The transfer case oil is integrated on the 722.9. Holds about 24 ounces at all times. You can drain and refill with 24 ounces, but it may not be worth the trouble. Technically the rear support has to be lowered.

Yes, I have had every fluid in all of my cars changed (in the past year). While I can not provide instructions, I am 100% positive the TC and trans were at the same time (connected in some way????) And the rear end was its own thing.

Yes. Many MBs with the 7G shares fluid with the transfer case I don't think all of them does but a lot. 9G on the other hand is seperate.
