2004 accord 4-cyl: ATF filter?

"Lifetime" often means different things to the manufacturer and to the
owner. How soon do you start getting discount flyers trying to get you
into a new car? And maybe 2x that interval?

Magnefines, like many oil filters, have bypass valves built in.

"Will it clog?
Magnefine double filtration is so efficient it removes 99% of all wear
metal contaminants. It¹s design holds the majority of contaminants on
the uniquely positioned magnet. Even if the filter element becomes
full, it¹s safety bypass opens for full flow and the magnet still
cleans metal from the system."

Do a google on magnefine pictures, you'll see one cut open from a
truck. Dirty I'd say.

no, i don't have an answer for _you_.

no - one of us did some homework. and it wasn't you.

i seriously doubt those failures were filtration problems. honda
transmissions were able to manage 300k+ miles on just one filter before
so there has to be some other change going on for that filter to
suddenly clog. my suspicion is a change in material spec leading to
substantially increased wear. filter clogging would be a symptom, not
the clause.

please - all this is unnecessary if the transmission was built and
spec'ed right in the first place.

Of course... :-)

you don't get it. you **** and moan, you complain, you deny, and worst,
you make stuff up. you don't /actually/ want "answers", you just want
to remain ignorant. for your future one-way communication needs, i
suggest you go watch tv.

I was not going to use magnefine, rather factory replacement.
I understand it will have the overflow path, as well.

So the fear about overheating fluid can be erased from discussion :-)

Exactly my point... this is not a term which is precise enough to me.
