TOYOTA GENUINE ATF WS
Toyota Genuine ATF WS is used to reduce the resistance of the ATF and improve the fuel economy by reducing its viscosity in the practical operating temperature range. At higher ATF temperatures, the viscosity is the same as that of Toyota Genuine ATF type T-IV, which ensures the durability of the automatic transmission.
There is no interchangeability between Toyota Genuine ATF WS and other types of ATF.
