Need some advice. Got the dreaded 17125 error code (Torque Converter Clutch Circ Performance or Stuck Off) right after a strange clunk was heard while shifting hard going up a very steep hill.

Everything seems to be back to normal now, and so I'm wondering two things:

a) Does one occurence of the 17125 just once (accompanied with a clunk) indicate that the converter is toast, or could it be just a momentary problem with transmission fluid (at least at 15% grade hill, very steep)?

b) If the converter is bad, do I need to replace it right now or can it handle a gentle 600 mile drive home to the greatest audi shop I no (Wolfsport in Berkeley)? (The car is on a road trip with my girl in WA with no independent dealers around, only a crap rated (on 1.8t.org) audi dealer.

Any help you can provide would be great. I'm really trying to avoid plunking down more money on this thing right now, but don't want to pay 5K for a new tranny.

world can one make a Tip "Shift hard". It shifts the same no matter what you do.

Please tell me it wasn't "rev' dropped"

As for going 600 miles on it, If it's constantly slipping I'd say bad idea, but if it's ok under 40% load or so and not slipping, drive it....

Should have said "while shifting sloppily and softly, but trying to make the tip feel like a real tranny"

(I'm telling you if giving up a manual for the girl isn't a sacrifice then I don't know what is.)

anything other than chooses a gear and that's that.
Anyway, is the converter slipping still? When, how much, all gears?

1) The transmission isn't slipping (yet), I head a clunk, the car shifted, and then the check engine light came on.

2) Re: sloppily my point was just that all automatics shift sloppily

3)definitely not rev dropped

4) real tranny= manual, not the other thing, you with the dirty mind

thanks for the help, sorry about the lack of clarity earlier.

throw the 17125 code. It is pretty common to find that code randomly. You need to worry when it is always there. (meaning everytime you drive the car the code comes back).

About every 3-4 months I get a random and hard "Clunk" from my TIP also. Have no idea what causes it. Sometimes it will toss the trans into limp mode too. Clear the limp mode and the car works fine. Still trying to figure that one out.

When the seal in the TC finally fails and you have the 17125 code all the time it is still not a real serious issue. All this does is bring the TC to full 100% lock up at highway cruising speeds. It is really only a fuel economy thing. Autos were made for nearly 40 years without "lock up clutchs" in the TC.

If you watch a perfectly working TC you will see that it really only locks after 2000rpm when cruising. As soon as you put your foot down it unlocks the converter.

We put a few thousand miles on mine while trying to figure all this out.

thanks for the advice guys. Going to be patient, and see whether the code comes back. If it comes back, I guess the big brake kit will have to wait.
