I said Amsoil nor Royal Purple are on the ALLISON approved list. Allison is no longer part of GM. They are also not TES-295 but TES-389. That being said, Amsoil and Royal Purple, IMO, should do very well as a synthetic in any transmission.
AMZ/OIL does make a trans fluid for the Allison.
The Universal ATF is for most auto trans.
