An power transmission fluid comprising a mixture of a major amount of a lubricating oil and an effective amount of a performance enhancing additive combination comprising: (a) at least one organic phosphate having the structure: R1- X2-P(:X1)(R2X3)-X-R5 where R1, R2, R3, and R4 may independently be substitut ed or unsubstituted alkyl, aryl, alkylaryl or cycloalkyl having 1 to 24 carbon ato ms and X, X1, X2 and X3 may independently be sulfur or oxygen. R1, R2, R3, and R4 may also contain substituent hetero atoms, in addition to carbon and hydrogen, such a s chlorine, sulfur, oxygen or nitrogen; wherein R5 is derived from a reactive olefin and can be either CH2-CHR-C(:O)O-R6; -CH2-CR7HR8; or R9-OC(:O)CH2-CH-C(:O)O-R10 where R is H or the same as R1 through R4, R6, R7, R9 and R10 are the same a s R1 through R4, and R8 is a phenyl or alkyl or alkenyl substituted phenyl moiety , the moiety having from 6 to 30 carbon atoms, (b) a calcium detergent, and (c) a friction modifier.
