rear of the car. So I tried to diagnose the problem by pushing the clutch pedal to the floor with the car in first gear and letting off the pedal until it started engaging the flywheel then pushing the pedal back down. However, when I did this I thought the whole drive train was going to fall out of the car. It made one hell of a racket and actually shook the car. It literally felt like the whole mess was loose or something. Anybody have any ideas what could be happening down there? I have a 2007 z51 manual with 9,600 miles by the way.
