BestLine Power-Train lubricant is the most advanced power-train treatment and is compatible with all other fluids and gear oils. It cleans the valve body and plates, allowing for a quicker and more efficient shift and cooler operation temperature for the automatic transmission. The power-train lube treats gears and bearings with a protective coating that resists wear while allowing for quicker and more efficient operations in standard transmissions/differentials. It enhances the efficiency of the water pump, lubricates the bearings, while coating the radiator with a protective layer to reduce oxidation and improve flow of coolant.
