Dex VI is not recommended for use in the A4.

I thought GM recommended the Dexron VI as backfill for all its automatic transmissions.

AMSOIL has not said anything, but I suspect that they won't leave a void in their product lineup for long. I'll keep you posted.

I read the Amsoil Tech. Service Bulletin 98-2 on these flushes (I'll have to read it again) but in any event this will be something the dealership will have to perform. It says initial fill is 5 quarts of Tranny fluid. Then it says Total fill is 11.0 quarts so how much fluid am I going to need? 11 qts. x 10.00 is $110 for just the fluid and that's if the dealer lets you bring your own so if you use theirs it is going to cost alot more just for the fluid

"Never shut off the vehicle while the Trans fluid level plug is removed".
I think this sounds like a job for the dealership.

11mm isn't that the same size for the rear end diff. which is alot easier to do.

LS WON - FYI, the AMSOIL Preferred Customer Program price is about 20% under what you've listed, so not all that bad - but as mentioned above, don't currently have anything available for Dexron VI applications. But, for the 05s, AMSOIL is still listing that its ATF is suitable (as it is a Dexron III fluid).

For a flush, you'll need to get a full case (12 quarts). But, my recommendation, and what I have done with my auto trannies vehicles, is to drop the pan, clean it, replace the filter if it is old/dirty, put the pad back, then add the 5 quarts and verify level. This doesn't get the fluid out of the torque converter, so I use a "feed and bleed" type approach. Do that once, then in a few thousand miles, do it again. Not perfect, but I am not a fan of "flush" machines, and in general prefer not to take any of my cars to the dealership if I can help it.

I have a trusty dealership to perform the auto trans service and I recall being told the same thing as I requested that they flush the auto trans at 30,000. Their approach was just to drain and add fluid as they also said there will be fluid left as you cannot get all the fluid out. I don't recall if they do the same as above drop the pan, clean it, replace the filter if necessary. Perhaps there is a second visit involved. But this process you explained to me sounds like what they were telling me a year ago. I am suffering from memory fade

There is a bulletin that states the Dex 6 goes back to cover the Dex III from 2005 and I was told that is what they use now for the A-4..
