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
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
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 Allison.
What are the key performance benefits offered by
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.
