I have a pretty serious trans leak at the passenger rear corner of the trans oil pan. It is dripping from the bolt. I replaced the gasket but the leak is still there! Is it possible the pan is warped, maybe the tab with the bolt hole is bent? Visually it looks fine. Trans works great. I cannot trace the leak from anywhere else. I cleaned the area and it appears that it is in fact leaking at the gasket. Are there any connections/seals above the rear passenger side of the trans that I would not be able to see without dropping it?
