The hose connects to the top of the transmission, underneath the car's battery (you'll have to remove the battery to see the connection site). It's important that this hose, once reconnected, does not does not get crimped. If the hose is not free to "breathe" pressure buildup in the transmission can cause fluid to pour out of the fill point (where the dip-stick goes).
