Fluid Type Explained
The 2023 Toyota Tacoma, equipped with the AC60E (2WD) or AC60F (4WD) automatic transmission, requires Toyota WS (World Standard) Automatic Transmission Fluid. It is crucial to use only genuine Toyota WS fluid or an aftermarket fluid that explicitly states it meets or exceeds the Toyota WS specification. Using an incorrect fluid can lead to premature wear, poor shift quality, overheating, and ultimately, transmission failure. Toyota WS fluid is a low-viscosity, synthetic blend formula designed for optimal performance and fuel efficiency in modern Toyota transmissions.
Never substitute Toyota WS fluid with older Toyota ATF types (like Type T-IV) or universal multi-vehicle fluids unless they are specifically certified for Toyota WS applications. The AC60 series transmissions are precisely engineered, and their internal components and clutch materials rely on the specific frictional properties and viscosity of Toyota WS fluid.
