Most of the aftermarket fluids for these taco's need not be specific. Only the transmission if an auto when doing those drain, and refills I learned the hard way that they should be only toyota brand. These gen3 transfer cases are super fussy if living in a cold climate where they require the toyota transfer case fluid. Red line can also be used, but there's not much else.
Heck, I swear if toyota manufactured tires with their name on them, some would only buy them.
