Atf Fluid

[Guest Tones]

If you notice from this link, the Mobil 3309 is also equivalent to Toyota type T-IV fluid.

Amsoil's ATF is a very good fluid and is an acceptable substitute for Toyota's Type T-IV and Saab's 3309. I believe it would be an acceptable substitute for the Volvo fluid as well. A quick email to Amsoil would confirm it. Significant savings over the Volvo fluid and probably a much better all-synthetic product as well.

I have 1999 S80 T6 with 144 000 miles on it. I do not have problem with the transmission, but I would prefere to flush the oil. I went to a local shop and they said that there is no drain plug and they cannot flash it. I guess I have to go to Volvo dealer. Also what kind of oil I have to use 3309?

Thanks

Your transmission takes Dexron III.

So I will be OK if I put Mobil Synthetic ATF? My local Volvo Dealer says that I should use only Volvo Synthetic, and what I understand here Volvo Synthetic is the same as Mobil 3309 not Dextron III. Sorry to question your answer, but I just would like to make sure.

Thanks

Rich, as usual, is correct. The online owner's manual for the 1999 S80 says the fluid for the automatic transmission is:

"ATF Dexron®III G"

Later model year S80s have, to the best of my knowledge, different automatic transmission set ups that require the 3309 formulation.

Later model year S80s

All S80s with a six cylinder, turbo or not, take the dexron IIIG or equiv. The newer S80s that have the 5 cylinder and a lpt have the trans that requires the 3309 specs fluid.

Thanks for the answer, but I was not able to find any Dextron IIIG? Who makes this kind of ATF? All I have found is Type A or H. No IIIG

Thanks

I remember reading somewhere that Dexron III-G is a new specification which has even stricter standards than the Dexron III-H specification.

My best guess is that the Dexron III-H spec oil should work, but let's wait for Rich's reply.

Guest,

A quick net search comes up with Shell, Valvoline, Castrol & Amsoil each offering an equivalent of Dextron IIIG (or Dexron as some mfrs call it).

FYI, I got a case of Mobil 3309 from Boncosky Oil (got their number from their website) for $47.94/case of 12, $25.00 to ship it to me. Did the flush on our '01 T5 today. B)

Honestly I am confused. I was searching the net and no luck with Dexron IIIG. Obviously it is an old spec ATF and it is replaced by H. What should I put in my 1999 S80 T6 transmission? I do not want to go to the dealer and pay big $$$. According to Rich I should not use Mobil 3309.

Any kind of help will be appreciated.

Thanks

Use the latest DEXRON III that you can get. H meets G specs, the higher always meets or exceeds the lower.

I spoke to Castrol and the answer was do not use Castrol Synthec Dexron III in Vovlo S80 1999. They also said tht this oil surpasses specification H and G. What I learned is tht GM4T65E trasmission is also used in Buick Reagal 3.8 from 1999 to 2002. In this case should I use Castrol Synthec Dexron III?

Thanks

Is it OK to put non Synthetic Dexron IIIG or H specification on S80 1999 T6?

[Bay13]

yes

After reading all the posts, here is what the Volvo dealership in Charlotte NC told me. I have a 99 S70 AWD. They said that my transmission took synthetic (everything on this post says dextron), but that the transmission doesn't ever need to be serviced. I said my fluid was looking dirty and he said that didn't matter. Can you believe that they are giving out that info?

Just my two cents.
