Gear Hello Guys, I’m new to this forum. I recently bought a 01 TA WS6 with 39k on it, it is a completely stock A4. I want to put a better performing gear in it but don’t know which one would be best. I appreciate all the advice!

What gears does it have now ?
I would also consider a different torque converter.
If 3.23's I would leave the gears and go with a yank Pt4000.
If 2.73's I would go with 3.73's and a yank Pt4000.

I have no clue what gear it has now and I can’t check because it’s wrapped up for the winter. My first TA and I don’t know sh*t about them. I’m still looking on google right now to figure out if they come standard with a 9 bolt rear.

From the factory, a 2001 TA WS6 A4 would have come with the GM 7.625" 10 bolt containing 3.23 gears ( option code GU5 ) and Torsen 'posi/carrier'.
Typically A4 cars are changed to 3.73s' and an aftermarket torque convertor for performance. Both mods are great when both done. Individually 3.73s' are good but not as good as a good stall in the range of 3500-4000 such as a Yank SS3600 or CircleD equivalent.
The little 10 bolt holds up well with an A4.

As @FirstYrLS1Z posted above, your car came stock with a 3.23 and Torsen LSD. There was no other option for a 2001 WS6 automatic car (3.23 was a mandatory option for a WS6 A4).
I wouldn't change the gears at all, if it were mine. IMO, 3.23 is a good all-around street ratio with a 4L60E transmission. A torque converter upgrade would be my choice instead - some good ones have already been recommended above - MUCH bigger bang for the buck than a 3.23-3.73 swap in this application.

^^^ 3.23s' are a good/great gear. For the Camaro Z28s' A4 and Firebird TAs' A4,the 3.23 was the optional 'performance axle package'. Police B4Cs' automatically got the 3.23s' as part of the package. I like/liked my 3.23s' with the Yank SS3600,but I'm 'old school' and extreme and run 4.56s' for the wicked 1st and 2nd gear of 'light to light' streetfighting.
