[s-cars] 6-speed questions

[Charlie Smith]

Hi Paul -

I checked the FA on the DSY as used in the '99 S4.  The ratios are the
same as the UrS4/UrS6 6 speed gearboxes.  This is just a bit shorter
on 5th and 6th than the earlier S4tt (EDU) gearbox.

DSY ratios are:
---------------
1st    3.5
2nd    1.89
3rd    1.32
4th    1.03
5th    0.86
6th    0.73

EDU ratios (earlier S4tt)
-------------------------
1st    3.5
2nd    1.89
3rd    1.32
4th    1.03
5th    0.81
6th    0.68

CRB ratios (RS2)
----------------
1st    3.5
2nd    1.89
3rd    1.32
4th    1.03
5th    0.86
6th    0.71
