Toyota WS Transmission Fluid Alternative

Are there any good Toyota WS transmission fluid alternatives out there?

Yes, many reputed brands with alternate products are just as reliable such as Valvoline, Havoline, RedLine, etc.

However, do Toyota owners need to stick to OEM-approved fluid, or can they switch to equivalent options? I know it’s a hard question for many Toyota owners.

Luckily, this article will compare the OEM Toyota WS fluid with some good aftermarket substitutes. You will also see how each of them performs under real-time testing.

Let’s get started!

About Toyota WS ATF Specs

Toyota WS fluid was released in 2002 with the specifications JWS-3324 or NWS-9638. It is not backward compatible with older Toyota lubricants. Virtually all Toyota vehicles manufactured from 2014 with automatic transmissions use the WS fluid specification. It is a high-performance oil, and it lasts pretty long – up to 100,000 miles (according to a Toyota TSB).

However, since it is an OEM oil, the Toyota WS fluid is pricey. Hence, some Toyota vehicle owners lookout for cheaper universal fluids with the same specifications, JWS-3324.
