Fluid specification for the RX450h
Details and guidelines that govern the fluid choice for this model's transmission are as follows:
- Fluid type: ATF WS (World Standard) designed for Toyota/Lexus hybrid transmissions.
- Compatibility: Use ATF WS or an approved equivalent that explicitly meets the WS specification.
- What to avoid: Do not substitute non-WS automatic transmission fluids in the transaxle (avoid options not rated WS).
- Service guidance: The RX450h’s eCVT service intervals and fill quantities differ from conventional automatics; refer to the owner's manual or a Lexus service advisor for exact capacity and intervals.
In practice, the official guidance is to use WS-grade ATF in the hybrid transaxle and to defer to a dealer or trained technician for any transmission service to ensure proper fill and sealing, especially given the unique setup of a hybrid eCVT system.

Bottom line: For a 2013 RX450h, ATF WS is the official recommendation. Always confirm the specification with the owner's manual and rely on qualified technicians for any transmission maintenance.
Summary: The 2013 Lexus RX450h requires ATF WS (World Standard) in its hybrid transaxle. Use WS-compliant ATF and follow the owner's manual for capacity and service intervals; consult a Lexus technician for any maintenance.

What transmission fluid does Lexus use?
The specific Lexus transmission fluid type depends on the model and transmission, but commonly used fluids are Toyota ATF Type T-IV for older models and Toyota ATF WS (World Standard) for newer, sealed transmissions. Always consult your owner's manual or a dealer to ensure you use the correct fluid for your vehicle, as using the wrong type can cause damage.
Common Lexus transmission fluid types
- Toyota ATF Type T-IV: This is a common fluid for many Lexus models with conventional automatic transmissions. You may also find third-party fluids specifically formulated to meet this specification, such as Idemitsu ATF Type TLS.
- Toyota ATF WS (World Standard): This is the fluid recommended for newer Lexus vehicles with sealed transmissions.
Important considerations
- Consult your owner's manual: The most reliable way to determine the correct fluid is to check your owner's manual for the specific "ATF" type required for your vehicle's model year and transmission.
- Avoid generic fluids: Do not use generic "multi-vehicle" transmission fluids unless they specifically state they meet the T-IV or WS specification required for your Lexus, as some generic formulas may not be compatible with Lexus transmissions.
- Use genuine fluids: When possible, use genuine Toyota/Lexus branded fluids to ensure the product is formulated to meet the exact requirements of your vehicle.
