My power steering has an air leak and my transmission is leaking fluid. Clues? on 1998 Mitsubishi Montero Sport

I recently had my alternator replaced and literally the moment it was started and backed up the power steering acted like it had air in the line. Still does, in fact, but now I have a serious problem: my transmission is leaking like a seive, and the leak seems to be in the vicinity of the mounting bolts for the underside of the Alternator. Anybody got any suggestions or clues for me?
