DAUER ATF F4 automatic transmission fluid is 100% synthetic and formulated to be used in all those transmissions where ATF + 4 is recommended. This new formula provides oxidation stability and foam resistance, in addition, to prevent a loss of viscosity. It can be used in all-new generations of CHRYSLER and older transmissions when the use of ATF +, ATF +2, and ATF +3 is recommended. This new formula allows you to extend the periods of change of this fluid in your vehicle.
