ATF PRO TYPE J1 is an automatic transmission fluid which is made from high quality semi-synthetic base oils providing improved viscosity index. Viscosity in low temperature is very low so that it assures good starting performance and less power loss due to viscous resistance in such cold-start condition. On the other hand, ATF PRO TYPE J1 keeps good shear stability and oxidation stability, and offers long-life effective protection of AT mechanisms at a wide range of temperatures.
It is compatible with “slip control lockup AT” which is the mainstream of JDM AT vehicles. It prevents judder from slip control of a lock-up clutch in the low speed operation, by the long-life, excellent wet clutch friction characteristics. Furthermore, it secures a high torque transfer capacity for high power vehicles. It offers quick gear change, superb acceleration response, less of shift shock and less judder vibration. You will feel stable power transfer and smooth and quick gear operation.
GReddy ATF PRO TYPE J1 fulfills 1A03 ATF Specification by JASO: Japan Automotive Standards Organization and Dexron III H-equivalent specification. The high performance ATF matches almost all JDM AT vehicles.
