Phillips 66® Triton Heavy Duty ATF is a full-synthetic, heavy-duty automatic transmission fluid designed for use in truck and bus transmissions operating under severe service conditions or in extended drain intervals. It is particularly recommended by Phillips 66 Company for use in applications where the OEM specifies a fluid providing performance capability comparable to the Allison on-highway extended drain specification.
Triton Heavy Duty ATF has excellent shear stability and high load-carrying ability to protect against viscosity breakdown and wear. It has excellent oxidation resistance and thermal stability to minimize the formation of sludge and varnish, and excellent friction durability to ensure smooth shifting and proper transmission performance for the life of the fluid. It also has outstanding low-temperature properties for year-round use and protects against rust and corrosion.
Triton Heavy Duty ATF can provide extended drains up to 4 times the normal interval for a conventional all-mineral automatic transmission fluid. It was field-tested for over 100,000 miles in a fleet of city transit buses operating in severe stop-and-go service. During this test, it provided outstanding protection against wear, glazing and sludge and deposit formation, while maintaining excellent shift quality throughout the duration of the field test.
