Roush Ever Heard of Light Grear Rollover?

Over the last couple of months my clutch/transmission on my '05 has become progressively more clunky or loud if the car is in neutral. Once I begin to engage the clutch the sound immediately disappears. It almost sounds like the bearings/bushing on my crank are shot to hell.

Anyway, I took my car to Ford for them to look at and they said there is a Ford SB that says this is normal.

Has anyone experienced this yet?
 
My original t5 used to do it.
Kinda like you can hear it spinning even though the car is not in gear?
I blew up the trans, so i never really had it diagnosed, but my thoughts were also the TOB.
