Where was all this black oil coming from?

I always suspected it was oozing past the lower counter shaft where it comes through the case, but I sealed it up pretty good with Permatex when I installed the transmission. It doesn't look like it's coming out of the main shaft seal, because that part was relatively dry. It sure looks like it's coming out of the throw out bearing or seeping past the main input collar. front bearing retainer.

The weird thing is the transmission is filled with a nearly clear Redline Manual trans lube. It was the smoothest shifting, quietest running gear lube I found, and I tried a lot of them.

This black oily goo is all over the inside of my scatter shield, oozes out the throw-out fork boot and even though there are traces of it on the clutch itself, it never slipped and doesn't seem to be saturated like one would expect.

Any Ideas?
