It's not the internal trans filter, but the upper Linear Solenoid and the A B Solenoid. The Linear Solenoid has six #10 bolts and the A B has three. It's just under the radiator hose, the other is just below the air intake on top of your tranny. When you take off the Linear you will see four metal tubes (different length, don't mix them up) about straw size in dia, about four inches in length. At the end of each one has a wire mesh screen. The second one is the one that usually gets clogged. The other solenoid under the air intake has a rubber gasket with two wire mesh screens. I'm on my fouth tranny. When it started acting up again, I got fed up with dishing out money so I searched on the net and read about these two shift solenoids. I cleaned them and sure enough the tranny was working again. six months later it started acting up again and I cleaned it again and it was fine again. There was residule crud in the fluid lines so it clogged again, but since the second cleaning I've been driving fine (40K+ miles).
#2219 of 2392 Honda Tranny Possible Fix
Apr 26, 2012 (6:48 am)
hilapat post 2211 What you're describing, is exactly what was happening to my trans. I had to do the same manual shifting to move around. Clean those two shift solenoid screens (Linear Solenoid and A B Solenoid) before you burn the clutch plates and bands (major overhaul at that point). Those two solenoids are on the outside of your tranny on top No need to drop or open up the tranny. If you're handy, you can do it and it's about a 3 hr job. check the wires that goes to the Linear Solenoid, if one is broken or if it is defective, you will get a flashing "D". Personally I feel this is one of the main reason for Hondas Trans going out.

the solenoid screens are most likely not your problem. if they are plugged up, you have much deeper concerns with the transmission. the most common failure on honda transmissions is the torque converter clutch failing. Honda has a problem with the converter overheating causing the converter clutch to come apart. then the clutch material will saturate the fluid ending up in the internal filter. when this happens the transmission becomes starved for fluid and is not able to apply other clutch packs in the transmission, which in turn causes those clutches to burn up and fail. THIS TRANSMISSION DOES NOT HAVE A BAND. It has a series of clutch drums that when activated lock a hub to engage that specific gear ratio. These honda transmissions actually resemble a manual transmission that has been converted to a automatic. the shift forks,syncros and sliders that you would normally see on a manual transmission have been replaced with a hydraulically controlled clutch drum but the result is the same. gears are engaged and disengaged unlike a traditional automatic transmission that utilizes BANDS, planetary gear sets and sprags(one way roller clutches). Getting back to the possibility of plugged solenoid screens, if they are plugged, then no doubt there are screens inside the valve body(deep inside the transmission) that will also be plugged aswell. There are also feed pipe screens inside the transmission that will be plugged up as well. What you really need is a professional transmission rebuilder to overhaul the transmission. there are upgrades that can be installed during the rebuild that will increase the life of the transmission by fixing the torque converter cooling problems all these hondas have.transgo makes a shift kit that allows better trans cooler flow, better torque converter apply pressure, and cooler flow in park and neutral. Sonnax also makes upgrades for the valve body that also prolong the life of the transmission.and talk on the street says superior(shift kit manufacturer) is in the process of making a complete fix for the honda transmissions that will be hitting the shelves this year.if you have a dealer rebuilt transmission installed you will no doubt have the same issues 3 or 4 years down the road as honda does not install any upgrades to prevent the converter overheat issue.

Thank rj28, about no bands in the Tranny. Never opened a Honda Tranny and I was speaking from the GM Trannys I opened up before. I'm a do-it-yourself BYM and the two solenoids I mentioned are controlling the clutch pressure. To some, including myself who are on their second to fourth tranny rebuild, considers the milage and age of our Oddy verses the cost of another complete rebuild again. This is a POSSIBLE fix because myself and others have found that it has extended the life of our tranny. Of course if there are other things wrong, yeh, it won't help. But it cost nothing or little if you're doing it yourself. I had to do it twice because there were more debris in the system, but to date it has been running since the second cleaning. I did have to buy the gasket to the Linear Solenoid second time around for under 3 dollars.

mmmmmm. I am not mechanically inclined, but I could take it to where I usually have my vehicle serviced (not the trans service place...right?).
I wrote everything down, and saw what ri28 wrote to you. The "D" was flashing today, but then stopped. Therefore I am hurting the vehicle more by not fixing now? I was going to wait til the trans went completely out and then take it.
Please advise and thanks for writing...I do appreciate it ;0)

A trans shop will recommend tear down and rebuild... a rightly so. Their reputation as a professional licensed mechanic is on the line. They do not want to do a partial fix and have you come back saying something is wrong again. We do not know at this point what the tranny's condition really is. If the tranny has not significantly burned away the clutches, then just cleaning the two solenoid screens may just all you need to extend the life of your tranny. So the mechanic will be doing labor, unless the Linear Solenoid is bad. Check online for Honda Odyssey Linear Solenoid for best price and cleaning. Your search may even show videos of people who do-it-yourself cleaning them (I did see some about 6 months ago). I would drain the tranny of its 3 1/2 quart of ATF (Use only Honda ATF ~ about $8/qu) and refill, when the mechanic removes the Linear Solenoid to suck up debris from the removed tube passage. Be careful not to nick the tubes and lose the o ring gaskets (4 removable tubes and 4 rubber o rings). You may want to go to Honda dealer and buy the 4 o rings and the the gasket for the solenoid (I would recommend it), but if the mechanic is careful you can reuse, but the cost is not that much, maybe less than $5 - $10. I would not use any solvents to clean the screens, just air blow it clean. The A B Solenoid has 3 bolts, the last one in back is the hardest to get at has the rubber gasket with two screens. When pulling it off from the solenoid, be careful not to tear it. I'm pretty sure it will be clogged, since this is the one that controls Torque Converter pressure. Again just air blow it clean. It can be reused, but if you're concerned replace,but I don't know the cost of it. Post and let us know if this solved your tranny problems.

The problem is that the Honda tranny for the ODY was engineered poorly and no matter what you do it is bound to fail. It started in 2000 and continues today. Honda knows it and does not care. They have replaced entire transmissions for owners because of a class actoin lawsuit they lost. They too fail shortly after installed. The new ones are no better than the old. The only fix is to simply rid your self of the van, live and learn and stay away from Honda.
#2225 of 2392 from auto trany to manual : merical of honda
Apr 27, 2012 (11:59 pm)
after 2 years of lugging and kikking, the 2000 oddy i have owned for the last 3 years is becoming manual tran. van.
now, at take off no problem, second gear will not engage , grrrrrrr, 3000 rpm and no second gear, now what? you move to N , then to D again and second shift is engages, sluggish but it is there. you move on, and third ang fourth again slow but engage. on highway at 70 miles per hour, and 2000 rpm, you can not believe it has any problem. the killer is when you are in traffic , then you want to get your head out of car and curse honda in his grave. but again, everytime you stop you have to bring it to N, then D/ < it will move without doing that, but very sluggish, taking off at high gear feels like. and one more, for a while, the reverse gear will engage only for first time, if you need it again , you have to turn engin off, and on and reverse, voilea.. but now, reverse works fine, no prblm anyone wants to buy my van??? dan

There is a class action lawsuit against Honda regarding the Odyssey transmission problem. You can search for more details.

What years does the class action lawsuit include?
I saw the one for the 2005-2007 (I think).
Do you have a link?
