Whine/vibration on fast decel shift

[SeeCoryRun]

Ive noticed over the last couple of days if I shift from 4th to 3rd at speed, as if to slow for a light or downshift for a turn, there is and odd whine/vibration. It may be in my head but i felt almost twice as if I could feel it in the clutch pedal as well. Is there a know issue with maybe the throwout bearing or posibly the input shaft bearing? It only does is on a high rpm decel. Or is this normal????

thx, Cory
