Hi sir,
https://www.walmart.com/ip/Valvoline-MaxLife-Multi-Vehicle-Automatic-Transmission-Fluid-1-Gallon/15125768
I've bought this ATF for my 2006 Toyota Harrier 350G (Lexus RX350) On the ATF stick I've read WS. But This bottle also has WS on it.
Is this good for my car?

As long as it says compatible to "Toyota WS."

You should only be using Toyota WS Automatic Trans Fluid.

I completely agree, purchase the Toyota WS Trans Fluid. Best way! Do not use anything else.

NAhhh. If it says compatible or direct replacement on the can - it is. They got lawyers who won't let them do it if it is not.

Honestly you should have used Toyota World Standard (WS) for your RX350. The universal one you picked up will work but you are risking the savings in fluid costs vs a full tranny re-built. Unlike motor oil, OEM ATF are made to the manufacturer viscosity specs. Buying a third party brand will come close to the viscosity but not perfect.

Valvoline states, it works on Type T, T-3 and T-4.

I bought my RX330 used with 160k. All seemed good except for the trans fluid was black and smelled burnt. There is a noticeable lag/slip from 2-3. Because the rest of the car was in like new condition, I decided to purchase fully expecting the transmission to need replacement just like in our Highlander. We dropped the pan and did a full flush with Royal Purple ATF. I'm over 200k now and the lag/slip has reduced. So I say if the warranty is important to you, stick with the Toyota WS. As for me, I'm sticking with the Royal Purple.
