Phillips 66® Triton® Synthetic MTF is a premium, full-synthetic manual transmission fluid specifically engineered for use in heavy-duty manual transmissions that require a non-EP (Extreme Pressure) lubricant. This advanced formulation is tailored for modern gearboxes that utilize synchronized gears, providing the precise frictional characteristics necessary for smooth, "no-clash" gear engagement. By utilizing a 100% synthetic base stock, Triton MTF delivers exceptional thermal stability and shear resistance, making it the ideal choice for vocational trucks and commercial fleets operating in the variable climates of the Pacific Northwest. It ensures that internal components remain clean and protected from wear, even under the high-torque demands of severe-duty hauling.
