If I interpret your description correctly, the leak is in the transmission casting. Cracking can happen there if someone unknowingly unbolts the speedometer angle-drive on the right side, behind the halfshafts. Done wrong, this frees up a 4" extension shaft to FALL INSIDE! There's not much extra room in there so driving the car with the shaft loose inside can and has driven that shaft into the case, cracking it & wrecking the little $250 shaft. I've welded up a couple of cases from this. I've also seen other loose metal parts drift around inside and get caught in the gear mesh, with similar results.
Contrary to what Jack says removing the angle drive has no effect on the ZF, just do not take out the 10mm bolt below the speedoemter drive without having something clamped to hold the speedometer drive as that holds the driveshaft in place.
IMO you are throwing the dice if you continue to drive teh car or JB weld the crack. There's potentially a problem and it can only get more expensive the longer you ignore it.
