In my high mileage Camry transmission, the Amsoil ATF fluid looked fine, but the Al was high and the Magnefine did not catch much of the Al, probably because the media filter of the Magnefine is a bit on the coarse side. If the particles would have been metallic then the magnet would have caught them, but not Al.
As others have said, color of the ATF is no guarantee.
But unless you have a big truck or Suburban, then no room to install a finer spin-on filter.
