TES-295 fluids go through a rigorous and complete testing and approval cycle by Allison; we can all agree upon that. The "need" for TES-295 fluids is debateable. TES-295 fluids are "required" if you're in an extended service contract with Allison. Use of a TES-295 licensed fluid is a requirement to meet the contract obligations.
Short of that, there are other products that offer the performance of TES-295 fluids, but without the added cost associated with the licensing. TorqueDrive, 204S-AT, and AutoTrans-5 all come to mind. For most people that want great performance, but don't "need" to fulfill the "requirement" of a licensed TES-295 fluid, the clones work well and offer a large fiscal savings.
Sure, the clones are not licensed, but that doesn't mean they are inferior; they are just not licensed. Amsoil engine oils are not licensed by the API as far as I know, but their products do very well when used as directed. Licensing is a good thing when you need to be able to prove something under contract. But if not, it's an added expense you can avoid and still get similar, if not the same, performance.
To the OP, Chromer, you have a choice to make. Do you "need" TES-295 fluids, or do you just "want" them? You have some good choices for both licensed and non-licensed fluids. As far as availability, I think you'll find better selection with the clones; TorqueDrive, 204S-AT, are available from supporting vendors here at BITOG. They can be shipped to your door, and for a very fair price.
(BTW - are you the same Chromer from over at DP? Welcome! to BITOG! Assuming this product is for your Dmax/Allison combo, I would suggest the clones over the licensed fluids. Great performance, better price.)
