Im my tranny I noticed a tapping noise a when the clutch is released and a slight tremble in the tranny and exaust pipes when at idle. Is that normal....idk probably a stupid question..this is the first muscle car I owned I use to own a prelude...I know these cars are different.

 

No this isn't normal.Everything should be solidly mounted.The tapping noise could be coming from the loose exhaust.

 

This only happens when the car is in neutral and my foot is off the clutch. I just recently got my throw-out bearing replaced. Does this sound serious?
