hey do they still make dexIII M1 syn? i cant find it anywhere. all i see are the M1 multivehicle [censored].. i need a dexIII bc i keep getting told that i cant go with DEX IV in my tacoma thats a DEXIII... argh... this is [censored] me off bc i dont want that multivehicle mess
 
Dexron-VI is fully compatible with Dexron-III(H) applications. In fact, you should avoid DEX/MERC products now as their contents are no longer regulated.
 
I found it at the local walmart.

Meets all dextron specs.

I've been using it in my saturns manual transaxle that calls for dexIII, with very good results.
 
If I remember right from this forum there are two different versions and they have recently changed the labeling. I don't think the website is current. Again going from memory the one you want is the one labeled Mercon V. It is the same as the old Dex III. The other is the Dex. VI.

Yes, Tones is correct you want the Mobil 1 with the Mercon V designation...it's probably almost identical to the old Dex-III formualation. You could also try Valvoline Mercon V its about 2 bucks/qt cheaper.

yeah everyone carries the the newer synthetic M1 multi-vehicle atf thats Merc V.. on the website the regular mobil multi-vehicle says its fine for dexIII application but it has no info on the syn form of the multi-vehicle.. can i still use the syn M1 multi-vehicle even though i have a dexIII transmission in my tacoma?? thanks fellas

Take note of what I bolded out in the quote...
 
DEXIV is for GM vehicles not for toyotas correct? the only synthetic atf i can get is M1 multi-vehicle and Castrol dexVI. thats it. or i can just stick with my maxlife dex\merc that i have been using. just wanted to switch to syn.
 
No, it's for ANY application that previously called for Dexron III.

And it's Dexron-VI, not Dexron-IV

are you sure? i asked in another thread and salesrep replied with a "NO" and artificialist said "Once the right HFM additive is blended into the ATF, I would use it."

Spoke with a very accurate source at GM and he assured me that Dexron-VI has been back-speced for applications that previously requires Dexron III(H).

Here's the caveat though. While GM has validated Dexron-VI on their hydramatic transmissions, Toyota may not have validated Dexron-VI in their units. However, theoretically Dexron-VI was built to be fully compatible with Dexron III applications so there shouldn't be a problem. I personally would use Dexron-VI because it's a far superior fluid.
 
I like DexVI... it's worked great so far in both my GM transmissions which call for DexIIIG.

Thing is, there is some disagreement on whether or not it's suitable for all previous dexron applications. IIRC, GM says that DexVI is good for all applications back to those calling for DexronII... but then there was some back-pedaling for a few applications that hadn't been thoroghly tested.

Also, Allison (which is no longer owned by GM) specifically says not to use DexronVI in older transmissions calling for DexronIII. They say that there could be seal compatibility issues. They reccomend a DexIII equivalent, which is still readily available... but no longer licensed. Yet their new transmissions are coming with DexVI standard.
 
That is why there is TranSynd ATF. It is thicker than Dex VI, but is still fully syn. It was also recommended by GM for Dex III use.
 
again all i can get in my area are these synthetics

castrol dex6
M1 multi-vehicle syn.

thats it as far as synthetics go.

-just got off the phone with a mobil rep and he said that the multi-vehicle formula does spec dexIII and is compatable with all dexIII transmissions including toyota and etc..

-he also mentioned that he would be skeptical about using dex6 bc its made for hydromatic transmissions ( i think i said that right)and toyota has not back spec'd it
