AMSOIL Torque-Drive Synthetic Automatic Transmission Fluid (ATD)

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

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.

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.


Use in heavy-duty automatic transmissions in on- and off-highway applications that require any of the following specifications:

  • Allison TES-295, TES-389, TES-668, C-4;
  • Ford MERCON V;
  • Isuzu SCS; JASO 1-A;
  • 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;
  • Volvo 97340, 97341;
  • ZF TE-ML 03D, TE-ML 04D, TE-ML 14A, TE-ML 14B, TE-ML 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.

Best Allison Fluid

By  ALEC,  a  Verified Buyer  from  Upland, CA   on  January 04, 2024
This is not the first time I’ve used Amsoil product. I use all their signature series engine oils and gear oils. I have noticed nothing but quieter operation, better economy, and smoothness. I have now drained all the of GM- Dexron ATF from my Allison 1000 and replaced it with Amsoil Torque Drive. Since switching I have had smoother shifting and better economy on top of cooler temps (but I added a maghytec extended capacity trans pan).

Amazing in my Allison

2013 Chevy Silverado 2500HD Duramax Allison 1000 6 sp. 43,000 miles. 2nd owner. Shifts much smoother, seems quieter, and runs about 10 degrees cooler. Not sure i

Torque Drive

By  THOMAS,  a  Verified Buyer  on  July 23, 2022
I run both my trucks on Amsoil products. I recently purchased a used Duramax to pull my fifth wheel camper. Not knowing recent maintenance intervals, I decided to do a full Amsoil change over. Reading blogs about what fluid to run in an Allison transmission is quite entertaining and controversial. Amsoil has always done me well, so I decided to go with the Torque Drive. My transmission shifts are unnoticeable when not pulling and firm and crisp while pulling my trailer in tow/haul mode. I was really considering having my transmission rebuilt, but now it is working so flawlessly, I’m going to keep running it as is.
