Where do you add transmission fluid to a 1992 300ZX?

Pour the transmission fluid down the hole the transmission dip stick goes in. You will need a funnel to do it right. WRONG! Do not pour transmission oil into your engine oil compartment! There is no dipstick for transmission oil, at least not on the manual transmission. To fill the transmission, you must pump or pour fluid into the fill hole on the side of the transmission until it dribbles back out.
