Chevrolet Dealer (Ourisman in Alexandria, VA) specified and sold me AC Delco Dexron VI for my 2004 Duramax with Allison.

I may be wrong as I did not notice it was an Allison 3000 but what I have indicated is true for a 2004 Allison 1000.

Allison ONLY recommends transmission fluid that is TES-295 approved. Several manufacturers meet this spec. I would not use any fluid that does not say that it meets the Allison TES-295 specifications. The older transmissions did come with a non-295 Fluid, probably Dex III in your case, but why go with any inferior fluid when Allison now recommends a fluid that meets TES-295 in their older transmissions. You do not have to buy Allison fluid if you don't want to give them the money but I would definitely recommend buying the newer spec fluid from someone, anyone, instead of using an older fluid. Saving a few bucks on a transmission that can cost $5000+ to repair just doesn't make sense. BP, Castrol, and others make the TES-295 fluid that you need. Try to find one on sale and use the right, most recent fluid, instead of using a fluid that Allison abandoned many years ago for their transmissions.

The Diesel Supplement manual for the 2018 D/A recommends Dexron VI above temps of -40 F. Below that it specifies TES 295. That holds true for 2013 and up model years
So basically anyone that has an Allison transmission anywhere other than the frozen arctic should not use Transynd TES-295 rated fluid, since most of the lower 48 has temps above -40 F. Only use TES-295 for temps less than -40 F. I think you need to reread your source. :B
