Aisin transmission fluid

[smittyd174]

Has anyone used Toyota type IV fluid in a Aisin transmission. Its type iv meets jws 3309 specs. Less than 1/2 price of mopar brand. Mobile 3309 is almost impossible to find in Canada and its more expensive than the dealer. Just curious.

Amazon has 6 quarts of 3309 for $38.... is that a good price for you?

You might could use the Toyota fluid, but if it's not less than this....

Toyota T-IV is the same fluid as ASRC, as it’s all JWS3309 as mentioned.

I use Amsoil ATF in both my transmissions calling for it. Just did a drain and flush on the 4Runner yesterday, 203K.

What has always amazed me is that Toyota considers T-IV a lifetime fluid, even says so on the dipstick. Yet it’s only good for 30K in the AS69RC. I realize different applications but that’s a huge difference, especially for a non-synthetic fluid.

There is simply nothing fancy about this fluid, it’s just hard to find because most transmissions went away from the spec 15-20 years ago.

Interestingly, I missed changing the fluid at 30K miles on my 09 4500 and ended up having done at dealer at 60K miles... after figuring out what I did, I asked dealer to eval the fluid and wear on the transmission.... both were excellent. I know just looking at the fluid is entirely unscientific, but no neg wear signs of running the fluid at twice the recommended interval.

I changed my 17 Ram 5500 at the 30K mile interval and will continue to follow the recommended intervals.

I'll likely keep using 3309 as I purchased 2 cases to get proper 7.2 quart fill, which after overnight operating temp drain, landed right on the full mark on the dipstick.

All good info, thanks! Ron

Really confused now as I understood it it was not synthetic. Looking at that site it states
ALL AISIN Automatic Transmission and CVT Fluids are 100% Synthetic

Interesting indeed. I have see on their site in the past where it says ATF-0T4 is not synthetic.

As for the OP’s question the listed fluid for the AS69RC is T-IV from Aisin.

The Wife's Sienna appears to be OT4 according to their chart and states 100k service.

How are you guys doing the flush? Just draining the pan? Or flushing the torque converter too?

Just a simple drain and fill.

Is there a spin on filter ? or internal? or nothing?

There is an internal filter that gets changed out every other drain and fill, 60K, 120K, etc.

no one has figured out how to do a proper fluid exchange on the AISIN. Easy on the 68!

I bought the Aisin fluid from Rockauto.

It a heck of alot more in Canada around 180 for a case . I can get Aisin brand or Toyoto type 4 for $ 8 a quart. The dealer wants $17.

Wow... I guess I didn't realize how much more everything costs in Canada. Congrats on figuring a solution out that saves you. Do the trucks themselves cost way more there too?

....and no one should realllllllly be concerned with not doing the “improper fluid exchange” on the AS69RC as if one is relatively faithful to the supplied maintenance regimen, it will perform great for many, many, many miles. Not hearsay, not a rumor, not a speculation......just plain old FACTS.

Whew! I'm glad you posted that. I'll be creeping up on my 30K fluid drop, and thought I'd have to drill a hole in the converter

Yeah probably $10,000 depending on the truck. Its the tax that sucks but we don't need to buy health insurance . So you can pay the insurance companies or the government nobody rides for free.
