What kind of transmission fluid does a Lexus GX 460 take?
The GX 460 uses Toyota/Lexus ATF WS (World Standard) automatic transmission fluid. Use Toyota Genuine ATF WS or an equivalent that clearly meets the WS specification.
The GX 460 is designed to run with the WS specification to ensure smooth shifting, proper lubrication, and long-term reliability of the transmission. Always verify the exact specification for your model year and market in the owner's manual or with a Lexus dealer, as specifics can vary by production run and region.
Specification and compatibility
Understanding the official fluid specification helps ensure you source the correct product and avoid potential transmission issues.
What fluid to use
Before listing options, note that you should source a fluid that meets Toyota/Lexus ATF WS specifications. The following options are commonly used by GX 460 owners and service centers:
- Toyota Genuine ATF WS (World Standard)
- Aftermarket ATF that explicitly lists "WS" or "ATF WS" on the label and meets Toyota/Lexus WS specifications
- Avoid fluids that are only Dexron III/VI unless the manufacturer or service bulletin confirms WS compatibility
Using a WS-spec fluid maintains the correct viscosity, shifting feel, and friction characteristics required by the GX 460’s transmission control system. If you’re unsure, consult your local Lexus dealer or a trusted mechanic with your VIN to confirm the exact specification for your year and region.
Maintenance notes
Service intervals and fill procedures are specific to model year and transmission type. The following guidance helps you navigate maintenance and fluid changes.
Before the list: Transmission fluid service should follow the official maintenance schedule in your owner’s manual or a dealer-recommended service bulletin. The steps below outline typical practice but may vary by year.
- Have the transmission fluid level checked with the vehicle on level ground and at the proper operating temperature, as specified by the manual.
- Use the correct fill procedure and pressure when adding or replacing fluid, ensuring no air pockets are trapped in the transmission.
- Replace the fluid at the recommended interval (the exact miles or kilometers vary by year and driving conditions).
- Consider a professional service with a dedicated transmission flush or drain-and-fill if indicated by the service manual, avoiding DIY flushes that could harm seals.
- Monitor for signs of transmission problems after a service, such as slipping, rough shifting, or warning lights, and address promptly.
Concluding guidance: Always rely on the owner's manual and dealer guidance for the exact interval and procedure. If in doubt, seek professional service to avoid potential transmission damage.
