Valvoline DT Transmission 10W is a specialized transmission oil formulated for heavy construction and mining equipment that demands high-performance drivetrain lubrication. Produced from high-quality base oils combined with carefully selected additives, this oil is engineered to meet the most rigorous requirements of modern heavy equipment operating in demanding environments.

DT Transmission 10W is specifically designed for use in transmission systems and as a hydraulic fluid in equipment requiring advanced lubricant performance. Its lower viscosity grade provides excellent cold-weather fluidity, ensuring reliable shifting and immediate hydraulic response during startup in cooler operating environments. This makes it particularly well-suited for equipment operating in temperate climates or during seasonal transitions when ambient temperatures vary widely.

The oil delivers outstanding wear protection for heavily loaded gear sets, bearings, and hydraulic components, helping to extend component service life and reduce costly unplanned downtime. Its optimized friction characteristics ensure smooth, consistent wet brake operation — a critical safety factor in heavy equipment applications where precise braking control is essential.

DT Transmission 10W is recommended for transmission systems and wet brakes in Caterpillar heavy trucks, earthmoving equipment, and other machinery where high-performance transmission lubrication is specified. It is equally suitable for any equipment where a lubricant meeting advanced drivetrain performance standards is recommended. This oil is not designed for use as an engine oil. Fleet maintenance operations and equipment managers benefit from its reliable performance, reduced component wear, and ability to extend service intervals under the punishing conditions encountered in construction, quarrying, and mining operations.
