    2003 Automatic Transmission Filter

    This forum is excellent and I would appreciate any help or comments.

    I have a 2003 Honda Ody with 144,000 miles on it - a large majority highway miles. I have heard many horror stories about the automatic transmission on the Ody, yet the Honda dealership looks at me like I am crazy and tells me that the 2003 has no issues like the older second generation odys. He is wrong correct?

    Does the 2003 have the automatic transmission filter? I asked for the dealership to service this and they refused citing that Honda says it is a "Nonserviceable" part. They won't even touch it.

    I change my transmission fluid every other oil change which might delay the inevitable, however can any cite documentation that I can bring to Honda to make them change the autotrans filter?

    Thanks for sharing any insight or similar experiences.

    order the part from one of the popular places (bernardi, etc) and take it to an independent mechanic (that you trust of course) to replace. i would even print off the step by step from these forums and bring it with me and show the mechanic.

    Your 2003 does indeed have an ATF filter. All the dealers toe the Honda corporate line that it is a non-serviceable part. If you want to replace it, you have two options: DIY or indie garage. It's a tricky job. I would want a high level of confidence in the garage that does it.

    Another option would be to install an inline Magnefine ATF filter. It's a much easier job and also with less risk of subsequent problems. The factory filter would probably not trap any additional particles after that.

    Part number is 25450-P7W-003.
    Nomenclature: FILTER (ATF)

    I'm holding this "non-serviceable part" in my hand right now.

    Those guys at your dealer are complete dongs. My dealer (Milo Gordon Honda of Lawton, OK), once made aware that the part existed, gladly ordered me one when I asked for it.

    There are some good threads with pictures with good details on tools needed and how to replace it.

    Thank you ALL for the responses because they do help. Has anyone had success in having the Honda dealership put this part in? And if so how did you talk them into it. I was told by the dealership that they would NOT put it in because it is designated as a "non-serviceable" part.

    I don't trust my ability to put it in myself.

    Thank you all again.

    This appears to be a dealer issue and you might want to consider another more cooperative one.

    I had the dealer install an after-market ATF filter on my 2001 (which does not have the canister-type ATF filter the 2002-2006 Odysseys do) and they had no problems with that. I did this mainly to preserve what, if any, Extended Warranty I had left on the transmission. It is the Magnefine ATF filter (magnetic and paper filter in one) and is easily serviceable now. Best decision I ever made IMO.

    Keep up that ATF exchange schedule.

    There seems to be some debate on what wrench is best to do this job. Some say a flex head and others say an offset wrench. Can someone who has done this recently clarify which is best? Thank you to all who have commented so far.

    I was successful in having a dealer install the AT filter on my '02, and I didn't even by it from them. I got it online, and had them install it during a regular service.

    The service advisor seemed completely non-plussed about it, but did have to walk back to the shop and talk with a few techs to determine how long it would take to install.

    They charged me $50. Money well spent as it would have taken me at least 1.5 hours and I had just had a mani/pedi, and didn't want to ruin it.

    I love this. I went to the parts department today at my local Honda dealer and asked for a transmission filter for my 06' ody and was quickly told that there wasn't one.

    I then asked him to pull up the schematic of the 06' tranny and he immediately found the filter.

    Their own parts guys don't even know there is a filter....

    BTW - Thank you to this forum for all the help! You guys are great.

    Here is the new / old filter. My dealer didn't even know it existed. I spoke with the service manager, who is a 25 year master mechanic and he didn't even know of the filters existence.

    Further he said that since Honda didn't list it as a part that needed service, he didn't see any reason to change them out.

    I ask you, does that look like a filter that needs to be changed?

    With all the transmission troubles the 2002-2004's had, it amazes me that most Honda dealers have no clue about this.
