So..92 Loyale 3at, going to flush out the tranny, what gear oil weight do I use and tranny fluid. And what weight for the rear diff?

Gear oil i would go 75w-90 non synthetic. For tranny fluid HTKYSA calls for Dextron II. I dont think that Dextron III would hurt anything either however. The parts place you buy the oil at should be able to recommend what to use. I think when i did a flush (ages ago) i used dextron III and it was just fine.

Dexron III is fully backward compatible with the Dexron II spec. It just has some additional additives and smells like moth-balls now.

 

75w90 in the front and rear diff.
