What kind of oil does a Toyota Yaris gearbox take?
It depends on the gearbox installed in your Yaris. Manual gearboxes typically use GL-4 gear oil (commonly 75W-90); automatic transmissions usually require Toyota ATF WS; CVTs (including the hybrid’s e-CVT) use a dedicated CVT fluid (CVTF), often specified as Toyota CVTF Type WS. Always verify with your vehicle’s manual or dealer for your exact model year and market.
Understanding the Yaris gearbox fluids
The following guide outlines the fluids typically recommended for each Yaris transmission type. Exact specifications can vary by year and market, so always check the official documentation for your car.
- Manual transmissions: 75W-90 gear oil that meets API GL-4 specifications (often listed as GL-4 75W-90). Some markets may use other GL-4 or GL-5 formulations; always follow the manual.
- Automatic transmissions: Toyota ATF WS (World Standard) is the common specification. Some older or region-specific models may have compatibility with Dexron-type fluids, but WS is the standard recommendation for most Yaris automatics.
- CVT/e-CVT transmissions: Toyota CVTF (the dedicated CVT fluid). In practice, this is typically a WS-family CVTF or an equivalent CVTF specified in the owner’s manual; do not use conventional ATF in a CVT unless explicitly approved by Toyota for your model.
Using the exact fluid specification for your Yaris’ transmission is critical for smooth shifting and longevity. If you’re unsure, consult the owner’s manual or a Toyota dealer or service center.
How to confirm the correct fluid for your car
Use these steps to confirm the precise fluid type for your specific Yaris model and market.
- Check the owner’s manual or service booklet for the recommended transmission fluid specification for your exact model year and region.
- Look for a transmission code or model code on the transmission itself (often stamped on the case or listed in service documentation) and cross-check with Toyota’s official specs.
- If the manual isn’t available, contact a Toyota dealership or official service center with your VIN to verify the correct fluid type.
- When replacing or topping up, use only the fluid type specified by Toyota for your vehicle; avoid mixing different fluids or using non-specified products.
Note: CVT and e-CVT systems are particularly sensitive to fluid type; using the wrong CVT fluid can lead to transmission damage or reduced performance. Always follow the manufacturer’s guidance.
Summary
For the Toyota Yaris, the gearbox oil depends on the transmission type: manual gearboxes use GL-4 75W-90 gear oil; automatic transmissions use Toyota ATF WS; CVTs use a dedicated CVTF (often CVTF Type WS). The exact specification can vary by year and market, so always verify with the owner’s manual or a Toyota dealer before purchasing or servicing.
