I had initially ordered 5L but decided to get one extra just in case - glad I did! For the fill process, I just followed the general guidelines mentioned earlier. Filled up about 4L before it started leaking out of the fill hole, hand screwed the fill plug back in (not tight) started the car, put it in Park, maintained 2000rpm for about 70-80 seconds or so, got back under the car, took the fill screw out and sure enough I was able to put another 1.7L or so in before it started leaking out again. Tightened up the fill screw, took it for a mellow test drive and rowed through the gears several times, everything seems fine.
The new fluid definitely appeared cleaner than the old fluid that came out. The old side filter material felt like it was worn out, felt like the material was falling apart.
