So I put a used competition clutch in my car yesterday

fired it up no bad noises. as car ran it sounded like "knocking coming from the transmission

went and put the clutch in and loud grinding and clicking noise , I'm reading people say the clutches make noise but this doesn't sound right to me.

want some input before I pull this tranny.


here's a video u can hear the sound when the clutch is engaged

 

Normal sound from the intermediate plates.

 

Took it apart and clutch was fine

But turns out the throw out bearing tab was broken which was the knocking sound !!
