If you have had problems with your tranny and a dealer did warrenty work let me know what dealer did the work and what work was done

the ECU because the original ECU wasn't "communicating" properly with the new trans. No modding done to my car though and they are NOT a mod friendly retailer.

Mine was slipping between shifts. Revs would shoot up in between 1st and 2nd, 2nd and 3rd, etc...

I have noticed the same phenomena on my RS6, but I'm getting the sense that mine is a very mild slippage...say 500 rpms or so. How many rpms was yours slipping, and what did you say to the dealer/AoA to get them to repair/replace the faulty parts? What was replaced, exactly? Thanks, CW

that happens. If I had kept my foot at maybe 3/4ths throttle between shifts, it would spike up to redline, as the tech did when he test drove it.

As it was described to me, and I'm sure everyone has a theory, the clutch discs in the transmission can't handle the transition of power from gear to gear. The software mapping from Audi is such that it was developed to have a smooth shift. What that does is put greater amounts of stress on the clutch discs while in that "transition" period between gears. You never hear about chipped gears, stripped gears, etc... because that part of the transmission is strong. It's the soft programming of the shifts and the resulting stress on the clutch discs. This is why chipping will invariably lead to failure unless they also chip the transmission to produce quicker, tighter shifts. My tech mentioned that the typical american Audi buyer doesn't want a "hard" shifting car. Given the fact that this was a $90,000 car, I don't think we are drawing from the same client base as say a WRX STi or Evo buyer. Maybe we expect something smoother.

They told me Audi would not fix the "problem" until they saw enough transmission problems, but the problem with only 1200+/- cars is that you can't make a great enough impact with the sheer numbers alone. He also told me the Euro mapping software for the RS6 and the RS6+ was much tighter and they practically had a zero failure rate.

I mentioned there were a number of aftermarket tuners out there that could essentially perform the same function as the Euro RS6's and of course the response was, "you'll void your warranty".

There you have it. That's what I know, which isn't much.

And BTW, they read these forums so it doesn't make any sense to discuss in a public forum about how you might have chipped your car. (I'm not saying you did, just be careful!) The trans is not a cheap thing!

In my case, trannie issues were accompanied by sporadic subpar performance. Replaced ECM, problems disappeared -- then returned. Later replaced wiring harness -- problems now gone for good, I think, after 14K miles.

That's just my case; doesn't mean yours is the same. But in resolving it, which required many weeks and a pre-arranged dealer tech call to a factory tech in Germany, I was told that the main ECM, and I'm not speaking of the tranny ECU, affects an incredible number of functions -- including the tranny.

And the ECM can malfunction due an errant wiring harness. My harness was "shorting out" in some of its communication with the ECM.

Sounds like your fix works fine, and it certainly was thorough! How long ago was it, in miles?

But I gotta ask: Is AoA really as dumb as they seem here? They have a solution to an expensive problem, but aren't willing to share it?

By that I mean, if the tighter Euro shift settings are problem-free, why not offer that as an option at the time of replacing a US tranny?

Meantime, if you dare to find a program that will enable the tranny to work better, Audi says no cuz their name is not on it & they void related warranty claims. So you stay stock, the tranny goes, and AoA is out a bundle of money.

Isn't that dumb?

Maybe not, since they probably want to maintain uniformity among US cars. But that is their wish; if I was an owner needing a new tranny, I might wish otherwise.

When the car comes out of warranty, and assuming I still own it, I'll definitely get a transmission software upgrade from someone, but not until then.

When the tech drove it, he accelerated harder and the revs jumped to red line and "clunked" into the next gear. Very hard shift as a result of slippage. Just imagine accelerating under half throttle, slip the transmission into neutral while continuing to hold down 1/2 way on the pedal, then throw it back into drive. That's what it felt like.

As for the dealer and AoA, I told them nothing. It was self explanatory and they ordered a new trans instantly. Whole thing took about two weeks from start to finish.
