Amsoil "Torque Drive" (Allison "TransSynd")

[badasp]

Tempest,

Mayby I can help with where to use ATD and ATF. ATD is designed to be used in heavy-duty Allison transmissions. A couple of their requirements are that the fluid is full Synthetic, does not have a viscosity modifier and also meets the viscosity requirements. After making this fluid it was determined that it could also be recommended for similar specifications such as the long drain synthetic requirements for Voith and ZF. The formulation and viscosity also allow us to recommend it for Mercon and Dexron III. It is not meant to be and cannot be recommended for the many specifications that our ATF was designed to be used for. Although our ATF could be used in these heavy duty applications and provide good performance, ATD was designed specifically for those heavy duty applicatons and at a cost much less than the Castrol TranSynd. After Field testing in B500 Allison transmissions AMSOIL ATD and Castrol TranSynd had vertually the same viscosity as the start of the test and if you didn't know which sample was which, you could not tell any difference by the wear PPM's.

For a full listing of what specifications we recommend ATF and ATD for visit our web site.

I hope I've added some information that helps everyone understand.

It ought to be made clear, though, that even though Amsoil ATD is marketed for use in Allison transmissions where TranSynd is reccomended, it does not meet Allison's TES-295 spec.

But I reckon that should be no surprise.

I am interested in using the ATD in my 2007 Civic LX. Amsoil Universal ATF has a viscosity of 6.8 @ 100°C, whereas ATD has a viscosity of 7.41 @ 100°C. This leads me to believe that the ATD will provide better protection than the Universal ATF, but I may not be seeing the big picture. Pablo should be able to clear this up. I wonder why Amsoil opted not to sell ATD in quart bottles?

Here's another point of view. Dexron-VI has a lower starting viscosity than III(H), but offers better wear protection and higher film thickness. You can draw your own conclusions.

Be careful what you read from The Critic. Of course he is correct, but he leaves out certain details. I'm not sure yet why he does this.

Absolutely Dex VI has "a lower starting viscosity than III(H), but offers better wear protection and higher film thickness." Why would anyone think it doesn't? Again he is talking about a generically formulated petroleum based, non specialized conventional Dex III. I did not notice this was related to the topic at hand.

He was considering ATD as he thought the higher starting viscosity would provide him with better wear protection than the ATF. I was trying to tell him that a higher starting viscosity may not necessarily equal better wear protection.

But you didn't state it in that manner.

Of course you were. So why didn't you say that?
