Solve the puzzle? Draining converter with Magnum flex plate

Following up....since I had the pan off and the fluid was so cooked, I decided to pull the valve body and do a better inspection. Turns out the front band is toast. No material left on it. Rear band doesn't look much better. Not sure why both were so far out of adjustment. Gotta come out. I found an A999 "in good condition" to swap in to get me by until this winter when I can get my 42RH built and installed. Fingers crossed on the A999. Anyway....I found a pretty good video on a full system flush. Won't do me any good but maybe for someone else down the road. It's pretty much what George Jets described. Cheers.
