What transmission fluid does a Toyota Highlander take?
Most modern Toyota Highlanders use Toyota ATF WS (World Standard) for the automatic transmission. Older models may require an older Toyota ATF specification or a Dexron-compatible fluid, so always verify with your owner's manual or the transmission code label.
This article explains the transmission fluid requirements across generations and how to confirm the exact specification for your particular Highlander.
Fluid choices by generation
Note: The Highlander has used several different transmissions over its history. The following overview provides typical guidance, but the exact specification should be confirmed for your VIN and transmission model.
- Gen 1 (2001–2007): The first-generation Highlander used a 4‑speed automatic. Fluid requirements varied by year and transmission code, with older Toyota ATF options and Type T-IV-era fluids commonly referenced. Always check the owner's manual or the transmission tag for the correct specification.
- Gen 2 (2008–2013): The 5‑speed automatic in this generation is generally listed with Dexron‑II/III or Dexron‑III‑compatible fluids in many references, though some markets and trims may differ. Confirm the exact spec for your vehicle before topping up.
- Gen 3 (2014–2019): Most models in this generation align with Toyota’s newer standards and typically require Toyota ATF WS for the 6‑speed automatic.
- Gen 4 (2020–present): The current-generation Highlander uses an 8‑speed automatic with Toyota ATF WS as the standard fluid specification.
Concluding: For the vast majority of newer Highlanders, ATF WS is the correct choice. If you’re working with a very early model or a VIN with a unique transmission code, consult the manual or contact a Toyota service advisor to confirm.
Hybrid considerations
Highlander Hybrid specifics
Hybrid variants use a different transaxle arrangement and fluid specification. Toyota typically requires a fluid compatible with the hybrid transaxle, and many guides point to ATF WS as the applicable fluid, but you should verify the exact specification in your hybrid’s manual or with a Toyota technician to avoid mis-specification.
How to confirm the exact specification
If you don’t have the manual handy, use these reliable sources to confirm the right fluid for your Highlander:
- Check the owner’s manual or the official Toyota website for your model year and transmission code.
- Inspect the transmission dipstick or the service label under the hood or on the transmission pan for the specified ATF type.
- Contact a Toyota dealer or certified service center with your VIN for a definitive recommendation.
Using the correct fluid is essential for smooth shifting and long-term reliability. If in doubt, opting for Toyota ATF WS is a safe, widely compatible choice for modern Highlanders, but always verify against your specific vehicle.
Summary
In most cases, Toyota Highlanders from the latest generations require ATF WS (World Standard). Older generations may call for Dexron‑family ATFs or other Toyota specifications, so verifying via the owner's manual, VIN, or dealer is essential. Proper identification and using the correct fluid helps preserve shift quality and transmission durability.
