Question for the engineers out there.
Will JB Weld hold a magnet to the inside wall of the Rockwell Transmission Pan successfully? Not much future in sucking magnet into the working parts of our TH425.
Thinking of attaching one inside pan before replacing pan on transmission. K&J Magnetics has a perfect high temperature magnet for the proposed application. Only problem is sticking magnet to inside of an aluminum pan. Second solution would be to install along outside of pan.

Tom,
While I understand what you are trying to do, I would doubt it would be completely successful. There are two problems with bonding to aluminum. (I have had to do this on occasion.)
One is that any casting is porous and if it has ever been near oil of any kind, it will be a mother to bond to effectively. Even the mold release used in sand casting is enough to foul things up. New rolled sheet stock has to be cleaned and etched to get workable adhesion.
Another is the coefficient of expansion of aluminum is higher than most metals, this may cause the bond to the ceramic of the magnets to shear away a little at a time and finally fail.
I do have some options. If you look around, magnetic drain plugs are quite available and easy to make if you can't find one you like. Or, give Manny a call, and ask him if he thinks a loose magnet on the bottom of the pan will cause any problem. Another choice might be to use stainless safety wire to lash the magnet(s) to the filter pick-up tube.
