SCOPE The materials defined by this

2、 specification are the basic components for the automatic transmission friction modifier for anti squawk (NVH) phenomenon. 2. APPLICATION These specifications were originally released for shifting clutch NVH issue in automatic transmissions. This material needs to added to WSS-M2C938-A (Type A) ATF

3、in 0.95ml / 1.0 lit ratio for optimized performance. Adding this material will result in reduction of static coefficient of friction by approx. 5-10% (depending on friction material used). This material will not have impact on dynamic coefficient of friction. 3. REQUIREMENTS 3.1 STANDARD REQUIREMENT

4、S FOR PRODUCTION MATERIALS Material suppliers and part producers must conform to the Companys Standard Requirements For Production Materials (WSS-M99P1111-A). 3.2 REQUIREMENTS 3.2.1 Viscosity, cSt at 100 C 3.90 min (ASTM D445) 3.2.2 Density, g/cc at 15 C 0.80 min (ASTM D 1475) 3.2.3 Flash Point 180
