So if you're doing the filter change, you should have 12 liters on hand?

KRAM36, changed my 02 when i bought it at 46k 6 years ago, if i remember correctly about 6L was enough with pan drop and filter change. Last year i bought a 20L Pentosin from amazon for about $220. the car was at 86k. For three weeks in a row i drained and refilled (drain without pan drop and filter change was only about 4L), on the fourth week i drained, dropped the pan and changed the filter, this was the only method i could figure for a "flush". turned out just right with the 20L jug. What a noticeable difference in transmission performance. just my experience, hope it gives you some direction.

Never drive in any mode but M. Keep revs between 3-4k at steady driving. When in a 55 zone the car does not need to be in 5th, fourth runs at 3100 or so. You can learn to down shift "safely" breaking with left foot and throttle blipping with right to rev match. Ya, the 02 isn't new enough for the computer to do that. Completely different than the wife's 2014 Q50, the computer does the rev match for you as all new cars do. Tip in manual mode is a great experience, don't miss driving a stick.

Off the comments in that article I was figuring to have 7 liters on hand, but in the article itself he says to have a container that can hold 12 liters for draining. I'm not looking to do a complete flush like you did. Trans shifts fine, just figure it's time to do the filter change.

Yeah, that wheel looks great, but the price doesn't.

How would you get the filter changed unless you drain the sump?

I do plan to drain the fluid and pull the sump. Most of the comments said said 6.5 liters was all they could get back in.

How much fluid do you think I need on hand?

I'm wondering why you don't drain the whole trans as long as you've drained the sump and replace all the fluid as per Dempsey.

Were does it say in that DIY link about replacing all the fluid? I'm not seeing it.
