hi.
sure, you can 'drive' a vanagon transaxle with an electric motor say, to
test if it functions,
but without any real load on it .............it's not a real test.
You'd have to run one on a dyno, so it could be under load, ....and come
to think of it, under both acceleration and deceleration.
I could be noisy under load, and quite otherwise, for example.
You can also do a basic 'function test' just turning the input shaft by
hand, operating the shift lever etc. For that you sort of need 3 hands, one
for each output flange, and one for the input shaft.
but the only 'real' test is to either install and drive it, or tear it all
down and inspect/rebuild.
A vanagon 2WD trans is actually quite easy to R & R - you just leave the
engine supported in place, remove the trans. Only a few connections
actually.
As long as you don't run into stuck/rusted/stripped fasteners and such, it's
not a bad job at all, like under two hours out, and two hours back in.
I always get distracted on related small things that need attention myself
though , lol.
I'd say check that spare trans - that each gear works, then put it your van
and see how it is. Or rig up your electric motor test rig. And if it passes
that test, then put it in.
have fun in any case,
stay cozy !
Scott

For sure. Yes! :)
I looked at the pics of the 091 transmission in my Bentley. w/o one
apart, up close and personal, it's hard to see how it all works. But I
get the gist of how certain shafts (or even the case?) could be
affected if something was left unrepaired too long.

Thanks Scott.
I actually have a spare from a 1980/81 air cooled. Didn't test drive it
though.
IIRC, a Vanagon transmission input shaft sticks out ~ 1". I wonder if
I could hook up an electric motor via belt/pulley to bench test the
spare transmission for any obvious defects? (noises, inop gears).
Likely someone has thought of trying this already though.
