What kind of oil does a Toyota Hilux automatic transmission take?
The typical fluid for modern Toyota Hilux automatics is Toyota ATF WS (World Standard). However, the exact specification depends on your model year and transmission type, so check the owner’s manual or ask a Toyota dealer to confirm before servicing.
How to determine the correct ATF for your Hilux
To ensure you use the right transmission fluid, identify your Hilux’s transmission type and year. The required ATF can change between generations and regional specifications. Start by locating the exact transmission code or referring to the official service data for your VIN, then confirm with the owner’s manual or a dealer before purchasing fluid.
Common ATF options across Hilux generations
Below is a general guide to what has been specified across different Hilux generations. Use this to understand possible options, but always verify for your exact vehicle.
- Toyota ATF WS (World Standard) — widely specified for many modern Hilux automatics and often the default recommended fluid for recent model years.
- Toyota Type T-IV — used in some older Toyota automatic transmissions; confirm with your manual if this exact specification applies to your Hilux.
- Dexron family fluids (e.g., Dexron II/III/VI) — historically used in some markets as substitutes in older transmissions; not universally approved for all Hiluxes. Do not substitute unless your manual or dealer confirms compatibility for your VIN and transmission code.
In short, the safest approach is to use Toyota Genuine ATF WS for modern transmissions, or the exact specification listed for your specific Hilux. Avoid mixing different ATF types unless explicitly permitted by Toyota for your model.
How to verify and service correctly
Use the following steps to confirm the proper ATF and perform a service safely:
- Consult the owner’s manual for the exact ATF specification required for your Hilux’s year and transmission code.
- Identify your transmission code (via the service label on the vehicle, VIN-based service data, or the transmission housing) to match the correct fluid specification.
- Purchase the recommended fluid (typically Toyota Genuine ATF WS for modern models) from a reputable source and avoid mixing with other ATF types.
- Have the transmission serviced by a qualified technician, following the prescribed change interval and procedure in the manual.
Following these steps helps prevent shifting issues, wear, and potential damage from using an incompatible fluid.
Summary
The Toyota Hilux’s automatic transmission fluid depends on the transmission design and model year. For most modern Hiluxes, Toyota ATF WS is the standard specification, but always verify with the owner’s manual or a Toyota dealer based on your VIN and transmission code. When in doubt, use the manufacturer-recommended ATF and avoid mixing fluids. Regular, correct servicing supports smooth shifting and transmission longevity.
