Can't answer for 230 engine, but the amounts on 320 wary. When some members report pulling 3.5 quarts in the procedure above, I got less than 3 quarts.
Shops usually charge for 4 or 5 quarts.
It is good idea to confirm the level with a dipstick after the job.
Also beware of potential saturation process in the transmission. After I flushed mine it took me almost 100 miles of driving before level stabilized.
