I used the $2 oil sucker and jammed the suction hose way down in the
pump, got out as much as I could, then refilled with ATF. Did that
again a couple days later figuring that got most of the old out, mostly
new in. After the second time it looked pretty clean a couple days
later when I checked the level.

reservoir draining replaces only a small amount, the pipes and box would
still have old fluid contaminating the fresh fluid.
On MOST Mercedes, draining the reservoir and refilling it changes about
HALF the fluid. The total content of 123s PS system is 1.4 liters (0.6
liters on 124/201).
What model and year car do you have that doesn't do that?
YOU can of course loosen the low pressure line while pouring fresh fluid
into the reservoir (you DON'T want it to go dry). I prefer to simply
change what's in the reservoir every 10/20kmi. That results in about 90%
being changed every 30-60kmi. Or you can change what's in the reservoir
3 or 4 times in 3 or 4 days (so each batch of fresh is completely mixed
with what's in there) and that will replace about 90%.
