2006 Toyota Hilux Surf – Transmission Fluid

Transmission fluid is absolutely relevant to the 2006 Toyota Hilux Surf. Toyota’s factory literature for the N210-series Hilux Surf/4Runner confirms its automatic transmissions use ATF: the 5‑speed A750F specifies Toyota ATF WS (World Standard), and the earlier 4‑speed A340F specifies Toyota ATF Type T‑IV. This is documented across Toyota Owner’s Manuals, the Toyota Repair Manual for A750F/A340F units, and Toyota service bulletins introducing ATF WS for sealed automatics. In short, the Hilux Surf is designed to run on specific transmission fluid, and the fluid choice matters.

In this model, transmission fluid does far more than just lubrication. It acts as a hydraulic medium to apply clutches and bands, cools internal components, carries away wear debris to the filter, and manages friction for smooth, consistent shifts. That’s why Toyota matches the fluid to the gearbox design: WS for the A750F’s tighter tolerances and shift strategy
