The tc is in the bowls of the tranny and it's full of oil, correct? The drain plug is at the bottom of the pan.
The tranny holds 9 quarts (I think) and the Bently states you can drain 4 qts, the rest stays in the bowls of the TC. In actuality, it's about a six quart change out when you drop the pan.

I am already on top of that one. My mechanic suggested yesterday that he wants all of the other stuff out of there and it may take a little more doing. He wants me to drive approximately 1000 more miles and then have the fluid only flushed once again to be absolutely certain.

When I spoke with Swepco for instance I spoke with the head Technical Project manager. He claimed it was fine for ZF transmissions. I asked what proof does he have, and he said he had a letters from both ZF Germany and from ZF headquarters in the US stating it was cleared by ZF to use the Fluid. I asked him if he'd be so kind to fax me a copy which he did. Yes, there are such a letters but when I read deeply into the letter that approval was specifically for the ZF transmission used on a bus for the Phoenix transportation district. I'm sure the fluid is okay for that transmission but what about the very specific one we have on our A8's?
I know for a fact that there are serious differences between the A8 ZF transmission and the other ZF transmissions there are on the market. Mainly because of the Quattro system. I can't even tell you how many ZF Transmission rebuilding shops I spoke with that said sure I work on rebuilding ZF transmissions. I said I have an Audi A8 and then their tune changed. Sorry, that's one I won't get near. Because of the Quattro system it has completely unique qualities and they won't get near it. The one that is most local to where I live was Peter Schmidt transmissions in Burlingame California. He knows ZF transmissions backwards and forwards for Benz, BMW etc. I couldn't convince him for the life of me to even look at mine when I mentioned I had an Audi A8 Quattro.
Interestingly enough, Even Peter Schmidt's shop agreed with the others. There's simply no such thing as life time fluid, change it out @ 50K intervals with the filter and only, use the Audi recommended Transmission fluid. If it is as unique as everyone claims it is, and I know from years of experience of owning this car that many parts on this car fall into that category, then we are dealing with a very different beast here and it's requirements are very specific.

It would be interesting to know which transmission version is installed in your car.
Build Date: Version
7/96-11/96 DPZ
11/96-2/97 DSM
3/97-1998 DTE
The build date is on a plate in the drivers door frame and the transmission version is on the transmission and should be on a tag in the trunk (the latter missing in my car). This info would be helpful in cataloging problems to version.

The torque converter is a turbine that's fluid coupled to another turbine, with both enclosed in a bagel shaped housing.
The housing is bolted to the the flywheel and rotates at engine speed. Normally the housing doesn't even have a drain plug, so at best, you can only drain about half the ATF fluid from it. If it does have a drain plug, you can drain all the fluid only if you rotate the housing so the drain plug it on the bottom.<ul><li><a href="http://www.howstuffworks.com/torque-converter.htm">HowStuffWorks.com -- torque converters</a></li></ul>

I mention some letters I was faxed from the Swepco Technical Project Manager further down this thread titled:
More Info Related To My Research When Talking With Fluid Manufacturers - Dommi3 2002-11-22
Both of those letters came from that Vernon HIlls office, one being a forward from ZF Germany.
It may be a good idea to contact them next if we have any further concerns. I've pretty much made up my mind at this point based on the data I was able to gather in the time frame I needed to.
