It still does it on Resist's Altezza, even after the dealer fitted a TRD flywheel & clutch for him.
While the revs that it occurs at are the same, 3200 down to 2800, the pitch has changed to a higher note. I drove his car & mine (standard flywheel) over the same roads one after the other, and it occurs most noticeably when the engine is on over-run down a hill and passing down through those revs.
I was hoping the TRD flywheel would solve it, having just bought one to get rid of the clutch shudder when cold.. :(
