Fluid type explained

The 2022 Toyota RAV4, depending on the powertrain, utilizes either the Aisin U881F (gasoline models) or the Aisin U880F (hybrid models) automatic transmission. Both transmissions are designed to operate exclusively with Toyota Genuine ATF WS (World Standard) fluid. This fluid is a highly specialized, low-viscosity synthetic formulation engineered to meet the precise demands of these modern transmissions. Using any other fluid, even one marketed as a "multi-vehicle" or "compatible" ATF, can lead to premature wear, shuddering, shifting problems, and ultimately, costly transmission failure.

Toyota Genuine ATF WS is carefully formulated to provide optimal friction characteristics for smooth gear changes, maintain proper lubrication under extreme temperatures and pressures, and protect internal components from wear and corrosion. Its lower viscosity, compared to older ATF types, contributes to improved fuel economy, a key consideration in the RAV4's design.

Service procedure

Unlike older transmissions with easily accessible transmission pans and replaceable filters, the Aisin U881F/U880F in the 2022 RAV4 is designed with a "sealed for life" philosophy, though this term can be misleading. While there isn
