Looks like Allison has released a new fluid. I just called my local Allison dealer to pick up a box of 6 gallon jugs of TES-295 TranSynd and I learned that they are in the process of changing over part numbers to the new TES-668 TranSynd. It is fully backwards compatible with TES-295. Not really sure of the other specifics.
