The need to EXCEED THE NEED with ATF

[Gary Allan]

Okay ..while surfing Mobil's site I came across D1 AFT

Specifications & Approvals

Mobil Delvac Synthetic ATF has the following builder approvals:
Allison TES-295 (AN - 051005) X
Allison C-4 (CN - 31092005) X


Typical Properties

Filling
RH000076
Mobil Delvac Synthetic ATF
Viscosity, ASTM D 445
cSt @ 40º C 39
cSt @ 100º C 7.3

Now it meets the Allison TES-295 spec.

So I say, what does that mean to me

..so I put ATF TES-295 into google and, naturally, every Amsoil site in the known universe popped out.

Product Applications
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.

So the question is, Since Amsoil Torgue-Drive is a Dex III fluid that meets Allison TES-295 ...does all TES-295 fliud meet Dex III specs????

Actually, Amsoil Torque-Drive does NOT meet TES-295, and Amsoil states that on their website. This is just another Amsoil product that is "recommended for" a certain application but has not been tested against the spec for which they are recommending it.

All TES-295 fluids meet the generic Dexron III spec, but not vice versa....

Allison Transmission Co. offers an extended warranty on their larger transmissions if a TES-295 certified fluid is used. The main brand is Castrol Transynd. BP/Castrol, ExxonMobil, Cognis, and International Trucks are the only brands which have the TES-295 approval.

Amsoil was the first to duplicate the Transynd ATF, but as usual does not want to be part of Allison's scheme. It has, however, been tested.

Pablo, Amsoil states plainly on their website that this ATF has not been put through the battery of tests necessary to get TES-295 approval. Whatever "testing" Amsoil does in-house is irrelevant, IMO.

 

[TooSlick]

Amsoil has cleverly "reverse engineered" the Castrol Syntrans fluid, so that even a complete, spectrographic trace can't tell them apart. The additive packages are also exactly the same, as is the 4.0 Cst, PAO basestock.

So there is no need to test it, since it's the same chemical fluid....If you switched the containers, even Castrols lab couldn't tell these fluids apart.

Good Question and I see what you're driving to.

My belief is that a TES-295 fluid will meet up to
DexIII(G) specs. I am not convinced it would meet DexIII(H) fluid specs.
