It has a gertrag differential. If you're asking about gear ratio, 6spds have a 3.42. Autos come with a 2.73, unless you have the performance ratio, which is 3.15. It's indicated by G90 and G92 on the RPO list in the glovebox (or under the left rear cargo bin cover on 97-99s.)

If you have an A4, drive the car at 75 mph in 3rd gear. The RPMs divided by 1000 will equal the rear end ratio.

If you have a MN6, do the same but in 4 th gear.

Thanks to Mike Mercury for posting this earlier.
