Here's another example of why you may want to add a Magnefine filter to your transmission. This picture is from my wife's Merc Villager. It now has 129,000 miles and this filter went in at 90,000 miles. I always did an annual drain and fill and last year did the flush. All of the black on this paper towel is metallic particles that would otherwise be flowing through the transmission fluid. Its so abundant with metal that the magnet can pick up the paper towel. This can litterally save you from a ruined transmission. And keep in mind, all this was missed by the oil pan magnet.
