I know little about transmissions so I'm asking for information from
those who've learned already...

   How does the locker system work on a Vanagon transmission?   How do
limited slip differentials work?   Can I have either one of these systems
installed into my Vanagon 5sp manual transmission when I get it rebuilt?
I know the Vanagon 5sp manual trans is fairly rare, so I doubt there is an
"app" for a Limited slip differential or a locker already available, but
I'm interested in having my current tranny modified, somehow,  to produce
more  low traction drive..

  I am already planning on refurbishing my transmission when I return this
spring from an extended winter trip to the Desert.   I have owned and
driven vehicles in the past with limited slip differentials and they are
excellent,    If  cost is not too great, that would probably be the most
convenient for my needs...A locking differential/rear end, that would also
work just fine....I don't often find myself  where I'm needing just a
little bit more traction...I usually just get stopped by the actions of
other vehicles and can't get moving again........If I had to, I could
easily get out and go under the van, even, to lock the differential and go
again....then release that when the hill or the sand wash was in my
mirrors...I don't mind doing the locking hubs on my 4x4 pick up 4wd
system...A limited slip might let me avoid getting stuck in the first
place...but cost is also a factor and I see many of the traction rear ends
are quite expensive before you even start the machine work to install
them...

  Does anyone have any knowledge to share on what might be possible?    I
know having my current 5sp transmission rebuilt will probably be pretty
expensive, but the 5sp is a very good transmission when combined with my
2.0 liter ABA hybrid inline motor.  When I have this gearbox totally apart
I'd really be keen on modifying it to somehow give me better drive, if it
isn't going to cost me an arm and a leg.   Ideas?
