Default Vibration in 6th on decel

Car has a vibration during decel around 70-60ish.

About the car:
02 WS6
Strange S60 w/ 4.30 gears
Strange chromoly driveshaft (balanced 3 times)
UMI Full length adjustable torque arm
UMI T/A Relocation kit
UMI Poly/Poly lower control arms
Poly motor mounts
Rubber tranny mount

Kind of baffled with this one because if 6th gear is bad typically 5th will be as well.

Any ideas?

Could the clutch be slipping/chattering? Clutch wear typically starts to show in the OD gears since the TQ required to turn the inputshaft is so much greater in those gears.

Clutch is a Tex OZ700 and relatively new (~4k miles). Also have the TicK Master along with a new slave.

It's an interesting thought...so you don't think it's internal to transmission?

Tranny was rebuilt approx. ~2k miles ago. Vibration started within the last several hundred miles.
