Dexron 6 to Honda Z-1 #5283238 12/02/19 06:03 PM

I know this may be a strange question but here goes...

I have a 2008 Honda Civic with an automatic transmission in it. Honda calls for Z-1 transmission fluid.

Z-1 has been superceded by DW-1 fluid.

I was looking at Rock Auto's website and they show Dexron 6 as being compatible with my Civic.

I also saw where RA sells a friction modifier (ATP brand AT-203) which supposedly makes "any conventional" Dexron fluid, such as Dex 3, compatible with the Z-1 fluid.

The main reason I am asking all of this is because I also have a 2008 Suburban and I have about a case of Dex 6 left over from the transmission service I did on it.

So if the full synthetic Dex 6 will work as a replacement for the Z-1/DW-1 then I would much rather use it instead since it is synthetic.

If I chose to use it do you think the friction modifier would be necessary.

Any help would be appreciated.

My opinion is to only use the transmission fluid the maker recommends. I'm not a Honda guy but please check with the dealership to make sure the DW-1 is correct.


Save the Dex 6 for future drain and fills for the Suburban about 30K from the transmission service.

Is ATF z1 the same as ATF dw1?
Answer: aft-dw1 is the replacement for atf-z1. If your honda specifies atf-z1 you can use atf- dw1. Both fluids are compatible with each other.

I would go with the dw1 and forget about using the Dexron 6

Use something that claims DW1 or Z1, such as Maxlife or Castrol Full Synthetic ATF smile

I once accidentally changed the fluid in a Honda transmission with Dexron 6 and it ran just fine for the next 1,000 miles I had it. Ideally you use what the manufacturer specifies but on a 12 year old Civic you don't have much to lose and chances are you will be fine. The differences in fluid specs between manufacturers isn't all that huge, hence the multi-make fluids.

I was hoping I could find the specifications for the Dex 6 and the Z-1/DW-1 fluids so that I could compare them but I don't have a clue as to where to even begin looking.

That is why I posted here, because I was hoping someone could point me in the right direction with actual fluid specs and not just opinion.

Interesting find on the friction modifier.

There is something in Z-1/DW-1 that changes the shift feel. I tried Maxlife in an 09 Honda using Z-1 and was really not happy with the result.

Maybe give it a whirl without the friction modifier and see what happens. If it stinks, order the modifier and add it?

The only downside is that if you hate it - you have to cycle through a ton of fluid to replace it all.

Having been there, the money saved was not worth the squeeze in the end.

I am going through this now as I have a slightly older Civic than yours, built for DW-1. Z-1 is the low-viscosity fluid Honda issued paralled to GM' DexIII/DexVI change and Toyota's T-IV/WS changeover.

A lot of research here and on Honda forums show most people happily substitute MaxLife for DW-1 (or Z-1) with long years of success. However, MaxLife is also a low-viscosity fluid like the newer generation (DexVI, etc). Personally, based on a lot of forum research but no personal experience yet, I am gong to use MaxLife instead of Z-1, and some Lubegard Red for seal conditioning and heat management (it does both).

I would use Honda ATF only.... but lots of people say MaxLife works great.

Maxlife is $17 for 4 quarts, this is more than that.
But good stuff.

I buy branded Honda DW-1 for significantly less from the dealer than I can find any licensed Dex VI around here. I wonder if the opposite is true, if full synth DW-1 fluid can be substituted for Dex VI in vehicles that call for it.

I have always had a favorable view of Idemitsu products ( havesome in a TLS flavor in a lexus right now). BUT: Molakule did a VOA on genuine Honda fluid vs. the Idemitsu honda and the add packs were NOTHING alike. It's not a "clone" fluid like people were thinking.

I find it to be better than DW-1, which is why I use it.
Pulls better. Perfect shifts.

I won't copy paste from the thread, but you can read the discussion here:

https://www.bobistheoilguy.com/foru...71227/re-three-atfs-analyzed#Post5271227

Here is my opinion, it's worth exactly as much as you're paying for it.

Yes the Idemitsu/Aisin/Maxlife fluids do not have the same analysis as Z1/DW1. If you want a clone of DW1, it doesn't exist, buy DW1.

It is my belief that just like motor oil, gear oil, coolant, etc, there is more than one way to get the job done. We have been told by Idemitsu that their H+ fluid has all the proper characteristics to work properly in place of DW1. How they do that and don't have matching chemistry, they haven't said. I don't particularly believe that with all the smart fluid engineers out there that whoever came up with the DW1 formulation had the golden key back in the mid 2000's as to the only way to make a fluid with those performance specs. It's been at least 10 years since DW1 came to market, I'm sure there's more than one way to skin that cat.

I also have spoken with the shop that did the rebuild for my wife's transmission in her now dead 2000 as to what fluid they recommend, a shop that rebuilds and ships Honda transmissions all over the US and has a great reputation. They use a 'multi-use' fluid in all of their rebuilds (Similar to Maxlife I expect, I have since forgotten the label on the drum at the shop), including the BAYA/MAYA 'fragile' V6 transmissions from the early 2000's. His opinion is that clean fluid is much more important than using DW1 exactly.

Me personally? I have switched over to the Idemitsu fluid because it can be had in a 5qt jug which I find more convenient than quarts. It has done everything I expect it to in my J-Series cars (And was working fine in the wife's rebuild until it got plowed by a cargo van and totalled).

As for Dex6, can't speak to it. Never considered using it in a Honda trans, although I'd be inclined to leave it to the GM stuff and pick up something that at least carries a 'suitable for' label. (Maxlife/Castrol/H+/Aisin/DW1).

That ATP stuff.....ehh, try it if you want, I'm a little leery about it and think I'll just stick with a regular fluid.


Not that we're discussing it here, but I certainly wouldn't ever go the other way and use DW1 in anything other than a Honda/Acura(and that one Saturn) transmission.
