I think point 1 is valid but I would push back on point 2, at least until or unless filter specs can be produced.Shall36 made a good point that a Magnefine is redundant as a filter, but IMHO he missed the two advantages of installing a Magnefine:
1. Easier to change than the OE filter, so more likely to get changed regularly (and it's cheaper then the OE filter).
2. Traps ferrous particles that the OE filter cannot, and better IMHO than the magnetic drain plug.
Your Magnefine looks great. How many miles driven in those two years? hat's your city/highway ratio?
Yep...exactly.Good stuff, Shall. I think we Ody owners, especially 2nd gen, are so anxious (and sometimes rightfully so) about our trannys that we tend to over compensate. If indeed the Magnefine turns out to be more or less a placebo on 05's and 06's, then that is one less step to worry over. Hope we get more folks weighing in on this.
BTW, I think you meant to say "...before it hits the OEM filter" (not fluid) at the end of the 2nd sentence of your second paragraph.
I will never trust any oil that claims 15k fluid interval, nor will i ever trust a oil manufacturer that basically uses MLM scheming to be a "dealer" of their product. All the literature is written from them too......and no, i do not beleive fluid looking almost new at any change other than 5min warm up. I've done rebuilds, gotten rebuilds, and changed enough fluids to know this isn't true.Yep...exactly.
From my experience, the best maintenance you can do on a trans is to use Amsoil fluid. I've found the 15K fluid change intervals with Amsoil will eventually get you to a point where virtually no junk shows up in the pan. On the Ody, since there is no pan, my fluid looks almost new at my changes.
Yes, it's the same for Gen 2 5-speeds. Filtered ATF would always flow into the OE filter so the latter would last forever.So I did some research and it looks like the '05/'06 models have the filter on the return leg to the sump. What that means is that you could put a magnafine on the backside of the cooler and filter the fluid before it hits the OEM fluid. In theory, this would keep the OEM filter from getting plugged up with contamination, which would be a really good thing for those '07+ units where the filter can't be serviced easily.
I'm no metallurgist by any means, but I think the ferrous particles in the ATF that come from bearings, gears, and clutch pack steelies are smaller than any filter can trap. That's why the stuff that's on your ATF drain plug magnet is like paste. So the magnet in the Magnefine will attract and hold them out of the ATF.As to point 2 above, that would only be true if either the magnafilter design is superior to the OEM design or the magnafine can filter out smaller particles. I found a reference that indicates the magnafine can filter down to 30 microns. I don't have specs for the OEM filter, but both filters are of the same type (pleated cartridge).
2007 ATF Filter part # 25450-P4V-013 and filter cap o-ring is 91305-PN4-003I went to advance auto, they say no filter as its not serviceable. I go to rockauto and they have the small cylinder shaped element with 2 o rings, a black screw on one and one that looks like a fitting. :huh:
It is on 2005 and 2006 Odys. In 2007 they put a different transmission in (took it from Honda Ridgeline pickup truck).I thought it was under the brake brain box which is under the air cleaner?
