What kind of transmission oil does a 2007 FJ Cruiser take?
The 2007 FJ Cruiser's automatic transmission uses Toyota ATF WS (World Standard) fluid, while the manual transmission, if equipped, uses a 75W-90 gear oil that meets GL-4 specifications. This article outlines the official recommendations and practical notes for both transmission types.
Automatic transmission fluid (for the 2007 FJ Cruiser with automatic transmission)
Below are the official guidelines and practical notes for the automatic transmission fluid used in most 2007 FJ Cruisers.
- Primary recommendation: Toyota ATF WS (World Standard) automatic transmission fluid.
- Do not rely on older Dexron II/III or Mercon fluids as the primary fluid; they are not the official WS specification and could affect shifting quality and longevity.
- If ATF WS is unavailable locally, contact a Toyota dealer or a trusted service center for an approved WS-equivalent or recommended substitute; avoid mixing fluids from different specifications.
In everyday maintenance, always confirm with the owner’s manual or a Toyota service advisor for the exact specification and service interval before refilling or servicing the transmission.
Manual transmission fluid (if your 2007 FJ Cruiser has a manual gearbox)
For the manual gearbox, use a high-quality gear oil that meets GL-4 specifications, typically a 75W-90 grade. Toyota manuals commonly require GL-4 compatibility to ensure proper shifting and gear life.
- Recommended grade: 75W-90 gear oil meeting GL-4 specifications (some models specify Toyota Genuine Gear Oil GL-4 75W-90).
- Avoid fluids that are GL-5 only, unless the manual specifies GL-5 compatibility; GL-4 compatibility is generally preferred for Toyota manuals.
- Always check the owner's manual for the exact specification and service interval for your VIN and transmission version.
When in doubt, consult a Toyota dealership or a qualified technician to confirm the correct manual transmission fluid specification for your vehicle.
Maintenance tips and service considerations
Useful reminders to keep your transmission in good condition and avoid common mistakes.
- Follow Toyota's stated service intervals for fluid replacement; many owners perform a drain-and-fill or full pan drop at intervals such as 30,000–60,000 miles depending on driving conditions and tow usage.
- Use only the recommended fluid for your transmission type and avoid mixing fluids with different specifications.
- When topping up or refilling, ensure the engine is warm and the vehicle is level to obtain an accurate fluid level reading.
Regular checks and adherence to the recommended fluid type help prevent shifting problems and extend transmission life.
Summary
For a 2007 FJ Cruiser with an automatic transmission, use Toyota ATF WS (World Standard). If your model has a manual transmission, use 75W-90 gear oil that meets GL-4 specifications. Always verify the exact specification in the owner’s manual or with a Toyota dealer, and avoid mixing different fluids. Following the recommended maintenance intervals will help ensure smooth shifting and longevity of the transmission.
