My daughter and I rebuilt the AT from our 84 about 5 years ago. It had been
"rebuilt" poorly shortly before I got it after the same type of seal problem
that you are contemplating. It shifted very erratically for the first couple
of years I had it and finally started to slip. I believe that the previous
rebuilder failed to clean the gunk out of the valve body completely. It is
sort of a hydraulic ECU that controls the shifting, very interesting to work
on.
Anyway, I could be wrong, but I don't think that the Rabbit AT can be
substituted as a whole; the output end is rather different. I think many of
the internal parts may be the same, but you would need to check with a Pro. I
found most of the useful info about the rebuilding in a Rabbit Bentley manual
since the Vanagon book had very little. The job can be done without special
tools, if you find the right manuals and are patient and determined.
I have not gone into the final drive (differential). Perhaps someone else
can advise you about the seals. I suspect that my current van (91 GL) has a
similar seal weakness, so I try to change the AT fluid and the final drive oil
regularly.
BTW I got a rebuilt AT for a Saab 900 in Chicago about a year ago for
$995.
I think the name of the place is Classic Imports; they have a website.
Good luck,
