What type of gear oil does a Toyota Tacoma take?
The correct fluid depends on which component you’re servicing. For manual transmissions, you typically need 75W-90 GL-4 gear oil; for automatics, you’ll use Toyota ATF WS; and the transfer case usually requires 75W-90 GL-4. Always verify the exact specification in your year’s owner’s manual.
Overview of Tacoma transmission fluids
Toyota Tacomas offer both manual and automatic transmissions, and most 4WD models also have a transfer case. Each component has its own recommended fluid, and using the wrong type can lead to gear wear, shifting issues, or damage over time. Here’s a breakdown by system.
Manual transmissions (5- and 6-speed)
The manual gearbox in many Tacomas uses a conventional gear oil rather than automatic transmission fluid. The typical specification is SAE 75W-90 gear oil meeting API GL-4, which helps protect synchronizers and gears under load.
- SAE 75W-90 gear oil that meets API GL-4 specification (synthetic or high-quality mineral oil).
- Avoid gear oils labeled GL-5, as they may contain additives that could harm synchronizers.
Conclusion: For manual transmissions, aim for 75W-90 GL-4 gear oil. Always confirm your exact year/model in the owner’s manual, as specific variants can exist.
Automatic transmissions (A/T)
Automatic transmissions in Tacomas use dedicated automatic transmission fluid rather than gear oil. The current Toyota specification is ATF WS (World Standard). Use an ATF that explicitly lists WS compatibility, and avoid mixing with fluids not rated for WS unless the manual permits it.
- Toyota ATF WS (World Standard) or an equivalent WS-rated ATF.
- Do not substitute Dexron VI or Mercon fluids unless your manual specifically allows it.
Conclusion: If your Tacoma has an automatic transmission, use Toyota ATF WS or another WS-rated ATF as specified by Toyota for your year.
Transfer case fluid (4WD)
The transfer case fluid for 4WD Tacomas is a gear oil, not ATF, and the most common specification is SAE 75W-90 GL-4. Some years may have different requirements, so the exact spec should be confirmed in the service manual for your specific model and year.
- SAE 75W-90 gear oil meeting API GL-4 for the transfer case.
- Follow the manual’s guidance if it specifies a different viscosity or additive package.
Conclusion: Transfer case fluid is typically 75W-90 GL-4 gear oil, not ATF. Check the manual for your exact year and configuration.
Why the right fluid matters
Using the wrong fluid can accelerate wear, degrade shifting performance, or cause transmission or transfer-case damage. Toyota designs each component to work with a specific viscosity and additive package, so sticking to the recommended spec protects longevity and reliability.
Where to find the exact specification for your Tacoma
Your safest source is the owner’s manual or a Toyota dealership service bulletin. Toyota’s official support site and certified service databases also list the precise fluid specifications by model year and drivetrain configuration.
Summary
In short, manual Tacomas typically require SAE 75W-90 GL-4 gear oil, automatics require Toyota ATF WS, and the transfer case generally takes 75W-90 GL-4 gear oil. Always verify the exact specification for your year and model in the owner’s manual or with a Toyota service professional to ensure optimal performance and drivetrain longevity.
