318 poly wide block

So could I just clean everything? But if I have to take the transmission apart anyway I should just go ahead and replace the clutch too right? I mean at least then there would be a new clutch in it that I wouldn't have to worry about for hopefully quite some time, given it is driven properly.

If you do get to the point you have to take it apart, and you might be "there" now, I would certainly replace the clutch unless it looks good and you find "something else" that is for sure the problem

I'm starting to think more and more it is "junk" in the clutch. Is there a bottom cover on the bellhousing?
