Well more of a unscrew than a cut open:D Anyway, I decided to go ahead and change the magnefine trans filter on our 97 caravan since I noticed some of black stuff starting to show up on the dipstick again. The filter has 22,858 miles (11 months) on it. When I originally added this filter, I also did a pan drop and replaced that filter as well.

The new filter I just swapped it in and topped off.

I was surprised how much it had accumulated. The pleats were gritty unlike any other filter I have cut open.

I'd say I got my $$ worth out it :P

i was surprised how strong the magnet was. stronger than most pan magnets I have come across

I wasn't sure if the pleat pics were gonna come out with enough detail. so I tried a new (to me) method of showing what the pleats caught. So on piece of paper I rubbed about 1/5th of the pleats around on the paper:

Looks like you got your moneys worth, and a cleaner transmission.

Thanks for the pics! Clean the donut magnet and put it in the trans pan next time you do a pan drop.

Nice photos. Did the stuff from the magnet look and feel like Neverseeze when wiped with finger? (Greasy metal).

What were the particles on the filter media? Metallic (but not Fe) or clutch material?

Has anyone done any calculations on the increased flow restriction of adding one of these filters and if the transmission doesn't get enough (cool) fluid as a result?

It is theoretically possible that you get increased wear due to less (cool) flow.

I changed a transmission filter after 66k and it wasn't that dirty.

Ford thoroughly tested Magnefines (even installed backwards) and found a negligible drop in pressure, IIRC.

Typical in-pan filters are more like rock catchers, I read that the best ones filter up to 80 microns.

yeah the magnet had the same metallic goo as a pan magnet.

Great idea about reusing the magnet, didn't think of that!

Forgot to mention this van has 245,000 miles on it now. So maybe the next magnefine will be cleaner?

Wait a minute, your transmission has a spin on filter ?

I'm really glad I have these on the majority of cars I service!

Makes me feel warm and fuzzy. smile

Nice thing to see a product is doing it's job. The magnet gives the Magnefine a good edge over other things. Some 51 percent of all trans contamination is ferrous and though the Magnefine fitler is only 35u, according to the engineer that designed this filter, the magnet catches some 99 percent of the ferrous particles of all sizes. For that reason, the Magnefine is somewhat more efficient than its filter media efficiency would indicate.

Was this the first run for a filter on this trans? If so, it will likely be cleaner the next time.

Does anyone know if a replacement filter cartridge is available for these? Since the top unscrews I wouldn't mind just cleaning the magnet and replacing the filter element rather than having to purchase the whole thing every time (it seems like a waste).

Yes, because Magnefine also offers an aluminum housing "performance" version that uses the same filter. Anyplace that has them should have the filters too. <www.emergent.com>

The only places that have the replacement filter cartridges are charging $20 for them. I'm buying the entire filter for $15.49 so it doesn't make any sense. I figured that if I could buy the cartridge for something like $7 or $8 it would be the way to go.
