03 V6 2Door Auto Transmission Filter change

[TonyWare]

I changed that little filter today. The one that came out after 100K miles, seriously, it is an environmental hazard all by itself.



A little video of the nice new pink one going in.



A few notes:

• The old filter is hard rock solid, doubt anything can flow through it.
• No difference in tranny performance, wasn’t expecting any (changed the oil too, still smooth auto shifting as usual).
• There is only 1 washer that goes on the big 17mm bolt (that allows the oil to flow in to the filter)
• The 3 little 10mm bolts that hold the cover of the filter housing in place don't need washers, or at least didn't have any.
• The bottom bolt of the housing wasn't easy to remove even though all 3 little bolts appear to have anti-seize on them from the factory.
• There is a spring behind the filter in the housing, not that hard to put it in place by "feeling" if it is in place as you put the filter in.
• To get to that filter you need to remove the stock intake filter box (mine is already gone since I have a CAI).
• All stealerships in Ottawa now think I am stealing food from their kids mouths. They should have known better not to #$&^%$#@#%^# with me in the first place.
• Do it.

Parts used for the 03 v6 auto H5 MAYA (could be MCLA) transmission:

• 25450-RAY-003 Element ATF
• 91301-RAY-004 O-RING (48.5X2.95) (ARAI) ... hard to get
• 91302-RAY-003 FILTER, GASKET
• 94109-12000 WASHER, DRAIN PLUG (12MM)

As always, a huge thank you to NVA-AV6 (... from another forum) for pointing out to us that there is a filter after all

... went out driving, had a double-double (Canadian secret word LOL) and came home to take a hot shower and my back is killing me!

double double inn n out?

You rock, this is going in the FAQ

[TonyWare]

Day after... I have a habit of checking everything a day after for leaks etc etc.

Visual inspection around the filter housing and under the car: I left a large piece of cardboard under the car overnight after I drove it and this morning I don't see any stains on the cardboard. Easy and quick test for leaks. Also, both the engine oil drain and transmission drain bolts are dry no signs of oil on them.

However, here is something odd. Wikipedia lists the 03 accord with either a MAYA, MCLA or MDKA transmission. I checked the label on mine that is somewhat visible (the bar code on it is almost whipped out but the serial number still visible) it says BAYA. Wikipedia lists the BAYA transmission next to the 05 Accord Odd. Wikipedia may be wrong but still have to cross reference this with other source. Any ideas about other sources? Did Canadians get a better deal with the “good” transmission vs. the “bad” transmission that was installed down south?

... key word for Canadian coffee, think of Starbucks but with the added element of transmission oil, brused hands, frozen noses, bad back etc etc

Code just tells you which engine its for and where its built. I think Wikipedia is wrong.

I suspect that due to North America Free Trade regulations, Accords that are made for export to Canada have the BAYA (the US made transmission) on them. Something to do with cars that must be 100% made in North America to be able to cross the border to Canada duty-free for the manufacturers only. Whereas in the US, Accords made for local selling may have the MAYA (Japan made transmission) on them simply because they aren't made for export to Canada therefore they can be less than 100% made in the US.

Correct me if I am wrong but most of the issues we have been reading are with the MAYA, Japan made one? Too many forums, too many "opinions"... wish we had someone from the inside Honda to tell-all, wish!

(yeah, I think wiki is wrong, or better: confused)

Nice DIY. Good job and glad you got that thing changed....looks disgusting.

Bringing this back from the dead! Thanks a lot TonyWare, this was extremely helpful, so I'm bumping this back up incase newer members have not had a chance to see this.

A noticable difference in shift smoothness, and I only have 56k mi.

[TonyWare]

The once a year, at least by my standards of driving, transmission filter is done. I like to keep an eye on the cover for a few days just to make sure there are no leaks even though I changed the o-ring. The old one that came out, once again, is disgusting! What I noticed this time around that there was more crude oil stuck on the filter and the drain bolt. Sign of trouble? Well, it still shifts fine and is smooth, some 220K km later. Pics of the work at random in the photobucket album

You sure it's crude oil? It looks like metal shavings to me. It's normal to some extent but of course is a bad thing...after all, that means some part of your tranny is wearing down to shoot all that metal into the fluid. My Magefine off my Ody 4AT looked like that too.

After 10K miles/1yr 5months, a period in which I changed the fluid THREE times


That's the magnet in the filter, caught a ton of metal particles (that I wiped onto the paper towel)


But, differential half shaft bearings still feel pretty tight, and I've heard that is one of the things that tend to wear out and cause failure...so I think mine is still doing okay I guess it's better to have all that crap on the filter instead of in the fluid.

[TonyWare]

The drain bolt was definitely crude. Unless these metal shavings are so small that when they mix with oil you can't tell! I did wipe it out on a towel too and didn't get the impression there was any metal in it. The stuff you see stuck on the filter, is actually the paper of the filter deteriorating. One thing for sure, not in the same condition as a year ago both bolt and filter I changed last time but a little less clean.

Ya the metal shavings are really tiny, and the drain bolt is magnetic...so I think it is metal.

I just changed the filter on my 03 V6 sedan, and I have a couple questions.

On the feed pipe there were two washers, one on each side of the pipe, right.?? I just re-used them (no leaks)

Had you changed the filter before this (100k miles)? How often have you changed the fluid?

That bottom bolt was a big pain (in the back) until I finally figured out how to turn that ****er.


Thanks in advance

Sorry for he delayed response but somehow I missed that thread question and someone else referenced it recently so it came back. I changed the tranny oil every 50k-60k km (around 34k miles) and the filter once a year regardless of km/miles. Yes, that bottom bolt needs special attention. No need to change that washer unless it is visible bad but do change the o-ring around the housing filter cover.

Would you know if an 06 V6 Canadian sedan has the same trans filter parts, used for the 03 v6 auto H5 MAYA (could be MCLA) transmission? I'm from Winnipeg Manitoba.
Maybe Princess might have something listing if trans are the same?
My trans oil change is coming up soon. I have 87 KL now on it. Honda say it is due at 96 KL. I want to get the filter done as well if I can
