Hello friends,

Please where can I buy synthetic Dextron III ATF. My car atf dipstick says Dexron II or Dexron III. I would prefer a synthetic atf. Can I buy a dexron VI atf and use it on my ride when it clearly says dexron II/III.

Contributions please.

Thank you so much

DECOtech:


You are smarter than the vehicle manufacturer, abi?

sultaan:


Explain that please not sure if you meant car, fluid, or licensee of Dextron

A car is a major investment, if the vehicle breakdowns in the middle of nowhere, the expense and inconvenience can be high. You asked a good question, so that your decision will be rational. So I am going to see if I can help you lay the facts and help you come to a conclusion!
When was your vehicle manufactured?
What was the applicable Dexron standard then?
If your vehicle were manufactured today, would the manufacturer uses an outdated/withdrawn Dexron standard (assuming it did not join the bandwagon of creating its own fluid for its own type of car)?
What is the meaning of backward-compatible?
If you needed to replace an ECM would you get the old part (which has the same part number as the failed part) or the updated part (which has an incremented part no)?
Anywhere, this is the most authoritative source I can point to http://www.archivedsites.com/techlink/2009/05/
Just remember that the licenses for Dexron III were withdrawn as far back as 2005 or 2005 and so anything can claim to be Dexron III, there is no check, unlike Dexron VI.

Hope I have been useful!
SHAMELESS PLUG - I can get the fluid for you within the month if you so desire!

You don't state what your vehicle is, or it's year of manufacture.

However...if it was built after August 2004 (as I suspect it was) I would go with Dexron IV. Dexron III is old hat, I can't remember when last I used it in any of my customer's vehicles. That is Volkswagen Golf III era, and even with those, I use Dexron IV. The old Dexron III does NOT aid heat transfer as well as is ideal, and excessive heat is one of the most common causes of failure.

If Dexron III is all you can find (and you can vouch for it's authenticity, then by all means use it. But I personally would use something way more advanced. Someone here has even offered his assistance in procuring Dexron IV. I would seriously consider taking him up on his offer.

It's your call!

thanks for helping out. Its a 2000 Toyota sienna, 1MZ-FE, 3.0Litre, v6.

Try dis.

sultaan:


Dex VI might still be better than that.I will not recommend you use those Nigerian labelled Dex III they are not certified.
Basically nobody knows what is in there its possible they are good but no one is checking the manufacturer if they still meet the spec.

IdaraCHODB:

Please note it is not exactly correct to say that Type IV and Dexron III are interchangeable, because Type IV is a highly friction modified fluid that plain Dexron III is not.

I wonder why on earth one should punish a transmission that was built to run Dexron III or its equivalents ( read that to mean Dexron VI) with Toyota Type IV. I don't think it is wise. Personally i don't recommend it and I would not do it.

If your transmission dipstick reads Type IV then it means you are using an Aisin Warner transmissions which is a bit selective as far as ATF is concerned , so you must stick to Type IV or its equivalents like Mobil 3309 or AMSOIL Signature Series Multi-Vehicle Synthetic Automatic Transmission Fluid, but if it says Dexron III, then GM has made it pretty clear and even Toyota cannot contradict the fact that you can and should use use Dexron VI which is a much better fluid than Type IV or even Dexron III.

Please note that Type IV is not synthetic, it is conventional so please shorten the drain intervals if you want the transmission to last long, and if decide to use Dexron III when it specifies Type IV be ready for transmission slipping, and the expense of changing the transmission sooner than later

Quote with modifications: "If you fill one of these Aisin Warner transmissions in your Toyota Sienna with any other ATF than Type IV, you will need a replacement transmission within 5000 to 6000 miles, but this does not apply to a Sienna that specifies Dexron III? I seriously doubt it!"
See my source: www.motor.com/article.asp?article_ID=723

Indeed here is proof that Toyota has been known to specify two types of fluid for the same transmission not just in the Sienna:

What this tells you is that should you ever need to do a transmission transplant take note of what is written on the dipstick so you don't exchange or replace the wrong transmission for your application! And if you do, then change the sort of ATF you use immediately thereafter

nurey:


Do you mean we can interchange Dextron III with Dextron VI or is it Dextron IV

IdaraCHODB:


Yes, You can use Dexron VI in place of Dexron III.

Dexron VI was such an improvement that GM skipped IV, V and went straight to VI

You can confirm for yourself in several places online including Wikipedia

This year will make Dexron VI ten years old, from all the discussion on this topic both on and off this thread around about nairaland, I can see why transmissions don't live long in Nigeria
