transmission pan sealing

You may look at what the motorcycle community uses to seal engine cases. I once had an old classic m/c that had a case leak I couldn't stop. A buddy gave me a tube of 'Honda Bond 4' and after applying the sealant it stopped the leak.

A thin coat on both surfaces applied with your gloved finger is all it takes. It doesn't dry completely so you can later separate the pieces.

Good luck as oil leaks are a P.I.T.A.!
