I found Aisin WS fluid on Rock auto for $7.34 plus shipping. Is that a good price and is it the same fluid?

Aisin is a Japanese powertrain manufacturer. The largest in the world. They make a lot of transmissions for Toyota (and others). They are not a lubricant company. Neither is Toyota. Toyota ATF-WS is made by Esso or Exxon, and Aisin probably gets the exact same stuff and slaps a different label on it. Rockauto is a trustworthy source.


I wouldn't be surprised if the "WS" or "World Standard" trademark was licensed. Meaning that to be able to use this name on the label, the fluid has to meet specifications.

Well it should be as long as the company isn't lying and selling some fake thing with a fake bottle


Thanks Scotty 😕
