  A mutually compatible combination of additives and their use to impart anti-wear, dispersancy and friction modification to power transmission compositions, particularly automatic transmission fluids, is disclosed. The additives comprise organic phosphite ester such as dioleyl monohydrogenphosphite; hydroxyl amine compound, such N-octadecyl diethanol­amine, N-octadecyloxypropyldiethanol amine, or N-­octadecylthiopropyl diethanolmine, and dispersant such as that derived by reacting a polyisobutenyl succin­imide with a phosphosulfurized terpene, either alone or in combination with a borated, aminated dispersant such as that derived by reacting a polyisobutenyl succin­imide with boric acid.
