Is Toyota Atf Ws Synthetic

For automatic transmissions with or without a slip-controlled lock-up clutch system, ATF WS is a wholly synthetic, low viscosity fluid. designed specifically for 6 speed automatic gearboxes in TOYOTA and LEXUS cars with AISIN-WARNER automatic transmissions. minimizes friction in automatic transmissions to maximize fuel efficiency.

All components of the transmission system are fully protected with ATF WS, which also ensures dependable performance even under heavy loads. better gear changes and automatic transmission response. It complies with all AISIN-WARNER automatic transmission specifications for WS fluid in Japanese, American, European, and other OEMs.


It is advised to use WS in TOYOTA, LEXUS, VOLVO, and other 6 speed AISIN-WARNER automatic transmission systems that were manufactured in 2004 and later. suitable for usage in many hybrid CVT TOYOTA & LEXUS vehicles.


Where WS fluid is required, ATF WS satisfies or exceeds OEM warranty requirements. TOTACHI promises complete adherence to the written requirements listed on product labels.

What does WS for the transmission fluid of a Toyota mean?

Toyota’s “World Standard” automatic transmission fluid is Genuine Toyota ATFWS. designed especially for Toyota sealed automatic transmission use. gives the best frictional performance and durability for long-lasting, continuously smooth shifting.

What is the shelf life of TOYOTA WS fluid?

The automatic transmission fluid never needs to be changed under “Normal” driving conditions, according to the Scheduled Maintenance Guide of a 2018 Toyota Camry with WS “Lifetime Fluid” and an 8-speed automatic transmission; however, there are Additional Maintenance Items for Special Operating Conditions:


  • Transport cargo and passengers within the tire and loading information label’s suggested ranges.
  • driven within permitted driving limits on appropriate road surfaces.

The automatic transmission fluid never has to be changed when driving under “Normal” conditions.

  • Making use of a car-top carrier
  • lengthy distances driven at low speeds or with a lot of idling, such as for delivery or law enforcement purposes.
  • Towing when driving
  • heavy loading of vehicles

Replace the automatic transmission fluid and filter every 60,000 miles (96,560 kilometers) or 72 months under “Special Operating Conditions.”

Is WS a specific kind of transmission fluid?

For contemporary 6- and 8-speed Aisin-Warner automatic transmissions, such as the TF-80 and TG-81 found in many late-model Volvos, Aisin type WS (“World Standard”) fluid is the factory fill ATF. Additionally, some later 5-speed automatic AW50 and AW55 transmissions, including those in late S40 IIs, V50s, and C30s, call for this fluid.

This fluid was designed by Aisin-Warner particularly for their transmissions and is not interchangeable with other ATFs like Dexron III or VI. It has a unique low-friction, low-viscosity recipe.

Is AISIN WS synthetic?

The largest producer of automatic transmissions in the world, AISIN, offers OE transmission fluid formulas used by automakers in the aftermarket.

  • ATF and CVT fluids for AISIN and other automatic and continuously variable transmissions are specifically developed for the friction material and pressure settings.
  • Excellent flow and temperature characteristics provide judder-free engagement in all conditions.
  • ALL AISIN CVT and automatic transmission fluids are 100 percent synthetic.

What distinguishes the TOYOTA ATF WS from the ATF T-IV?

In a blog post similar to this one, we discussed when to replace your differential and transfer case fluid as well as when we advise doing so. If you like this post, you should check out that one as well.

Toyota, Lexus, and Scion used T-IV (pronounced tee-four) and WS transmission fluids for their automatic and hybrid trans-axles in late model, 2001+ cars (short for World Standard).

Starting in the early 1990s, T-IV became the preferred transmission fluid for Toyota and Lexus automatics, displacing Dexron III. T-IV, a normal, non-synthetic fluid, needs to be replaced every 30 or 60 thousand miles, depending on the application, and it also needs to be inspected every 15 thousand miles. Simple draining and refilling of the fluid stored in the transmission oil pan constitutes the replacement process, which is tool-free. For this application, T-IV transmission fluid needs to be changed every 30k miles in the Prius from 2001 to 2003. In these early Prii, the fluid works to stop corrosion of the internal hybrid trans-axle drive windings.

If the transmission fluid has never been changed, should I change it now?

You may or may not be aware that, like all other fluids in vehicles, transmission fluid needs to be changed at regular intervals. There are very few that don’t need this kind of maintenance, like a finished sealed device without a mechanism to drain the fluid. Many are still functional, though.

It can harm the transmission and shorten its lifespan if you forget to change your fluid or, worse, if you wait until you start experiencing transmission problems. Even if the transmission wasn’t slipping before, replacing the fluid with new fluid can cause the transmission to slip if it has never been changed before. This is so that the gearbox can still shift gears because the old fluid will have clutch material in it from being there for a long period.

So, do you need to replace the gearbox fluid? How frequently should you replace it?

If everything is functioning properly inside the transmission, changing your fluid cannot harm the transmission on its own. If your clutches are already worn down or damaged from use, the problems start to show themselves when you change the fluid. If the fluid is changed after it has already been worn out. This may result in slippage. The previous fluid had been grittier to enable better gripping and contained particles that really assisted moving. Since new fluid lacks this component and may not grip as effectively, slippage may result.

Therefore, even though a change in fluid may cause the transmission to have problems, those problems were previously present; the fluid change only made them apparent.

Is it necessary to replace the transmission fluid to the international standard?

Every 60,000 to 100,000 miles automatically Most manufacturers advise changing your gearbox fluid every 30,000 to 60,000 miles if you drive a manual. The range can often be increased to 60,000 to 100,000 miles if you have an automatic. It is safe to change your fluid early.
