Trans Vibration/grinding at Low RPMS??

Hello all. I have a 2000 f350 with a 6 speed transmission. When I go to pull out to pull out or when I am driving if the RPMs drop below say 1000, I have a grinding/vibration in my trans. I heard this was normal for some clutches, but I did not seem that sounded right. I could not tell you if it is an aftermarket clutch, I just purchased the truck, but it seems to drive great.

Let me know if anyone has any ideas. Thanks a bunch.

It does it even when the clutch is not being used. So say I slow down on a road and the RPM's drop below 1000, it will make that noise, but right when I press the clutch in it goes away.

Could it still be the throwout bearing?
