Automatic Transmission Fluid (ATF)
Motor vehicles are equipped with manual, automatic, distribution and axel drives. To ensure proper function of the transmission over the entire period of use, it requires special gear oils for the corresponding modules. Therefore, gear oils are today a structural element in the development. ATF (automatic transmission fluid) are special lubricants with high requirements for use in automatic transmissions. In particular, good viscosity / temperature behavior, high oxidation and shear stability, excellent foaming properties and air delivery capacity, extreme pressure properties and a defined friction behavior are necessary. In addition to special base oils, ATF oils consist of a variety of additives to fulfil all requirements. To avoid confusion with engine oils, automatic transmission fluids are colored red.
