Want to drain and fill both front differential and center differential (transfer case).
Saw there were some posts already on 6speed about this, but they're confusing. People appear to be going back and forth in those threads and talking about the transmission / differential interchangeably.
Figured I'd start a thread to make it clear for others.

I did locate the front differential and its FILL plug.
I did locate the transfer case (center diff) and its separate fill plug too.
I did not locate drain plugs for either differential.
Best I could do was to top off front and center diffs.

Anyone have any info on what needs to be done to drop either diff to be able to access drain plugs if there are any.
Or, what needs to be done to swap the fluid via the tubing method (disconnect both diff's tubes), which a PDF does exist for but raises more questions than answers for me.
Mechanic couldn't figure it out either, specializes in VW, Audi, Bentley. Really don't want to take it to the dealer for this if I don't have to.
Also, if you had someone do it for you, how many labor hours was it, so we're not getting gouged?

Thanks!
