Idemitsu ATF Type TLS-LV (WS) Automatic Transmission Fluid for Toyota/Lexus/Scion – 1 Quart, Case of 12 | Engineered for Optimal Fuel Economy and Enhanced Protection | Part Number: 30040091-75000C020

Excellent WS fluid for less than Toyota fluid. Idemitsu has been OEM supplier of Toyota WS so it’s probably the same stuff. I’ve used it in two 2021 4 Runners, 2016 RAV 4, and 2021 Camry. Works great no issues.

Bought and used in both my 2016 Avalon and 2020 Tundra. Both are running smoothly and quietly. The Tundra was at 65k, the Avalon at 85k. I believe this was the first fluid exchange for both and as I stated previously, both are running smoothly with good shifting and solid pedal throttle response. I plan on scheduling future fluid exchanges every 30k per Toyota's recommendation.

This transmission fluid worked very well for my application in a Lexus. No issues at all after drain and fill. There is no difference in feel or ride compared to Toyota WS fluid. This is a good option if one wants to get into synthetics.

Great transmission fluid

Totota OEM spec ATF at better price than the dealer. Flush every 60k miles if you want your transmission to last. No such thing as "lifetime fluid".

Its was perfect for my Scion, just like the original car its running smoothly again. Good quality and it seem just like the original can’t complaint will be buying it again when its time to change my fluid again. Thank you so much.

Suitable as an ATF replacement. 2013 GS350 awd

Great stuff, 4runner is good for another chunk of miles!
