Torque Drive® (ATD)

Amsoil Torque-Drive® Synthetic Automatic Transmission Fluid (ATD)

Data Bulletin 

Product Highlights

Engineered for outstanding performance in heavy-duty transmissions manufactured by Allison, Voith, ZF and other heavy-duty transmissions. Excellent protection in temperature extremes. Ensures consistent, smooth clutch engagement over the life of the fluid and controls clutch glazing and elongated shift times.

Engineered to eliminate deficiencies common to conventional petroleum ATFs, Amsoil Torque-Drive provides superior performance and protection against thermal and oxidative degradation, sludge and varnish formation, viscosity shear down, cold-temperature oil thickening, poor friction stability, high component wear and shortened oil life. Automatic transmission operating expenses can be directly linked to transmission fluid quality. Immediate financial benefits are possible upon the installation of Amsoil Torque-Drive. Vehicles stay on the road longer, unnecessary labor and maintenance costs are reduced, and the return on costly transmission investments is maximized. Amsoil Torque-Drive is a multi-functional fluid ideal for mixed fleets of vehicles, meeting the most stringent heavy-duty transmission specifications and helping eliminate compatibility concerns and misapplication.

Protects Against Wear

Transmissions operating under severe-service conditions can cause transmission fluid to break down and allow damaging metal-to-metal contact and increased wear. Amsoil Torque-Drive is formulated to exceed industry requirements. Its top-of-the-line synthetic base oils and premium additives deliver superior viscosity retention and high film strength to help prevent wear and reduce operating temperatures during severe-service operating conditions.

Durability Under Heavy Friction

Oxidation by-products destroy the sensitive friction characteristics of transmission fluids, resulting in the rapid degradation of shift quality. The thermal and oxidative stability inherent in Amsoil Torque-Drive helps ensure consistent, smooth clutch engagement in heavy-duty applications throughout the life of the fluid. Amsoil Torque-Drive maintains proper coefficients of friction, and helps prevent clutch glazing and elongated shift times.

Performance in Extreme Temperatures

Hot operating conditions are no excuse for poor transmission reliability. By delivering a slower-than-normal oxidation rate, Amsoil Torque-Drive helps prevent sludge that blocks small valves and varnish that restricts component movement, and reduces oil thickening that slows shift times.

In cold temperatures, Amsoil Torque-Drive easily flows, as it does not contain the wax found in conventional ATFs. Cold-temperature fluidity allows for the proper operation of small, delicate, electronically controlled solenoids that affect gear changes. Transmissions using Amsoil Torque-Drive have quick response times during cold operation and can be used immediately upon startup.
