I used Valvoline 75W-90 in a GX460, no issues.
Toyota tends to use Torsen LSDs but clutch-type ones have been used in the Supra and JDM Soarer(SC300/400 here) and offered in the TRD Pro Tundra/Tacoma.
The wildcard Toyota fluid is the transfer case fluid, Transfer Oil LT, a 75W GL-4 oil. Red Line MT-LV works for that.
