Abstract
Friction modifier additives useful in power transmission compositions, particularly automatic transmission fluids, is disclosed. The additive comprises Component-1 alone formed by condensing a polyamine, such as tetraethylene pentamine, with an aliphatic mono acid, such as isostearic acid, or a mixture, and/or salt, of Component-1 and a Component-2 wherein Component-2 is an acid ester formed by reacting a heterodialkanol such as thiobisethanol and a hydrocarbyl substituted dicarboxylic acid or anhydride, such as octadecenyl succinic anhydride.
