Trans flush with no convertor plug…

Whats procedure? I'm thinking pull cooler line into bucket and run another line back to trans and gravity feed it new fluid in via funnel at about the same rate? In neutral so it pumps? Flush until it runs red or out of fresh ATF? Cycle the selector a few times to clear the passages? Dumb they didn't put a plug on this convertor. Fluid came out looking like oil but didn't smell burned at all. Weird. 194k miles FWD Transaxle. Thanks!
