AT spec. 3309

If you need a bunch, go to your local ExxonMobil distributor and order a case. I think the MSRP for 12 is $73, or $6.08 a quart. I have seen it online for $5-ish a quart but you have to pay shipping.

GM dealers also offer an equivalent, GM 9986195, as it is specified for the Pontiac Vibe's automatic transmission. That may be another place to look. Ford has an equivalent fluid in their Premium Transmission Fluid XT8-Q-AW that is used in Ford and Mazda six speed Aisin transmissions. Mazda just sells it as T-IV across the parts counter. Volvo's part number is 1161540. VW/Audi use it but I can't imagine getting it any cheaper from their parts department than a Ford, GM or Toyota dealership if you can't get it through a Mobil distributor.

Very few parts stores seem to carry the stuff.

I am pretty sure it is all the Mobil fluid, just rebranded. The standard for it is JWS-3309.

Make sure it is the right stuff as it does not react well with other fluids, apparently, I have heard "bad news" about it and Mercon V. The clutch packs bite it pretty quickly. Might be different with Dex/Dex equivalents.
 
For A Mazda CX7 with a 6 Spd. Aisin transmission. Factory manual states a refill of 7.6 quarts. I insist on using the Spec'd fluid and not labeled as Universal or "as-good-as or other such wording.
 
All of the fluids I listed are exactly the same, they are the 3309 fluid for Aisin-Warner transmissions. It's all specific to the same applications, just given a different part number depending on where you buy it. All of it is JWS-3309 fluid.

Good luck then. You are pretty much going to be limited to buying the fluid at a dealer( ie; Toyota, GM, Volvo, Mazda, Ford, etc... )under whatever fluid rating number they use.

As McGregoir told you it is all JWS-3309. Mobil is the only aftermarket fluid mfg I know of that offers it specifically as their 3309 fluid. The most common mfg referrence to that standard is Toyota T-IV fluid or just T-IV( my 08 GM vehicle with Aisin-Warner AF33 calls for T-IV ).

If you were to find an aftermarket fluid for that spec chances are it would be called T-IV. Haven't seen any out there that is just T-IV like you see with GM's Dex VI, Chrysler ATF+4, Toyota WS, etc... It is all being offered under the multi-spec fluids now other than the Mobil 3309 stuff. This stuff has been around so long it is now far behind current fluid technology thus multi-spec fluids can more than adequately handle it.

This is an older conventional fluid and modern multi-spec ones would be better. Countless thousands have run the likes of Amsoil and Royal Purple universal/multi-spec ATF's in the T-IV/3309 tranny's with great success. I understand your desire to stick with the spec'd fluid but it is an older fluid spec that is now covered under the multi-spec category in the aftermarket other than the Mobil 3309.

So, you can go to a dealership and buy an OEM version, buy the Mobil 3309, or buy a multi-spec aftermarket fluid. Any will work. If you are truly worried about warranty or compatibility then drive on down to the Mazda garage and buy the JWS-3309 fluid from them.

Yes- I am concerned about warranty issues and I keep my vehicles for 125,000 miles or so. I am very vary of one-size-fits all when it comes to ATF. I will stick to the Mazda dealer I guess unless I see 3309 on the container. Thanks all for the information. Ed

Yup, going to swap my Aisin AF33 over to RP as well.
 
Is the 3309 spec actually synthetic, or even a blend?

I see that pretty much noone makes it except Mobil, and they don't say its synthetic, or even a synthetic blend. I wonder if Mobil actually makes it for the OEMs as well?

As for switching to another spec, or multi-spec fluid. I've read some horror stories of mazda6 owners who have the 6 speed Aisin A/T who have had Dexron/Mecron put in and its absolutely wrecked their tranny. I'm pretty wary about any multi-spec fluid.

I've had previous Chrysler products as well, which didn't like to use anything but ATF variety. So I guess that makes me even more wary.

The friction modifier in the 3309 reacts with something in Mercon V fluids is what I have hear. Destroys the clutches.

3309 is mineral based and highly friction modified, it can be used in place of Dexron-III but not the other way around, Aisin transmissions are picky.

Chrysler transmissions, especially from the ATF+3 and A604 issues onward, are also very particular about what they will and won't work with.

I would not doubt Mobil making it for everyone, although when I looked, Ford says their fluid was made in Canada. Castrol has a big blending plant in Toronto, and Ford does a lot of business with BP, so I was thinking that, or maybe Petro-Canada who makes all of GM's factory fill transmission fluids for Dexron VI now. Does anyone know where the Mobil 3309 is made? Esso sells it in Canada as Esso 3309, so it could possibly be made here, as well.

Anyways, with so much 3309 spec'd fluid out there across the parts counter or from a Mobil distributor, I would just use the right stuff and not worry. How often do you actually work on your transmission or how much money do you have to put into it for it to be a really big deal? Transmissions aren't cheap and considering how little maitenence they take to keep reliable, might as well use the specified stuff and forget about it.
 
The issue is 3309/T-IV is not that great of a fluid to start out with. If you can run a synthetic that will work why not do it?
 
astraelraen You may already know, but multivehicle does not equal Dexron/Mercon

Multivehicle will work for Dex/Merc applications, but a specification that calls for 3309 fluid will not work with Dex/Merc fluid as you mention. Don't know the specifics, but I would not use a multivehicle fluid just because it says multivehicle. I would look for the 3309 support before using it in my 3309 application.

This is my question exactly.

The only reason that I can find is that Aisin trannys are picky, and I don't want to have to rebuild my 5000 mile brand new tranny in
The reason I speculate Mobil makes all the 3309 is that no other manufacturer makes it specifically. Even Castrol has a blend that says it will work for 3309 vehicles. But it isn't specifically branded 3309, or TI-V, or whatever.

I would simply like to find a synthetic source of 3309, but I don't see that happening. From a price point, 3309 is pretty expensive for a base mineral/dino oil pack. Maybe the friction modifiers, etc that are specific to the 3309 spec don't work with synthetic oils?

If a multi spec fluid mfg lists T-IV( or whatever spec you want to use )on their bottle chances are it has been fully tested to meet those requirements and will work in the application without problems. In our letigious society I doubt they would say it is okay to use their product in a tranny calling for T-IV if it would cause a problem. I just don't see them not covering themselves before making such a claim?

T-IV has been out for a LONG time and thus there most certainly are countless thousands of folks who have run multi-spec fluids without issue. There is even a guy in this thread who has run Royal Purple MaxATF which is multi-spec in his Aisin tranny with no problems. I honestly do not see any issues with it( myself anyway although I am not a fluid expert ).

I am pretty picky about making sure I use the right thing in my vehicle however. I am not an advocate of OEM fluids per say though. I think they are over priced and of mediocre quality at best as a rule. Give me a premium aftermarket fluid that meets/exceeds the OE requirements and I go that route. I will run RP MaxATF in my GM Aisin AF33 tranny calling for T-IV( 3309 ). I forsee no mechanical issues nor any type of incompatibility issues whatsoever.
