One of VW's finer engineering feats......  sure go ahead and mix
the two.  Now if you're a real glutton for punishment what you
could do is jack the Van up and drain the old oil.  Then refill with
Automatic trans fluid and start the Van.   With the engine idling
slip the trans into 3rd and slowly let out the clutch.  The usual
warnings about vehicles with running engines and transaxles
engaged apply here.  Be careful and pay attention!  With the
ATF sloshing around it will clean out the insides probably as
best possible w/o splitting the case halves.  Drain the ATF after
10 minutes or so and then refill with your favorite brand of GL4
synthetic gear oil.   The ATF is highly detergent and any dirt
or other trans junk will remain suspended and will mix with
the GL4.  If you're really paranoid about stuff floating about the
transaxle's innards then, like shampoo, do the ATF splooge
thing again.  After 20-30 minutes of sloshing around the insides
of your gearbox will be as clean as you can get.  Then dump
the ATF and refill with the GL4.   Since the trans is not under
load but just 'spinning' the lightweight 10W ATF will provide
enough lubrication properties to keep things from wearing while
it cleans the internal surfaces.   As usual- YMMV!  At least
this has worked for me when dealing with gearboxes that
have sat for the last 10 years and the old oil is like tar!

PS- I've heard of people using Diesel instead of ATF.  Personally,
I can't stand the smell of Diesel so I go for the cheapest ATF I
can find!  You ever get a whiff of 30 year old gear oil??  Yuck!
