My remote spin-on filter setup is from B&M while my cooler is from Hayden. The transmission fluid is filtered from the transmission before it enters the remote transmission cooler. With this setup, I can change the "oil filter" easily by just spinning on another filter....anytime. Thus, with removing the cooling lines to the bottom of the radiator, I have eliminated the possibility of the "strawberry milkshake". The radiator and transmission fluids mixing due to failure of the transmission lines/radiator cooling lines, OEM setup, was a weak point in my 3rd generation 4Runner, SR5
The cooler is mounted in the front of the radiator, attached to the frame at a 60-degree angle so air can flow over, under, around and through the cooler. I passed on the "plate and fin" model since it would restrict air flow through the cooler. Instead, I opted for the tube and fin cooler model in a serpentine design
The angle of the cooler is not pretty....but IMO.....more efficient rather than having it mounted flush to the radiator. I used spring clamps for all of my connections rather than the "screw down" type. These will expand and contract automatically with heating and cooling of the hose lines.
Next, on my projects list, will be to remount the oil filter assembly to the inside of engine compartment using the hydrolic hoses, fitting and a remote spin on filter setup from Hayden. This will make changing the OF easy like changing the external transmission OF.
I'm using an oversized Mobil 1 EP, OF on the remote transmission mount. IMO....Any filter is better than no filter.
I would like to know what you find in the filter if it was cut apart. The only thing I see (with my eyes, not a microscope) in the Magnefine is a lot of steel paste covering the magnet. Almost nothing in the actual filter media. Now the Magnefine filter media is 30 microns and your filter is maybe 15, and its possible there are many very fine particles stuck in the media of the Magnefine (too small for me to see). But I think the magnet does remove stuff as the ATF is forced past the magnet. This observation is from 3 or 4 Magnefine filters I have opened up.
I should note that in all these cases, I have been using Amsoil ATF, so maybe I should not expect much to be caught in the filter as there is not much to be caught.
