AMSOIL Torque-Drive Synthetic Automatic Transmission Fluid (ATD)

Recommended for use in applications specifying
Allison® TES 295 or C-4

Allison transmission fluid Torque DriveEngineered 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.

Wear Protection

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.

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 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.


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.


AMSOIL recommends Torque-Drive for use in heavy-duty, on-and off-highway automatic transmissions requiring any of the following specifications: Allison TES-295, TES-389, C-4; Ford MERCON V; GM DEXRON III-H; Isuzu SCS; MAN 339 Type V-1, 339 Type V-2, 339 Type Z-1, 339 Type Z-2, 339 Type Z-3, 339F; MB 236.91, 236.10; Voith 55.6335, 55.6336; Volvo97340, 97341; ZF TE-ML 03D, TE-ML 04D, TE-ML 14A, TE-ML 14B, TEML 14C, TE-ML 17C, TE-ML 20B, TE-ML 20C.

Examples of operations that benefit from using AMSOIL Torque-Drive include municipal or transit buses, motor coaches, garbage haulers, motor homes, delivery vans, emergency vehicles, school buses, dump trucks, utility vehicles, cement trucks, line haul trucks, tow trucks and more.


Torque-Drive is recommended for use according to the extended service interval established by the original equipment manufacturer for the performance specifications identified above under Product Applications.

Allison® transmission has established the Technical Engineering Specification 295 (TES 295) for automatic transmission fluids. When TES 295 products are used in Allison® transmissions and according to Allison® recommendations as outlined in Allison® Service Information Letter 10-TR-99, Rev. B, the service life of these oils can be extended several times that of mineral oils. This extended drain recommendation saves money for Allison® transmission owners.

Non Heavy-Duty vehicles (Passenger cars and light duty trucks):

Please use the vehicle product look-up guide to verify this is still the best product for your specification. The AMSOIL ATF products have been upgraded several times since Torque Drive came. In many instances the ATF exceeds the performance so you can verify the proper fluid here in the AMSOIL Vehicle Product Look-up Guide.


In response, AMSOIL closely examined TranSynd® and developed a cost-effective replacement product named Torque-Drive™. Torque-Drive™ is a premium synthetic transmission fluid based on the same type of chemistry as TranSynd®. This is supported by the infrared (IR) scan and physical data comparisons included here. Clearly, the testing shows no measurable performance differences between Torque-Drive™ and TranSynd®.

The Allison® extended warranty states that Allison® will only cover repairs in which the transmission had been operated with TranSynd® or an equivalent fluid which meets the TES 295 specification. Torque-Drive™ is, in fact, based on the same type of chemistry as TranSynd® and is, therefore, recommended by AMSOIL as a replacement for TranSynd® and for use in all TES 295 applications. And because it is not specifically designated by Allison® as a TES 295 product, the AMSOIL warranty is in place to cover all lubricant related failures.

All Allison® transmission owners would be wise to reevaluate their use of TranSynd®, as well as their investment in the Allison® extended warranty program.

The AMSOIL and Castrol products are so exact, it cannot be determined if the AMSOIL product is used. It's an exact copy for less money.

Product Applications
AMSOIL Torque-Drive™ is recommended as a direct replacement for TranSynd® Synthetic ATF in heavy duty, on and off highway automatic transmissions manufactured by Allison®, General Motors®, Ford®, Voith® and ZF® or wherever the standards TES-295, C-4, Dexron® III, Mercon® or TE-ML 14C 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 fluids.
