Some flush has a metal 'ball' with a diaphragm in the middle, some are a long tube with a free-floating piston in the middle. There may be others.
Most are setup so you put NEW atf in the top. then you have 2 lines,
open trans cooler line, now you have 2
new line to cooler
old line 'from' trans
start. run/rev till full.
disconnect/reconnect
now you have 'tube' filled with old fluid! and a clean car!!
Warning:
Expect MIL for cars that compare TO & FROM pressure, like Honda
Use ~12qt on ~3qt D&F, 9qt total to make up for lost fluid
When your manual says do a D&F every 15kMi, can you do the whole thing at 45k? Or 60k?
I don't f'kin know. I do D&F at ~10k, so this balances out. Takes less time than a LOF.
Get ATF and drain plug sealing washer (!!!!!) at Honda.
