altima transmission drain plug

[schyawn]

Ok guys/girls, I feel ridiculous here. I've done transmission oil changes on my old 240, no problems. I have a 93 altima and I cannot find the drain plug on the manual transmission. I can find the fill plug easily. I looked it over and there is no other square-ratchet-hole plug on the bottom of the transmission, only on the side for filling. How the heck do you drain the oil? Please help this idiot.

Thanks, sean.
