Hi! Fellas!
My 09 RL is about 100k miles.
I'm planning to change the drive train fluid.
These are the lists.
1. Transmission(2.66L) -> Valvoline MAXlife dex/merc - 9qt
2. Transfer Case(0.43L) -> AMSOIL 80w90 GL5 - 1qt
3. Rear Differential(3.33L) -> Valvoline Maxlife dex/merc - 4qt

I'm not sure that Valvoline can be used for rear differential.
I know the fact that ATF-Z1 was used for both transmission and rear differential.
However, after ATF DW-1 has been released, DW-1 cannot be used for the rear diff but only used for transmission.

Here is the question. Is it fine to use Valvoline Maxlife dex/merc ATF fluid to Transmission and rear diff?
I saw many people who use Valvoline maxlife to transmission, but as rear differential fluid? hard to see...

Thank you for your reply in advance!

Don't worry, this fluid is great for the rear SH-AWD diff.

Thkan you for your reply!
My brother gave the ATF-Z1, so I just replaced with it.
Next time, I will do it with ACURA DPSF!

Yup; Acura DPSF & not Honda DPSF - they're different colours.

TonyCD

Different prices, at least.

OK, so let's see if I have this correct:
Transmission: ATF DW-1 (purchased from Honda dealer) and Valvoline are acceptable
Rear Diff: Acura DPSF and Valvoline are acceptable.
Right?

Now, is Honda DPSF acceptable for Acura rear diff?

Honda Dpsf is same fluid as Acura without "A" in part number. Remember that now some Honda vehicles have same mild version of shawd. See this thread

OK not sure the question was answered:

Is MaxLife acceptable for use in the automatic transmission.....yes or no??

altair47

Yes. https://sharena21.springcm.com/Publi...3-ac162d889bd1

Yes, I DID answer your question in the link I attached to my previous reply that you obviously didn't read. I answered it specifically and with the full name of the product variety you should and should not buy. Perhaps you'd like to go back and read it. Or, perhaps not.

No need to get pissy!! I did read it twice and STILL don't see where it specifically addresses Valvoline Maxlife use in the AUTOMATIC TRANSMISSION. The entire thread addresses only the rear diff....just sayin'.

No need to reply. I got the answer from altir47 up there.....thanks to him/her for that!!
