Anyone done a tranny fluid change yet? I see them done for older models but haven't seen one done for the C6.

its not recommended, you might create more problems for yourself, just fyi.

my indy audi shop recommended it (I'm at 56k) but I have not done it so far.

Why did they recommend it? Did you report an issue or did they just recommend it unsolicited?

I hear a flush can cause problems. I'm talking about changing the fluid (not using special machinery to flush it out).

Can someone confirm that a flush and a simple fluid change are different?

I think the recommendation is to drop the pan and do a filter change with the logic being that there will be loose particles after an ATF change that get dislodged and may cause issues. A new filter should catch those.

I am planning to do it this summer on both our cars - they both have 'lifetime' AT fills. I just do not feel comfortable with this proposition because they never specify what "lifetime" means. Lifetime could very well mean "until the AT fails".

I too feel like it should be done. Especially after seeing how so many of the C5's had old tranny fluid that looked like metallic paint.

Just don't know if I should do it myself or not. My biggest concern would be the fill (you have to get the temp right for an accurate fill). Also bluaparts.com doesn't sell kits for the C6. I'm wondering why.

I guess I'll just do some more research before I decide whether or not to do it myself or take it to the dealer.

I got mine done twice already.

Once at 46k miles using the Blue ATF TSB
Second time at 49k miles when they changed the Torque converter.

I read that after 75k-80k miles you shouldn't bother changing it because the fluid has become slush and changing it could break your tranny.

We have the ZF (GM) tranny's in our car, or atleast in my A6 3.2. I looked up youtube videos on how to change it... seemed hard, but not that hard.

They just don't have faith in the so called "lifetime" fluid and have changed the transmission fluid on their own Audis. I have had no issues with the transmission though (*knock knock*).

I had mine changed at 35K miles and will do it again at 70K miles. The transmission manufacturer recommneds getting it changed every 45K miles, even though Audi claims it is lifetime fluid.
