I did mine today, I figured a better way (i guess) to get most of the old fluid out and here it is:
1) jack up the front wheels, remove the under engine cover to access the connections of the supply and return tubes to the cooler .
2) remove the dip stick, get under the car and undo the drain plug, keep it draining, typically you should collect 4 to 5 liters.
3) disconnect both supply and return tubes and keep them draining, you should collect 1 to 1.5 liters more.
4) blow compressed air into both supply and return lines, you should see more oil coming out from the AT drain hole.
5) blow compressed air into the cooler using the supply side, you should get some oil coming from the return line.
6) leave the car as it is for 1/2 hour for maximum drainage.
7) if you measure what you have collected, it should be between 6 and 7 liters (my case was 6.5 liters).
8) prepare the same amount of fresh fluid, put the drainage plug back on and tighten it well. Reconnect supply and return lines.
9) fill up the transmission with the fresh fluid up to only 6 liters.
10) start the engine, shift gears several times.
11) stop the engine, check the fluid level, and add if necessary and check again till the fluid level is on mark. It is good to start with only 6 liters and add afterwards, rather than putting more and finding out later that you put too much, then you will have to get under the car and disconnect the return line and let it drain.
10) put the under engine cover back on, clean up the mess and you are done.
