Why not go to the experts? Allison has a website where you can enter your transmission information and the EXPERTS can tell you exactly what fluid is best for your transmission. Allison transmissions
Allison recommends several different transmission fluids, made by numerous manufacturers, that all meet their various standards for TES468, TES389, and TES295.
I don't believe that any of the standards specify engine oil or any of the Amsoil products. Perhaps the engineers at Allison know best what works in their transmission and they do not recommend fluids based on advertising and claims by others.
Allison's website currently lists several engine oils for their off-road heavy duty transmissions as approved fluids (Rotella T6, Safety Kleen EcoPower etc.) Currently there are no engine oils listed as approved fluids for on-road applications.
Back in the day when the OP's unit was produced, Allison very likely could have had some engine oils as approved fluids.
The OP should talk to Allison about where to go now. They do answer the phone and are very helpful.
