Bought a jug of this and then got cold feet about using it, so I got a VOA. I found some threads on here about Triax engine oil, but none about gear oil. I intended to use it in a ZF S5-42 manual transmission. Ford says to use DexMerc, while ZF says a lot of things, one of which is 75W-80. I see that it has no boron; are the calcium and phosphorus adequate substitutes?
