Ive been searching and have found a few different answers.

I'm helping a friend of mien service his 07 RL Tech.

Were going to be replacing all fluids front to back, can come one please confirm this is correct:

Transmission Fluid Honda ATF DW-1 3 quarts
Front Diff (attached to transmission no addition service required)
Xfer Case (80w-90 hypoid gear fluid) 1 quart
Rear Diff DW-1 Fluid 2 quarts

Can anyone confirm this beforeI goto the dealer?

Transmission might require 3.5 qts.
As for the rear diff, DW1 is not compatible, even though the older Z1 is. Acura made a compatible fluid called DPSF that is made for this purpose.

Is dpsf the same this as shawd fluid?

From the linked thread, I believe that's what it's called. https://acurazine.com/forums/4g-tl-2009-2014-123/sh-awd-diff-fluid-816522/
The dealer can confirm what fluids you need also.

The DPSF cost around $12 for me. Oh yea, for the transfer case, I used Mobil 1 Synthetic 75W-90. Works great for me.

Don't forget to pick up two of these fluid pumps that screws onto the bottle to refill the transfer case and rear diff.
