Since it is shifting god--there are no mechanical problems. The rear seal can be easily replaced without pulling the tranny, as can the side o-rings on the accumulators. Front seal requires pulling it.

Why not try using some 'stop leak' that swells the seals and see what happens. Often that will cure the leaks for a good while. Only the front seal is a pain to replace the others easy and cheap. This tranny is not normally a leaker.
