Thread: Transmission grinding while in gear....clutch?

So after replacing my bad rear motor mount the transmission has a grinding sound while I am accelerating in gear. It goes away when I push the clutch in. I've come up with a few things I think it might be:

1)Bad input shaft bearing. (how often do these fail?)
2)Bad throwout bearing (makes lots of noise while sitting in neutral)
3)Bad spring on clutch disk, possibly rattling around.

I plan on buying a clutch kit this weekend and starting there with new bearings. Best thing to do at the moment?

Is your clutch adjusted properly?

I had to re-adjust it this morning because on my way home from work last night I could hardly get it in gear. Seems to be working ok now...

Edit: according to the previous owner, the clutch was replaced a few months ago. I didn't ask what all he changed.
