My clutch never chattered before, Its a spec stage 4.. I blew my tranny up and just put my new one in today.. Went to drive it and it feels like it chatters more and it vibrates a little as im letting the clutch out and down shifting.. any ideas what i could have done??? I cleaned the Flywheel with mineral spirits and wiped it clean.. the clutch and everything else I left alone...

 

Yea i figured it out.. Shimmed the tranny with too small of washers.. owell.. fixed now..
