That's not the issue. The rear differential has to match the front,
which is internal to the tranny- and the rear differential is set up
for a 4.11 final drive transmission. You'd end up with a substantial
front/rear speed difference and you'd destroy the center differential
in short order (not to mention, you'd never be able to lock the
center differential, which you can do in the older transmissions- the
car wouldn't even start moving).
In order to go to an older 10v transmission, you'd also have to swap
out the rear differential, which may or may not be possible. You'd
also loose the seatbelt pretensioning system unless you bought a
tranny from an 1989-1990 model; any 5000's would be out since they
don't have it, and with the airbag, it's an important system to have
functioning.
I don't even know if the older transmissions would fit, given the 3B
clutch and flywheel are unique to the engine (larger and lighter,
respectively, than the 10vt).
Supposedly the biturbo S4 transmission will come very close to
fitting, but nobody's ever sat down to really figure out if it will
work. Charlie Smith is the best person to talk to about the
C-platform transmissions. Search the archives for his name, along
with "transmission" and you'll probably hit a lot of posts on these
subjects.
