Looking for transmission multiswitch 94 100Q

[Jason]

It looks like the multiswitch for the auto tranny in my car (94 100Q
Wagon) has gone flaky.  It switches from D to 3 randomly and if you
put it in N it go to R.  Anyone have one sitting around in a tranny?
The only yard around here with one won't allow me to remove it from
the tranny.  I believe one from early A8 or A6 will fit as well (as
long as they are 4 speed).
