When I was using TransSynd, I was told that it is made by Castrol. I have the spec sheet around somewhere, ... good stuff.

Valvoline Dex III in 722.3, change every 30k and Shell ATF134 in 722.6, change every 40k....easy and inexpensive. Doesn't need anything else.

Yes - it was blended by Castrol - Im sorry to have worded it wrong, the spec was defined by Allison Transmission.

Its the absolute pinnacle of Dexron III type ATF - even after the brutal dungeon torture it sustains in those allison units - it still remains in serviceable condition for quite a long time.
