ABSTRACT:
The friction performance of a lubricating oil composition that has been compounded to serve as a functional fluid that is particularly useful in mechanical and hydraulic units containing wet clutches, for example an automotive automatic transmission, is greatly improved by the incorporation of a combination of a friction modifier of the type comprising a straight chain alkenyl or alkyl C.sub.4 to C.sub.10 dicarboxylic acid or the reaction product of an aldehyde/tris hydroxymethyl aminomethane adduct and a long chain dicarboxylic acid anhydride such as an alpha-olefin succinic anhydride; with an overbased detergent salt such as an alkali metal salt or alkaline earth metal salt of a hydrocarbyl sulfonic acid, an alkyl phenol or a sulfurized alkyl phenol, in certain proportions.
