What transmission fluid for Toyota Yaris?
The correct transmission fluid for a Toyota Yaris depends on the model year and the type of transmission. In most modern Yaris models with a conventional automatic or a CVT, Toyota’s own fluids are recommended: ATF WS for automatics and CVTF WS for CVTs. If you own an older Yaris with a traditional automatic, Dexron II/III-compatible fluids may be acceptable in some markets, but you should verify the exact specification in your owner's manual or with a Toyota dealer.
Yaris generations have used different transmissions across regions, including CVTs in newer models and traditional automatics or manuals in others. This article explains how to identify your transmission type and which fluids are commonly specified, while emphasizing that the exact requirement should come from the official manual or VIN-based guidance.
Identify your Yaris transmission
Knowing the exact transmission type is essential to choosing the right fluid. Use these steps to determine what your car uses:
- Check the owner’s manual or the vehicle’s maintenance booklet for the transmission section, which lists the exact fluid specification.
- Inspect the transmission type on the vehicle (CVT badge, transmission code, or accompanying service labels); if in doubt, check the VIN with a Toyota dealer or online VIN tool.
- Note the model year and market, since Yaris transmissions differ by region and generation.
Identifying the correct transmission type helps ensure you use the proper fluid and avoid costly mismatches.
Fluid options by transmission type
The following guidelines cover the most common configurations found in Toyota Yaris models. Always confirm with the owner's manual or a dealer for your exact VIN.
- CVT (continuously variable transmission) in current Yaris models: Toyota Genuine CVTF, typically labeled CVTF WS (World Standard). This fluid is formulated specifically for Toyota CVTs and should be used instead of standard automatic fluids.
- Conventional automatic transmission (older Yaris models or specific markets): Toyota Genuine ATF WS (World Standard Automatic Transmission Fluid) or an equivalent that meets the fluid specification listed in your manual. Some older transmissions in certain regions may have accepted Dexron II/III-equivalent ATF if so specified by Toyota in that market; never assume compatibility without checking the manual.
- Manual transmission: gear oil that meets GL-4 specification (commonly 75W-90). Do not use ATF in a manual transmission unless the manual explicitly calls for it.
When dealing with transmissions that are not clearly covered by these categories, or if you are unsure about your exact model configuration, consult the owner's manual or contact a Toyota dealership to pull the precise specification for your VIN. Mixing fluids or using an incorrect type can lead to poor shifting, lubrication issues, or damage.
Special notes and maintenance tips
Extra care is advised when changing or flushing transmission fluid. CVT fluid changes are not the same as conventional ATF changes in terms of procedure and frequency, and some CVTs require a professional service to drain all fluid. If you’re replacing fluid in a CVT, follow Toyota’s official service procedure and use the exact CVTF WS product specified for your transmission. For automatics and manuals, follow the service interval in the manual and use the recommended quantity and fill level. If you’re working with a used vehicle or a vehicle from another market, VIN-based confirmation is strongly recommended to avoid incorrect spec fluids.
Summary
To determine the right fluid for your Toyota Yaris, identify whether your car has a CVT, a conventional automatic, or a manual transmission, then use the fluid specified by Toyota for that configuration: CVTF WS for CVTs, ATF WS for automatics, and GL-4 gear oil for manuals. Always verify with the owner’s manual or a Toyota dealer for your exact VIN and market, and avoid mixing fluids.
Quick reference by transmission type (overview)
The following quick references help you navigate common Yaris configurations, but verify against your manual:
- CVT: Toyota CVTF WS (World Standard CVT Fluid).
- Conventional automatic: Toyota ATF WS (or as specified in the manual; some markets allowed Dexron II/III equivalents if specified).
- Manual: GL-4 gear oil, typically 75W-90.
For the most accurate guidance, consult your owner’s manual or contact a Toyota service center with your VIN. A correct fluid choice preserves shift quality and transmission longevity.
What kind of transmission fluid does a 2009 Toyota Yaris take?
For a 2009 Toyota Yaris, the automatic transmission fluid is a "World Standard" type (Aisin JWS 3324) or an equivalent fluid like Dexron VI, while the manual transmission uses a 75W gear oil. Always consult your owner's manual for the most accurate and specific recommendation for your vehicle's transmission.
Automatic transmission
- Type: Use a "World Standard" automatic transmission fluid (ATF), which is also known as Aisin JWS 3324.
- Alternative: Many modern ATFs, like Dexron VI, are compatible with this specification and can be used. Check the fluid's specifications to confirm it meets the JWS 3324 requirement.
Manual transmission
- Type: Use a 75W gear oil.
- Specification: It should be a GL-4 or GL-5 rated gear oil.
Important considerations
- Consult the owner's manual: The owner's manual is the definitive source for your vehicle's specific needs.
