I did the first one around 90k,(it went into limp mode) the second 120k and now 133k,
I've always used Audi fluid with no additives.

I finished the fluid/filter change last night and took it for a test drive. The tranny shifts as smooth as ever, with no problems. It even shifts smoother now than when I bought the car 4 1/2 years ago with half the miles. I highly recommend changing the fluid and filter every 30k. This <a href="http://www.audipages.com/Tech_Articles/auto_transmission/autotranservicing.html">procedure</a>, (Thanks Paul) replaces about 6.5-7 quarts of the 8.3 quart total fill.

Even if the fluid is really thick and black the first time you change it, "I" do not recommend doing a second fluid flush/change right away. Wait until next oil change. You do not want the fluid to get to "clean", (a new ATF fluid does a to "good" job loosing particles than the old one did) it might loosen bigger sediments inside the tranny, and clog something. I believe that one fluid/filter change every 20-30k will greatly prolong the life of your tranny. If this does not help your tranny, try adding some of <a href="https://forums.audiworld.com/a8/msgs/109657.phtml">this</a> before going to a different fluid.

Disclaimer: I'm no mechanic, I only hope this info helps someone with tranny issues.

 

And why not add the Lube Guard to the new fluid?

 

The fluid was green/yellowish coming out, but black once in the bucket. The magnets each had sediments on them, About 1-2 mm thick on each magnet, not shavings like a chia pet, but more like thick gravy,(normal wear). I could have waited another 13k but I figured I rather do it now, (winter) than in the summer. I see no reason to add Lube Guard as long as a normal fluid/filter change does the job. Plan "B" would be to add Lubegard like I said earlier, before trying a different fluid altogether.

I do not think using Lubegard is wrong, but I see no reason for me to put it in, since I have had no problems with my tranny's.

 

All of my questions I know are really dumb, but I really am learning a lot of stuff from you guys.

Yes, this procedure covers the A8 from 97-2003, US model, some part #'s may differ

 

Post facelift has a different filter.

 

Dealer is asking $450 for tranny fluid change.

 

I've changed the fluid. Thanks to Paul's writeup it wasn't that hard. The trick is getting the car level. I used a set of rhino ramps,2 jack stands and a 4ft level.
