No "transfer" case in the traditional sense, but a PTO, Power Take Off, case. And yes, it is separately lubed, with fairly heavyweight gear oil, but I doubt if it needs to be serviced EVER. At ~65,000 miles the gear oil in my 2001 AWD RX300 PTO case (includes VC, Viscous Clutch) remained clear and non-odorous. Yes, I said CLEAR. Silicon gear oil..??
And gear oil doesn't STINK unless it has been subjected to extreme HEAT, which is not the normal case.

Oh, man. You should have seen the stuff that I drained out of my Miata. Just 26k miles, too. To be fair, it was 8 years old. It has a viscous limited-slip rear diff, FWIW. It looked like melted chocolate, too, coming out.
