TRITON® 668 ATF
ALLISON TES- 668 APPROVED PREMIUM SYNTHETIC, HEAVY-DUTY, AUTOMATIC TRANSMISSION FLUID
Phillips 66® Triton 668 ATF is a full-synthetic heavy duty automatic transmission fluid designed for truck and bus transmissions operating under severe conditions or in extended drain intervals. Triton 668 ATF is designed for use where the OEM specifies a fully approved Allison TES-668 fluid.
Triton 668 ATF offers excellent shear stability and high load-carrying ability, safeguarding against viscosity breakdown and wear. It provides superior oxidation resistance and thermal stability to minimize sludge and varnish formation. Its excellent friction durability ensures smooth shifting and optimal transmission performance throughout the fluid's lifespan. With outstanding low-temperature properties, Triton 668 ATF is suitable for year-round use and protects against rust and corrosion.
