Engineered to eliminate the deficiencies common to all 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.
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 ATFs. 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 ATFs, protects better than conventional ATFs and extends transmission life beyond that
possible with conventional ATFs.
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 improver shear down regardless of the operating environment. The unmatched film strength of
AMSOIL Torque-Drive™ prevents wear, significantly increasing the transmission service life.
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
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. Unlike conventional ATFs, transmissions using AMSOIL
Torque-Drive™ have quick response times during cold operations and can be used immediately upon start-up.
|AMSOIL Torque-Drive™ Synthetic Automatic Transmission Fluid is based on
the same type of chemistry as TransSynd®. This fine Infra-red (IR) scan, revealing a chemical
"picture" of both products, shows no measurable differences.
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, TES-389, C-4, Dexron® III, Mercon,® Voith G-1363 or ZF® TE-ML 14C are specified. 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 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 #1099F for TES-295 fluids.
AMSOIL Torque-Drive™ Q&A
Allison transmission company manufacturers heavy-duty transmissions and recommends maintenance
practices for those units. Allison establishes transmission fluid quality levels through fluid specifications such
as the popular C-4. Allison established another specification for high quality oils called Technical Engineering
Specification-295 (TES-295). Operators using TES-295 oils can extend drain intervals according to Allison
recommendations in bulletin 1099C, and operators are eligible to purchase the Extended Transmission Coverage (ETC)
warranty. ETC is an additional warranty beyond the standard Allison warranty.
What is TranSynd®?
TranSynd® is the only TES-295 licensed synthetic transmission fluid formula available. It is manufactured by
Castrol® and marketed in conjunction with Allison. This formulation is also being made available through other
marketers under private label as well.
Why are there not other products licensed as TES-295?
Competing lubricant companies seeking TES-295 approval for their own formulations are faced with formidable
obstacles. Allison requires a test to be run on a specialized test stand, which it has not made available to other
lubricant companies. Furthermore, Allison requires a field trial but has not established formalized field trial
protocol. This effectively locks out competing oil companies and allows Allison and Castrol to charge exorbitant
How can AMSOIL claim Torque-Drive™ as TES-295 quality without having run the tests?
Because Allison did run the tests on TranSynd® and AMSOIL successfully "reverse engineered" TranSynd®, creating a
fluid based on the same type chemical technology. Both contain PAO. Both contain ester. Both contain enhanced
additive systems. Neither contains VI improvers. Not even sophisticated laboratory analysis can accurately measure
the differences between these two products. The only difference customers will notice is the price. Torque-Drive™
at commercial pricing is considerably lower than TranSynd®.
How will the use of Torque-Drive™ affect the warranty coverage?
The use of Torque-Drive™ will not affect the standard Allison warranty for defects in material or workmanship and
may only be challenged if there is clear evidence of a lubricant related failure, in which case AMSOIL provides
full warranty coverage. Torque-Drive™ does not fulfill the Allison warranty requirements for those customers who
have already purchased ETC. This is a separate contract that binds the parties according to its terms.
Customers who are considering purchasing ETC should give this careful consideration. ETC can be
very costly ranging from $235 per unit for one year in school busses equipped with a 1000 model transmission to as
much as $4,000 per unit for three years in transit busses equipped with a B500R. Allison customers need to ask
themselves where the savings are if they have to pay big dollars for additional warranty coverage which forces them
to use the most expensive transmission fluid available. If Allison customers consider Torque-Drive™ as an
alternative, they will find that the standard Allison warranty for defects in material and workmanship is not
compromised and AMSOIL provides additional warranty coverage for lubricant related failures
How does Torque-Drive™ compare to AMSOIL Synthetic Transmission Fluid (ATF)?
Torque-Drive™ was created to satisfy the concerns of customers currently using TranSynd®, and it carries with it
the confidence to be used for the intervals established by Allison. AMSOIL ATF is a more advanced product with
universal applications such as Mercon V and ATF +4. AMSOIL does not recommend draining or switching to
Torque-Drive™ unless the Allison customer intends on following the extended drain interval recommendations of
What are the key performance benefits offered by Torque-Drive™?
AMSOIL Torque-Drive™ provides superior performance and protection against thermal and oxidative degradation, sludge
and varnish formation, viscosity shear down, cold temperature thickening, poor friction stability, high component
wear and shortened oil life. Conventional oils require frequent changes and reduce the effective service life of
transmissions. AMSOIL Torque-Drive™ extends lubricant life and provides protection superior to conventional
