URS4 transmission problem.

[Bob Rossato]

1st gear is toast.  Common failure on the earlier transmissions.  Tell your
friend that this is his opportunity to upgrade to a close ratio 6-spd.  If
he gets a CRB (RS2 6spd gearbox) or a late CGR (S2 6sd gearbox) they have a
hardened main shaft and wider 1st gear.  Though they're getting tougher to
find.  It's not a direct swapout as you do have to change the tail housings
between the transmissions in order to fit in the C4 chassis, as well as a
small cover where the reverse switch is mounted, but it's no big deal.  Many
have gone that route, myself included.  Conversely he could try to locate a
CBL (S4/6 6spd) which will be a direct swap but won't have the hardened main
shaft, though I believe the later ones have a wider 1st gear.  They would be
cheaper than a CRB/CGR.  These are all imported from Germany, or some Audi
tuners may have them, and are all used of course.  Have him join the S-car
list and get more info.
