Thanks for all this info  - I've been  wanting to switch tranny fluid for
some time -

One question: when switching to say  . . . redline - do you simply drain
the old fluid and then fill with the new (redline)? Or is some sort of
flush necessary?

but, i used castrol syntec because my friend did a torture test on one of
his demolishion cars. he filled his tranny with a leading brand of
synthetic oil and then drained it and ran his derbee. then after the
rally if the tranny was still motional, he jacked up the back tires and
let it run until the tranny seized. he repeated this four times with
different oils. they were valvoline, redline, castrol, and casite.
valvoline seized before the derby ended (which really pi**ed him off),
redline ran for around 45 minutes after the derbee, casite ran for only 5
minutes (close call), and castrol ran for 2 1/2 hrs. he did this in hopes
of being on a commercial, and submitted his tapes of the whole deal to
castrol. they rejected his numerous tries saying the experiment had too
many uncontrolled variables. anyways, thats why i used castrol. it !
!
came out on top by quite a bit in this little test.

Sean, that's impressive that the Castrol was able to keep his tranny
from seizing the longest.  However, not many people run their tranny
dry.  Especially those who care about their Sciroccos!  At least not
without noticing a huge puddle of tranny fluid under their car first. 
So for those of us like you and me who keep their tranny full, and do
check it now and then, let me give you the reason I think Redline is
better (I'm not a dealer).  Redline has an additive package that meets
Porsche and VW transaxle requirements.  Castrol does not. Maybe AMSoil
does, I don't know. This additive, in contrast to the actual
slipperiness of the fluid, actually ADDS friction to engaging gears and
syncros therby extending their service life, and decreasing gear grind. 
So having the slipperiest gear lube won't help much when you have no
synchros left.  That's my best advice.
