So my transmission recently went so i got a new one rebuilt by vw with an lsd and all and also upgraded to a 210mm sachs clutch and i get it all together, shifts nicely into every gear but will not engage and will make a chattering noise when the clutch is disengaged.. Can anyone tell me whats going on here im lost and kind of pissed, i know i put everything on right, proper torque specs and all.. Helppp
