    I got them from T-Kan?????  This is from the Audi Brochure for 85+  But I
dont know what the 84 is.  I would liek to know.
1st     3.60:1
2nd     2.13:1
3rd     1.46:1
4th     1.07:1
5th     0.83:1
Rev     3.50:1
Final   4.11:1

    As a side note, with exception to fifth, this is VERY close to VW GTI
tranny.  GTI has lower 4 and 5 gear ratios though.  Like   .92 5th or something.

    Yea, I ahve experience with this one. :-)  My car is louder but my 84' with
stiffer springs and all is MUCH more responsive than the 87'.  Of course I have
no AC and battery in trunk which helped A LOT.
