But i have a chattering sound while in neutral and in gear but off the throttle, i put in a new tob but still doing it, and also put in a entire new trans, racing grade built its a quaife limited slip differential, had it shipped from England idk what it can be, any ideas..

I've seen the springs inside the clutch disc come loose and make a weird chattering/rattling sound. could you get a video of the noise?

it's on and off while im not moving, but when i push in the clutch it goes away, also while im driving and its in gear but rolling with my foot off the gas it does it. But again if i push in the clutch the rpms go down like normal and the sound stops

That honestly sounds like a tob to me still. Just cuz its new doesn't mean its good.

Yea i had it a a shop and they did the work, they told me nothing was wrong but i just don't believe it, it did it before the new tob and trans, but still doing it, is there a specific type of tob i need for the power or is stock good to get again

Well its all depending on the clutch spring pressure and torque ratings.

You said the shop that did the work said nothing was wrong with it? Ask them if that is true than why don't they make that noise from the factory...
