I bought mine at Sears for not that much (it is called "VW transmission plug
tool" and comes in its own little plastic pouch and everything).
However this tool worked great on my Jetta, it stank on my '85 manual tranny
Vanagon (because that darn exhaust pipe was in the way of the drain plug).  I
used an old Jetta/Rabbit lug bolt and a pipe wrench as my "special tool".
The head of the lug bolt is the right size and this allows you to get in
there and get the plug out.

Hope this helps, now back to building the pyramids with only a come-along and
some logs :)
