My dealer did my 960 last month. They dropped the pan changed the filter, cleaned the pan and re-installed. They added 3 or 4 quarts of ATF they had laying around to bring the oil level up to operational and filled the machine up with 12 quarts of Redline D4ATF I brought with me. They then flushed the transmission replacing the old 66K mile fluid with the new synthetic. The machine works the same way the process in the FAQ runs. All it was is a rubber bladder that holds the new fluid and two hose connections to the radiator. The used fluid collected in a tank under the bladder. They fired up the car with wheels off the ground and ran the car in gear. The transmission did all the work doing the pumping. It took probably close to 15 to 20 minutes to exchange the fluid out.
