It never leaked. I dropped the pan to change the ATF. Leaked. Did it again, two different times. Straightened flange (looked ok), rubber gasket, cork gasket. I just replaced the pan with a new B&M deep pan. SAME THING!!!!!
I've never seen this before. How can I seal this thing?
 
are you sure its the pan? if so I use the cork gasket spray it with copper coat and put it on with a nut driver.
 
I'm sure it's the pan. (famous last words...)
It's a Turbohydro 400 in my Chevy-chassis step van, that I use for my business. Being in a step van, it gives me plenty of room to see. I've cleaned everything several times in order to see the leak. Above the pan stays dry.
I always use white grease on gaskets, it has always worked nicely- helps the seal and makes them easy to remove. Copper coat's a good idea. I might even have some.
 
was going to say to go to the dodge dealer and get one of the new rubber o-ringed gaskets.........but
 
I should've mentioned it's not a Mopar trans in my first post. "Full disclosure". I just figured a pan is a pan.
Today, I took a closer look. I looked at possiblities other than the pan before, but I was thinking pan because it didn't leak before I dropped it. Today's closer look revealed that the passing gear connector (passes through the case, and is sealed by an o-ring), was leaking, running along the pan and dripping off at the rear!
You guys made me think, that's why I posted.
"Famous last words". :-\":-\"
 
..............U cant use grease......it softens the gasket too much allowing it to crush too much and possibly split.........put it on dry, no sealer.........kim......
