I also found a plastic piece in the pan as well (see last photo.) No idea what it does.
Yea, why not?
As for the "mystery part", read the stickies at the top of this section of the forum

A machine pushes oil backwards through the system and and roll seals. I recommend dropping the pan and changing filter every 15,000, or atleast once a year

Many transmission shops that I've visited dont use that style as the non passive type is quicker (from my understanding). Thus quicker = more can be done in a day = more money.
