I've got a leaky hydraulic clutch line. It's not the master cylinder and it's not the slave cylinder, both of these areas are dry. It has lost over half the reservior in the last 3 weeks and looks like the fluid is leaking out of some kind of hydraulic junction box mounted on top of the transmission. Has anyone seen this before or know what's going on?

I just cleaned up the area so it should be easier to watch what's going on. Might be the rubber line from that box to the slave cylinder.
