Subject: Re: How do you drain "all" the fluid out of the tranny?
Content-Type: text/plain; charset=us-ascii
I do not have a good answer for this....hopefully someone else does.
The most common method from what I've gathered is....drain the old
oil....fill with new....drive around....drain again and fill again with
new oil. This way, the 1.3 qts. remaining is at least newer than the
old, but still mixed with some old oil. But this way you also end up
spending another $30-40 if you use the best oil, as you should since
these transmissions are so fragile and so expensive. Rebuilds are
expensive too, though....very much so.
I suppose you could drive up onto a ramp of some sort to raise the area
where the 1.5 qts. hides....but I do not know if this is feasible and
have never heard of anyone doing it. I do not know whether you can suck
the old oil out with a vacum pump...don't see why not with the right
hose....hate to get it stuck in there!
I think most people just leave the old oil in. I did. It's ok to mix
redline with the old oil....even if the old is not synthetic. Says so
right on the can. VW considers the trans. oil to be "lifetime," never
to be changed during the life of the vehicle. I was surprised at how
clean and fresh looking my old transaxle looked after 90,000
miles...still translucent...not at all black.
Good Luck
