I know there's a torque converter somewhere that hold more fuild but that's besides the point.
Having to drain/fill 3 times seems like a lot of waste as you are draining of the new oil on the 2nd and 3rd drain/fill.
I've searched high and low for this answer and my thinking is that it could only be the following.
1. Keeping costs lower
2. Subaru/Toyota thinks we are stupid and we might screw up the fluid change somehow.
3. Something might go wrong if the transmission fluid goes below the level of the overflow plug during the fluid change.
I was going to insert a thin tube through the refill plug or overflow hole and suck up as much of the old fluid as possible to get the most old stuff out. I'd thought I'd ask you guys before something goes wrong.

Do you happen to have a part # for the drain and refill plug gaskets?
