You don't get all the fluid out, you get like 60% of it replaced with this method. Then you can do another flush and fill later down the line. It's a much more gentle method as opposed to forcing fluid through the lines under pressure.

I've done this on my 2000 540i Touring at 177k miles, it's now at 184k miles and shifts great. I've also done it on a 1995 750il at 187k miles, it's now at 200k miles with the next owner and drives great. Most recently I did it to a Range Rover at 160k miles, and the current owner is very satisfied with it.
