My understanding is that the 959 uses computer controlled clutch packs to 
determine the F-R torque split.  I have heard that the automatic tranny/
center diffs on the V8q also had this sort of an arrangement.  It seems 
to make sense, as the tranny already has a separate control module to 
do the shifting ... it could probably sense whether front or rear was 
getting better traction.  Can anyone confirm that the V8q's box had this
capability?  Given this, is anyone familiar enough with the tranny to 
know if the center "diff" on the car could be removed and retrofitted 
on a MT?
