I’d like to get into a routine of doing a drain and fill every 15k miles on our new Mini (yields about 3 quarts). Fluid spec is JWS 3309 for the Aisin transmission. JWS 3309 is nothing fancy (mineral). There are many synthetics that are “recommended” for the JWS 3309 spec. Aisin or Toyota branded JWS 3309 fluid is about $6 a quart. What would you use? I’ve Castrol come up a couple times on various forums.

I can only say that I have used both Castrol IMV and MaxLife in vehicles that required 3309/T-IV with great success. I would buy whichever is the least expensive at the time of your D&F.

I used the Castrol IMV for a D&F and wasnt satisfied in my Mom's Fusion. Bought a case of Mobil 3309 and flushed it, been happy ever since.

We have a Lexus es which uses T-IV. After 100k miles of experimenting with various fluids, I am using 3309 and much happier.

I have used Maxlife, Castrol IMV, and Castrol High Mileage. 3309 gives smoother performance, with the Castrol HM being the 2nd best. The Maxlife and other newer low viscosity fluids were distinctly worse.

I have used Mobil 3309 sourced from Amazon. Buy it by the case of 12 bottles.

I should also add that I have used the Castrol TM HM and did not notice any differences between any of the 3 now that I've mentioned. All being good.

A 3309 equivalent will be thicker than something like Maxlife, Valvoline MVI etc.

I get Toyota T-IV at the local dealer for around $3.50 a quart.

Valvoline MVI almost as thick as T-IV.

Plenty of AW transmissions in the family so I've done "this" a lot.

Mobil 3309 IS a conventional fluid. Most don't know that. I found cases in Virginia years ago.

Amalie Super Universal Synthetic Transmission Fluid. Buy through the Amaliestore.com. Shipping is free over $39 last time I bought some. Their oils are real reasonably priced too.

Valvoline MaxLife Dex/Merc LV. The LV stands for Low Viscosity. Works perfectly. I bought 12 gallons once on an AutoZone 1/2 price sale. It's gone now.

I've bought cases of Toyota Type-IV at my nearest dealership.

Aisin sells a fluid through FCPEuroparts and eEuroparts.

The Amalie product is by far the lowest priced.

Never a problem with any of these.

Happy draining. "A clean transmission is a happy transmission providing it's not sad in the first place."

Are you a fluid scientist?

Who said that it is no fancy fluid, its on millions of vehicles and running just fine.

It is the best fluid speced for Toyota that calls for T-IV.

Yes it isn't a lifetime fluid but definitely a 60K fluid.
Yes XOM makes the 3309 (remember only XOM makes the T-IV/3309) and they are surely priced a dollar less than the dealership.

Castrol TransMax Full Synthetic ATF also meets JWS 3309 as well.

I have used both of these … but in my area the Castrol has been hard to find at times … and the individual quarts can cost more than jugs … going to migrate to Maxlife …
Have three vehicles that drain a gallon anyway

I've used Toyota and Mobil 3309 in my Tundra.

I once tried Red Line D4 (replaced most of the existing 3309/T-IV with D4), and it affected the shifting significantly. I left it in for 3000 miles, then went back with Toyota T-IV and Mobil 3309 again.

Rockauto also sells Aisin T-IV fluid, which I would use as well. Most of the fluids like Castrol IMV and MaxLife aren't approved for 3309, just recommended. They might be fine, but I won't deviate from approved fluids anymore after my experience with D4.

Pennzoil Platinum High Mileage Full Synthetic ATF has a JWS-3309 approval. I buy it at my local Shell distributor for $4.25/qt. PepBoys also carries it.

Pennzoil claims are one part, do they have a license much like Dexron/Mercon ... doubt it.

Used D6 on my Lexus and quickly dumped it when there were flares, the while idea of synthetic isn't cutting it. WS is just fine on the vehicle in high heat summers.
