The structure of the fluid is determined by the numerous tasks it must fulfill in the operation of an automatic transmission. Along with the classical tribological functions of the fluid such as the lubrication of gears, antifriction bearings, friction bearings, axial plates, one-way clutches and the like, a special problem of tribology exists in automatic transmissions, and that is the influencing of power shifts. The transmission of torque during the slipping of clutches proves to be extraordinarily sensitive to the development of the friction coefficient dependent on the slinding speed. Additives have now been developed to achieve the friction coefficient characteristics necessary for good shifting quality and to maintain them during the full working life of the fluid, even if fluid changes are made at long intervals.
