What kind of oil does a Toyota ATF take?
The short answer is: most current Toyota automatic transmissions use Toyota ATF WS (World Standard). Some older Toyotas use DW-1, and a few very early models may require Type T-IV. Always verify with your owner's manual or dealership before refilling.
Understanding Toyota ATF types by era
These are the main categories you’re likely to encounter, along with where they apply in Toyota’s lineup. Knowing the right specification helps prevent shifting problems and transmission wear.
What WS means for your vehicle: WS stands for World Standard and is designed for a broad range of Toyota automatics and many hybrids. It provides refined shifting characteristics and temperature performance across modern transmissions.
DW-1 and T-IV legacy notes
DW-1 is the update that replaced older T-IV in many models. Some late-models and certain markets may still tolerate T-IV in older units, but treat it as legacy and verify with your manual.
- Toyota ATF WS (World Standard) — the default specification for many Toyota models built in the 2010s through today, including most Camry, Corolla, RAV4, Highlander, Sienna, and many hybrids.
- Toyota ATF DW-1 — common for many older Toyotas and some 2000s-to-early-2010s models; gradually replaced by WS in newer vehicles.
- Type T-IV — an older spec used on very early Toyotas; largely out of use in modern models.
- Dexron III/VI compatibility — some services reference Dexron variants as a temporary substitute, but Toyota generally requires WS or DW-1 as specified for the model; always check the owner’s manual.
Understanding these categories helps you buy the correct fluid and avoid damage from mismatched ATF chemistry. When in doubt, default to Toyota’s current official specification for your car and consult a dealer or qualified technician.
How to determine the exact ATF specification for your Toyota
To ensure you buy the right ATF, identify your vehicle’s exact specification using official sources and vehicle-specific data. The following steps guide you through the process.
- Check the owner’s manual and the under-hood label for the exact ATF specification (WS, DW-1, or T-IV).
- Inspect the transmission fill cap or dipstick (if present) for the stamped ATF type or compatibility notes.
- Enter your vehicle’s VIN on Toyota’s official service portal or contact a Toyota dealer to confirm the recommended ATF type.
- Do not mix ATF types if you’re topping up; if the current ATF is unknown, seek professional service to drain and replace with the correct specification.
Getting the specification right saves you from shifting issues, heat problems, and accelerated transmission wear. If you’re unsure, a quick call to a dealer or a trusted service shop can prevent costly mistakes.
Maintenance tips and best practices
Maintaining the proper ATF and transmission condition is essential for longevity and smooth shifting. Here are practical guidelines to follow.
- Use the ATF specification recommended for your vehicle (WS, DW-1, or as otherwise specified) and avoid mixing different types.
- Follow the manufacturer’s change intervals in the owner's manual; many Toyotas use fluid life tests and do not require frequent changes, but consideration for service life varies by model.
- When performing a fluid change, decide between a drain-and-fill versus a full fluid exchange based on transmission type and service history; a professional service may be preferable for complex jobs.
- Choose OEM or Toyota-approved ATF fluids to ensure correct viscosity, detergents, and additives.
- If you notice slipping, harsh or delayed shifting, unusual noises, or overheating, have the transmission inspected by a qualified technician.
Following these practices helps keep the transmission healthy and avoids cross-contamination from incompatible fluids.
Summary
For most modern Toyota models, ATF WS is the standard. Older vehicles may require DW-1, and very early Toyotas might use Type T-IV. When in doubt, consult the owner’s manual, the under-hood sticker, or a Toyota dealer to confirm the exact specification before purchasing or adding transmission fluid.

For modern Toyotas (roughly 2006 and newer)
- Toyota ATF WS: This is the modern, low-viscosity fluid designed for current Toyota, Lexus, and Scion vehicles.
- Official part number: You can find this fluid under the part number 00289-ATFWS from Toyota.
- Alternatives: Some premium aftermarket fluids are formulated to meet the WS standard, but it is crucial to ensure they are certified as WS-compliant, not just "suitable for use".
For older Toyotas (roughly pre-2006)
- Toyota ATF T-IV: This is the correct fluid for many older models and is the replacement for legacy fluids like T, T-II, and T-III.
- Check your manual: It's essential to verify the specific type required by your vehicle's manual.
For Toyota vehicles with Continuously Variable Transmissions (CVTs)
- Specialized CVT fluid: Some Toyota CVTs require a specific CVT fluid, such as TC or FE, which is different from standard automatic transmission fluid (ATF).
- Check your manual: Always check your owner's manual to ensure you are using the correct type for your specific CVT.

Important considerations
- Use genuine fluids if possible: Toyota transmissions are designed with specific friction characteristics, and the genuine Toyota fluid is formulated to match these requirements precisely.
- Avoid universal fluids: Using a universal ATF can lead to issues like rough shifting, overheating, and accelerated wear because the friction modifiers may be different from what the transmission was designed for.
- Warranty: Using the wrong fluid could potentially void your transmission's warranty.
What kind of transmission fluid do I need for a Toyota?
ATF T-IV ( Type 4 Automatic Transmission Fluid) for all automatic transmissions which require ATF T, T2, T3 or T4. Do not use this fluid if your manual states your transmission uses Dexron or ATF WS! Designed, tested and approved by Toyota R&D. Special additives protect against corrosion and excessive wear.
