Transmission Drain Plug
I just got under my 1993 4Runner with the 3.0L (auto) to change the oil...and noticed two plugs that where close to each other....one was the transmission drain and i cant figure out what the second plug is for...maybe just a second drain?..correct me if im wrong but the transfercase drain and fill plugs face the rear of the vehicle....and i believe in this application the drain on the transfercase had an allen head in it.

Are they both on the tranny pan?

You are correct the transfer case drain and fill plugs face the rear of the vehicle. I have seen that 2nd tranny oil pan too, but I have never drained it or removed it. On my BMW there is a 2nd small tranny oil pan too that I have dropped and cleaned out. I think it is called a sump pan? There was no pickup tube in it, I guess it is just a little reservoir that collects sludge. On our Toyotas it looks like you would have to remove the cross member to drop that little pan though.

I have a 92 3vz-e and I just drained my sump because I thought it was the transfer case drain plug(which I'm not sure exists) Anyways, does the sump need to be refilled or does it refill from the transmission fluid pan? If not..how is it refilled. I didn't see a refill hole on the sump pan; but maybe I missed it.

The transfer case has drain and fill plugs on the back of the t-case (facing the rear of the truck). Make sure you take the fill plug out before the drain plug just in case you can't get the fill plug out you won't be stuck with no ATF in your transfer case. You fill it until the ATF runs out of the fill plug.
