I too am curious as to what makes these auto boxes fail. ZF seemed to have done such a good job.
From Paul's post on audiworld it looks like the torque converter wasnt that bad, and Paul's explanation of auto box operation seems to indicate that torque converters arent really expected to fail?

I had my transmission oil changed 3 years ago (at 79,000miles) and its still ok. Does this mean its safe to change it again because nothing got dislodged last time
I have also bought a cheap DGV manual box from Germany 2 years ago, but I have been thinking hard and am mostly concluding that I prefer the auto.
I dont think I could shift as smoothly as the auto does during acceleration, and my other real worry is dropping gear when wishing to accelerate on a motorway, I would have to remember which gears I cant select at certain speeds (first
) and also I would need to know which revs to match it to.
I wish I could keep the auto box but I am almost resigned that its going to fail in the future.
For what its worth I found this advice from a German website:

Ne, is not correct in such a way. The 4-Gang had to be still waited (oil change all 60tkm), with the 5-Gang was according to service schedule the no more planned. In addition the transmission (also the 4-Gang) reacts sensitively to inaccurate air mass and temperature levels. Since these feelers supply unnoticed falsified values with the time, the oil pressure in the transmission is wrongly computed, what increases the wear additionally. The new Tiptronic is thus not more badly - probably however maintenance and above all the air mass measurer (by the way with many Audis slowly steps out).
Recommendation here in the forum:
- ATF changes regularly (best with ZF Dortmund)
- Air mass measurers (LMM) directly along-change (with AUDI in the exchange, approx. 90€)
- Temperature transmitters likewise exchange with each toothed belt change
Then also the 5-Gang holds for a very long time. Automats are built, only evenly not for the eternity quite not if to >400NM lie close.
