Dang!

I normally catch that....

Maybe they should lock posts over certain age! (Say a year of no replies.)

 

Still good info on the trans in this thread.

I come off my fair share of trans issues in my A4 B5 2.8. The trans did not do anything (ZF 5HP19, DRN). I had my trans shop take it apart: while all gears/shafts etc. were tip top, the clutch packs (there are several in there) were all worn down.
What likely killed it was a leak in the trans cooler lines running through the radiator; coolant/water got in.

The used parts trans I bought (CJP, the correct one for my year/model) and installed pulled strong in first and 2nd, but nothing in 3rd, and after 5 min nothing in no gear. The 3rd trans (CJP) did not display in the gear selector, error code 'multi-position indicator'. After changing that one, everything worked (after 3 trans changes!).

The 2nd reason for me to read the thread was my constant struggle between the convenience, availability of an auto vs. the 'hold your gears no matter what torque demand' and assumed higher torque handling (upgraded clutch for power increased engine via turbo upgrades).

So any measure to improve the power capabilities of an automatic is of interest to me; as well as ways to teach an automatic (tiptronic style) to NOT shift every time I move the pedal (my idea would be a tiptronic that holds gears no matter what with only low and high rev override).

Out tune for the 3.0 Cougar swap allowed increase in line pressure which firmed up the shift; I was told VAGcom/Audi can't do it by software.

Ultimately, a 'stage 3' dual clutch auto (with fully manual option) would be the ideal solution for my needs!

 

Every A6 2.7T with the defective ZF torque converter (pretty much every single one) will eventually need a new torque converter. The rubber seal in the torque converter is defective and the torque converter does not lock up. So, basically the transmission is constantly slipping because the torque converter will not lock up. I replaced my torque converter on my A6 yesterday. It took 3 of us 18 hours with all the proper tools and a lift so no wonder Audi wants $3,000 in labor to change it. In order to change the torque converter in that car you have to remove all the front suspension, entire exhaust system, driveshaft, axles, and even the subframe and everything that comes with it. ZF is offering a discounted torque converter, but Audi's is still $750.

 

yeah mine is out, got quoted $1300, twelve hours labor and a 100 bucks for the part. Crazy expensive.

 

X2 on this one.
