transmission pan sealing

I myself always get a filter kit a NAPA the black gaskets. You put all the bolts through to keep the gasket in place while installing. That is why the holes are smaller and hold the bolts. Do not use any sealant and make sure you dry both surfaces with brake clean.

I agree with the tube o-ring or lever seals leaking also.

Yama-bond and Honda- bond are the only sealant to use on a trans if you need to. We build two strokes. That is what is used to seal case halves. They must be sealed tight they run off of the fuel compressed through the transfer ports from the bottom of the piston going down. They need to be sealed tight . That stuff works.
