NB RS vibration in shifter 4th and 6th
 

Hello folks,

I test drove a low mileage NB yesterday but there was a pronounced vibration transmitted to the gear stick in 4th and 6th but not at all in 5th.
Worse under acceleration.
5th had a noticeable metallic bearing sound under acceleration but not deceleration. No other gears presented with this issue. Also the 3rd synchro was starting to crunch.

Has anyone else seen this symptom set before?
