AMSOIL Torque-Drive Synthetic Automatic Transmission
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 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.
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
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.
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.
Synthetic Automatic Transmission Fluid is based
on the same type of chemistry as TransSynd®.

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 prices.
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 indefinitely.
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 Allison.
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 ATF's.
