The correct transmission fluid for a Scion xB depends on the model year and whether the car has an automatic or manual transmission. In most cases, newer xB models use Toyota ATF WS (World Standard), while older automatics may specify Dexron II/III compatibility. Manual transmissions typically use GL-4 gear oil or a Toyota MTF. Always confirm with the owner’s manual or a dealer for your exact vehicle.
Automatic transmission fluid
To help you navigate the variations, here is a quick breakdown by era and common specification. If you are unsure, starting with the manufacturer’s recommended fluid is the safest approach.
Common specifications by generation
- First-generation Scion xB (approximately 2004–2006) with a 4-speed automatic: Dexron II/III compatible ATF is commonly acceptable; some manuals may list Toyota Type T-IV as an option.
- Second-generation and later (approx. 2007–2013) with a 4-speed automatic: Toyota ATF WS (World Standard) is commonly recommended; Dexron III compatibility may be acceptable in some cases, but WS is generally preferred.
Conclusion: Always verify the exact specification for your year and transmission code in the owner's manual or from a Toyota service advisor. If WS is listed, or if Toyota specifies WS for your VIN, use ATF WS.
Manual transmission fluid
The Scion xB’s manual transmission typically requires a GL-4 rated gear oil or Toyota MTF. The exact viscosity (for example 75W-90) and whether to use MT fluid can vary by year and trim, so refer to the owner's manual or a dealer for the precise specification.
Common recommendations for manuals
- 5-speed manual transmissions commonly use GL-4 75W-90 gear oil or Toyota MTF as specified in the manual.
Conclusion: Using the wrong manual fluid can lead to gear wear or shifting issues, so confirm the exact specification for your model year.
Summary
In short, the Scion xB’s transmission fluid depends on year and transmission type. Most modern automatics use Toyota ATF WS, while older automatics may call for Dexron II/III compatibility. Manual transmissions usually require GL-4 gear oil or Toyota MTF. For the most reliable answer, check the owner’s manual or contact a Toyota dealer with your vehicle identification number (VIN) to confirm the exact specification.
