There is a VERY advanced method of flushing the Germans use but I don't know if it's state side. They actually run the car on a dyno and have a machine that injects and extracts the fluid as the vehicle is moving under load. It's very wild stuff and works extremely well, it's supposed to prevent all the horrors that come with a normal power flush machine.

Personally if you have under 80k, drain an fill 3-4 times then repeat one cycle every 10k and your fine. I've learned from my Xc70 (Aw55) how to properly prevent this awful thing from happening. The trans was definitely slapping gears at 65k, once I did a full 12 quart drain an fill it worked it's way out completely by 70k. I have had zero issue's since then, I did another drain an fill at 85k (A simple 3 quart replace) and the fluid was almost perfect. Again now at almost 100k, I'm going to do it again and keep repeating the process. 20$ and 1 hour of my time + a small mess is worth it to stop a MASSIVE failure.

I have the never had valve body replaced... ;)

EDIT! The Tim Eckhart Method.

I FOUND IT! ON AN S60 LOL!

Here are the original video's!

I think it's just the english version.
 
My serial, just for reference.

I guess I'm SOL, these drain and fills do work. I've done them since 60k when I bought the car, changing every 25k. I have got very minimal symptoms which go away with each flush.
 
Awesome! Thankyou!
