First off its not the IWE as far as i can tell. (passed all tests)
It's not Wastegates.
No heat shields are loose.
The trans is brand new from Tier One Transmissions (They say its not trans related)

Sounds like rough marbles being swung in circles in a can.

Will not happen in Neutral and revved.
Will not make the sound when in gear on a rack.

It does not appear to increase with rotational speed.



I cant narrow it down. I am the only mechanically inclined person I know and I don't have any friends. :p
Local shop can't figure it out either.

Has anyone came across this?
