I changed my auto tranny filter a little over a week ago. My car had 42K on it and the filter had not been serviced to my knowledge. I replaced it with a Magnefine 3/8" inline filter, but the Honda filter seems to be well made. I purchased the filter @ www.emergingent.com. Click on Magnefine, and then Online Store. (The smart connects are for attaching to copper lines, not needed in this install.)

I immediately noticed quicker shifts under light acceleration. Before at a steady 50 mph it would seem to be waiting until 55 or 60 to shift into 5th. Now in will shift into 5th at a hair over 45 with out hesitation.

I got a few pics of the new filter in place and the old one cut apart. The media is covered in the same non-gritty sludge that sticks to the magnetic drain plug. There was some grit captured in the filter as I tried to get a pic of it.
Here's the old filter.

Old one cut open, note the bypass.

New one zip-tyed in place as it was too fat to fit under the bracket.

by the photo's provided above the magnefine has a much thicker circumference, I guess that equals to better filtration. I am thinking of changing the AT-filter to a Magnefine filter for my 2.4L AT and if i wanted to change the filter on a V6-AT model, any advised from fellow v6 owners the type or a quick write up from fellow owners.

Thanks
George

Why didn't use just replace the filter & not the whole thing?

I am pretty sure he had to cut that filter housing so you could see the filter media inside of it.

 

[Aviography]

It doesn't look like the internal filter element can be replaced? OP said he had to cut open the filter.

Did Honda start adding transmission filters back on the 7th Gen again? From what I recall the transmission filter is not serviceable as it is inside the transmission.

 

[Marc04LX]

I did cut the old one open. The Magnefine is only slightly larger, but it is longer. All 7 gen automatics have a servicable filter. The V6 models are a bear from what I've read.

Sorry about the last pic, I didn't notice the blurring until I posted it.

 

[iccord]

But is it the same part for the V6-AT as the I4-AT ?

 

[Marc04LX]

Oh no, it's different on the V6. Somebody here has done it though. Keeping searching and you'll find something on it.

 

[Bruce Hawkins]

Look like this could be added to any Gen Honda, no?

 

[npolite]

Can someone post the factory instructions on replacing this on the gen 7 and if it is in the gen 8? I checked on Purolator's web site and it says it is not serviceable.

 

[Marc04LX]

Changing this filter is very straightforward. Locate the filter. Look to the left of the air filter housing and back some. It's attached to the tranny housing by a single 10mm bolt. The wide 3 point spring clamps are the biggest obstacles. I used a set of locking needle nose pliers on them.

Remove the hoses and remove the bolt holding the bracket in place. Re-assemble in reverse order and add fluid as needed. Think fuel filter on a non-pressurized fuel system

I had a Honda dealership tell me my car didn't have a servicable filter, but I've seen a diagram with part numbers on this site somewhere.

no instructions but here parts page and pic for Gen8 2.4L.

The filter is right on top case held by a strap clamp, you can't miss it.

I've had mine on since the 2k mile mark. IIRC it says to change the Magnefine once a year. Regardless, I'm changing mine every 20-25k. Nice pics Mark, glad it worked out for ya. I'll cut my Magnefine open when I install the new one and post it.

That's a tranny filter?

That's just an external line filter to trap sediment being circulated through the cooler line I would assume. Most cars have a much bigger flat filter in the bottom of the trans, perhaps 6" x 8" square. In my F250 it was about a foot long. I can only hope the Honda has something more substantial inside it or it explains a lot of the problems they've had.

Honda doesn't list this as serviceable, but it is.

You can't just replace the filter. It's completely sealed so you have to replace the whole unit.

For whatever reason Honda doesn't use those type of internal flat filters used in US AT market.
Its better than nothing and still filters all the tranny oil. It works just like a fuel filter or oil filter as there both inline filters too.
It is odd they don't recommend changing it at any time intervals.

I called 2 dealers in my area and they both told me the filter did not exist at first. After I asked them to look further, they finally found it in their parts lookup. Interestingly enough, both dealers never sold one to the public nor used one as a service replacement. Go figure.:dunno::scratch::screwy:
