Operating Fluids question

Hey guys, planning a complete Fluid change on my 2017 GLS63 AMG.
I'm looking for the operating fluids datasheet https://operatingfluids.mercedes-benz.com but I found it really confusing.
Can any of you point me on the right direction for the MB-Approval for the following items?

-Transmission
-Transfer case
-Rear Differential
-Front Differential

Or what do you use?

Thanks in advance

David

Thanks for the answers guys.

I will go and check the owners manual. My thought was, what is written on the user's manual could be outdated, reason why I went to https://operatingfluids.mercedes-benz.com

Can you tell what fluids you use?

Owners manual has no information related to differentials and transfer case fluids.

Sorry for the late reply. I just noticed your post, if the specifications are not available in the manual, you should get a copy of WIS to help you out. I believe that the transfer case shares the 722.905 transmission fluid, so when you do transmission, both gets drained. I would appreciate someone confirming for me just in case, and correct me if I am wrong as I don't want you to mess things up.
