Are you sure the gasket on the transmission case isn't from the old filter and it just came off when you removed the filter?

I think that you just put the magents in the screen and they are going to arrange themselves any way they see fit.

I don't remember how far the suction screen goes back in but I don't think there is much of a trick to it. I think you just push it back in and then just put the cover(not sure what else to call it) back on.
