Has anyone tried (or know if it is even possible) to use a siphon pump in the fill tube? I have seen on other forums where guys have used a siphon pump to get ATF out through the fill tube.

I am getting ready to do a drain and fill on my 722.6, and I wanted to see all the options I have for getting as much fluid out as possible.

On a related note, does anyone have a picture of the transcooler return line? I tried searching for it, but didn't have much luck.
