Your magnets will only capture steel and cast iron particles. The filter is meant to keep out the big chunks and any friction materiel which is a natural by product of the aging of the automatic transmission, not metal. You should not expect to catch much metal, especially magnetic, although you will see flecks of brass and bronze from the thrust washers as they wear normally. If you find large amounts of friction materiel or any significant amount of magnetic particles the transmission is nearing the time for a rebuild. If at this point you continue to drive on it you will only cause more damage, like driving on a worn out clutch, it tends to wear much faster as it approaches the end of it's life. When the fluid becomes overburdened by particles it wears out the pump, the seals, the torque converter, and the thrust washers and shims. Even if you reseal they won't last if the fluid is full of grit (microscopic particles of metal and friction materiel). The only cure is complete disassembly and replacement of all of the wearable parts, the friction plates, the steel plates, seals, bushings, thrust washers, and gaskets. If you drive the trans to destruction then you risk of ruining hard parts like gears, housings, shafts, etc. These parts are not normally replaced and are expensive. Think of it like driving on worn out brake pads and ruining the rotors. If you stopped and did the pads for say $50 you wouldn't have to go for rotors for $500. On the Delorean you cannot properly flush out the trans fluid unless you dismantle it. Too much remains in the torque converter and you can't drain it without removing it. Cleaning the filter is involved but since there is no more stock and I cannot find a replacement this is the best I can come up with.
