i just helped replace a tranny in a burban a couple of weeks ago.. now its back with a bad tranny.. on the left rear side, on the back of it that round thing that has the metal flip thing holding it on, forget the nameof it. it has been pushed out enough that you can see the rubber oring behind it, and where it would normaly be seated at... look at that while you are under it...
