    • An automatic transmission fluid composition is provided to improve friction characteristic, thermal stability, oxidation stability, and shiftability and to secure a wide temperature application range. The automatic transmission fluid composition contains high pure oil of 65~80wt.% produced by three hydrogen treatment processes, polymethacrylate of 2~10wt.%, a friction modifier of 2~5wt.%, and an additive of 10~20wt.%. The viscosity index of the high pure oil is 122~126 and the high pure oil contains saturated hydrocarbon over 99% and sulfur below 1ppm. The friction modifier consists of non-boron succinate imide of 40~60wt.%, dialkyl hydrogen phosphite of 5~15wt.%, and a diluent of 25~45wt.%. The additive consists of boron succinate imide of 10~20wt.%, condensate of fatty acid and amine of 3~10wt.%, an anti-oxidant, an antifoaming agent, and the diluent.
