'90 legacy wagon auto trans, 150,000 miles... now hearing a pulsing grinding noise in the auto transmission or differentiial .. differential was out of oil ..no sign of leakage .. refilled with oil ..still makes grinding noise ... noise occurs when driving not idling .. while driving about 30 mph when noise is audible ..put in neutral and noise stops ..but then the noise returns, if you rev up the engine while still in neutral while coasting the noise comes back ...any thoughts??? much appreciated
