We all know that sound when you're taking off in 2nd and the rpm's bog down when there isnt enough throttle...but is that "clunking" feel normal? And does it cause any damage? Also, the clicking/ clunking sound when parked in neutral with the clutch disengaged is incredibly annoying...while the clutch is engaged, its gone...any idea what this is?

 

flywheel chatter.

 

I have a similar problem in third gear from a stop.
