Curious and probably a dumb question, but where does the "junk" come from that collects inside the converter?

Doesn't the transmission filter pick it up?

I've changed a fair amount of transmission filters and sometimes find a few metal specks, but very few. Powder residue is a little more common.

The converter doesn't produce much residue on it's own. There's only a few Torringtons in there, and maybe a few shims.
Most of what you find is the same as you find in the pan.
The pump picks up filtered fluid and sends it to the converter and lube circuit first.
Some of the clutch material still finds it's way into the converter after a while.
Once it's thrown up under the overlap of the welded seam, it's not coming out of there.
The best reason to cut one open is to inspect the sprag and bearings and stator clearance, which affects the stall.

In my case, for some reason the front drum made contact with the back of the pump and wore a groove in it. This made a very fine aluminum dust that got by the filter screen. I don’t know what micron the screens are, but I’m guessing 100-150, which is quite large. Usually they are good enough for normal wear and tear. A stock filter probably would have caught most of it. But they are quite restrictive and can cause other issues.
