Automatic Transmission keeps blowing seal between engine &a/tA on 2002 Mitsubishi Montero Sport
I am wondering if there is a vent hose that is plugged causing pressure build up in the transmission. When the transmission was replaced was it new/rebuilt or a wrecking yard transmission (if so were the seals replaced?
It was a used transmission. Seals were new. I had this same problem with previous transmission. I am thinking it maybe the Powertrain Control Module and/or the car computer. Nothing on outside of transmisssion was pluged. I am thinking soomething is telling the transmision to do something it isn't suposed to do at the wrong time. I know for a fact that cell phone transmision has interfered with car ECM'a and also there have been claimed to cause problems with the Powertrain Control Module.But, I have no way to test.

Did you also rreplace the torque converter? The front pump bearing? If not, sounds like your problem.a new seal still leaks if the bearing is worn, allowing the converter to bounce around. You might even have cracks around bolt holes in flywheel..
