Ya I had the same thought after I cleaned all the metal bits off the screen. Just a guess, but they looked to be aluminum. Yes a magnet in the pan would be a good thing, perhaps the next time I pull the pan off I'll put one in there.

Speaking of which... in the WSM it tells you to unbolt the expansion tank from the pan and then undo the coupling between the tank and the pan and leave the tank dangling from the trans by the vent hose. I have found it is much simpler to leave the tank attached to the pan and just pull the vent hose from the trans.
