AMSOIL Torque-Drive Synthetic Automatic Transmission Fluid


Recommended for use in applications specifying Allison® TES-295 or C4, DEXRON® III, MERCON®, ZF® TE-ML 14C


Engineered to eliminate the deficiencies common to all conventional, petroleum ATF's, AMSOIL Torque-Drive Synthetic ATF 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. Poor quality oils need frequent changes and they reduce the effective service life of transmissions. Delivering the ultimate in oxidation resistance, wear control and friction performance, AMSOIL Torque-Drive extends lubricant life up to six times* and provides protection beyond that possible from conventional ATF's. Vehicles stay on the road longer, unnecessary labor and maintenance costs are reduced, and the return on costly transmission investments is maximized. Immediate financial benefits are realized upon the installation of AMSOIL Torque-Drive.

* Depending on duty cycle, local conditions, oil analysis and/or OEM recommendations.

Thermal and Oxidative Stability

Hot weather and operating conditions are no excuse for poor transmission reliability. By delivering a slower than normal oxidation rate, AMSOIL Torque-Drive prevents sludge that blocks small valves, prevents varnish that restricts component movement and reduces oil thickening that slows down shift times. AMSOIL Torque-Drive lasts longer than conventional ATF's, protects better than conventional ATF's and extends transmission life beyond that possible with conventional ATF's.

Shear Stable

Conventional automatic transmission fluids use petroleum oils with viscosity index (VI) improvers added to increase the oil's operational temperature range. Over time, VI improvers shear down, promoting premature wear by leaving only a thin base oil to protect vital transmission components. AMSOIL Torque-Drive does not contain VI improvers, which means no VI shear down regardless of the operating environment. The unmatched film strength of AMSOIL Torque-Drive prevents wear, significantly increasing the transmission service life.

Friction Durability

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 assures consistent, smooth clutch engagement with no harsh shifting throughout the life of the fluid. AMSOIL Torque-Drive maintains proper coefficients of friction, prevents clutch glazing and prevents elongated shift times.

Extreme Temperature Performance

Transmissions operate in temperature extremes. In hot temperatures, the synthetic construction of AMSOIL Torque-Drive virtually eliminates oil evaporation and delivers a better lubricating film than conventional oils for better overall protection of vital components. Oil consumption is reduced and transmissions require less maintenance.

In cold temperatures, AMSOIL Torque-Drive easily flows, as it does not contain the wax found in conventional ATF's. Cold temperature fluidity allows for the proper operation of small, delicate, electronically controlled solenoids that affect gear changes. Unlike conventional ATF's, transmissions using AMSOIL Torque-Drive have quick response times during cold operations and can be used immediately upon start-up.

Product Applications

AMSOIL Torque-Drive is recommended as a direct replacement for Allison® or Castrol® TranSynd® Synthetic ATF in heavy duty, on and off highway automatic transmissions manufactured by Allison®, General Motors®, Voith® and Ford® or wherever the standards TES-295, C-4, Dexron® III or Mercon® are specified. Examples of operations that benefit from using AMSOIL Torque-Drive include municipal or transit buses, garbage haulers, motor homes, delivery vans, emergency vehicles, school buses, dump trucks, utility vehicles, cement trucks, line haul trucks and tow trucks.

Where extended drain intervals are not specified by the original equipment manufacturer (OEM), it is recommended that AMSOIL Torque-Drive be evaluated with oil analysis at standard OEM drain intervals or more frequently to establish proper drain interval. Where extended drain intervals are recommended by the OEM, follow that recommendation. This includes the recommendations set by Allison® in document #10-TR-99 Rev. B, January 2002, for TES-295 quality fluids.

AMSOIL Torque-Drive™ Synthetic Automatic Transmission Fluid is based on the same type of chemistry as TransSynd®. This fine, infra-red scan (IR), revealing a chemical "picture" of both products, shows no measurable differences.
