[Vwdiesel] Trans oil

[dennis pantazis]

i am chaging my grear lube as well. i am reading the bentley manual and the
only thing it referes to is checking and topping off the lube for manual
trans. i see a drain plug on the final drive/diff as well, but no fill hole.
they cover the final drive in the automatic section.

do the manual tranny and diff share the same lube?  i would think so, but i
want to make sure.

aside from draining, is there anything special i need to do if i switch from
unknown, presumably dino lube to synthetic gear lube?
