My 4spd manual box leaks oil after an hour or so of fast(for an 82)
driving. The trans. oil drips out between the engine and gearbox. This only
started after I drained and refilled the gearbox a few months back and
noticed that I put more in than came out. I presume the problem is the a
gearbox input shaft seal. Any experience with this gremlin would be most
welcome.
