What validates the complexity for me is that even ex Honda tech ERICTHECARGUY failed at trying to rebuild his own trans

If you have the time and space to do the swap yourself, I would encourage you to do so. Find a 3 year warranty, dyno tested, remanufactured one with upgrades done inside to improve flow. Having done this myself back in 2018 I think it was worth it and the best choice I did. The other options was to rebuild it myself ( which would have cost the same-probably more and much longer time to finish) or have a local shop rebuild it with only 1 year warranty (quickest and least hassle). I have only driven it about 14K since but its been smooth shifting and problem free so far. Hence the longer warranty was more valuable. Look here....new how to remove transmission video coming, step by step

Whichever route you go, its a gamble. I will never get a used one from the junk yard. Generally it should cost between 2-2.5K. The more expensive remanufactured ones (3.5-5K) you may see around, usually cost more because they change all the external sensors. Which most are reusable and works perfectly fine. You need to test its function before reinstallation of course. Good luck.

Junk yard is a bad gamble, I agree

The lack of warranty makes the JDM transmissions not worth it to me at least, and they are not that cheap

I got my 99 trans rebuilt by level10 a few years ago. So far it's been fine. Yeah a few bucks more but sometimes you get what you pay for. After reading all these posts about transmissions on this forum - I would only want a Honda trans specialist to do the work.

Semi side question, would this be a filter the dealer put in for previous replacement? View from the top

Is it an upgraded rebuild? , would be fun to floor it whenever one feels like doing so :D 🆒

Why not just try the fluid change? My son “changed” my daughters transmission fluid in her 2000 accord but since he had no clue drained the transmission fluid and added 5 (it only holds 4) qts of oil. He then proceeded to drive it around with no transmission fluid. Eventually transmission started slipping so he decided the fix was he put too much oil in the car so he drained more transmission fluid and drive the car some more. At this point I assumed transmission was toast. It was slipping, not going into gear. 🙄🙄
After sitting for 1.5 months, I was teaching her a lesson about having inexperienced people touching her car, I added max life trans fluid. Ran it through the gears, did a drain and fill, drive the car and it finally drive and shifted but it was rough.
I then removed the return line, drain the fluid 3 qts at a time while adding new fluid, ran a total of 2 gallons through, then added a magnefine after all the fluid was clean. The car shifted better and she was able to drive it without all the jerkiness and slipping. This was Sept 2020.
4 months later I did another 2X drain and fill in Jan 2021. I just did 2 more drain and fills in Aug and also replaced the magnefine. It has been 10k and transmission is shifting fine, the only issue it has is that it jerks on occasion when coming to a complete stop and if you drive like a maniac it slips going from 1-2.
3 gallons of max life and a few hours of my time.

As mentioned in previous post. Ask, and ask, and ask, local mechanics. Who in your area, do they know, is the best
"tranny rebuilder". Also, if you see any generation 2 odysseys in your area, Ask the driver, "how many transmissions?"
To get the conversation started. Then ask they, who did they use, and was it a success. (y)

It is suspicious all gears slip. to me I wouldn't assume the clutches themselves have been worn out. I would first suspect that the new fluid is garbage and is causing too much slip. I would pull the ATF line from the radiator , the one on the drivers side that you can see if looking straight down, that's your ATF return line, plug in a new hose and stick the hose in an emptey container. while someone turns on the engine let it run until the split second no more ATF comes out. than refill it with new oil, try maxlife ATF, I know it works, and it's $18 from walmart or their website. if that doesn't fix it there is a double solenoid on top of the trans and one has a plastic screw, that adjusts the pressure for when the trans does it's shifting and engages the clutch plates. someone would have had to tamper with that for every gear to slip. otherwise all your clutches are destroyed which I've never heard of, it's usually just 1 clutch that's destroyed, but again anything is possible if you abuse your transmission by smashing the gas down all the time

Thanks EK. I'm really curious about the "extra" transmission fluid I took out after it running for a month or so. It leads me to believe the TC is jacked or possibly the pump. I'm going to borrow a pressure tester from one of my mechanic buddies and see if I even have any pressure. If there is pressure, I may go further with the fluid ideas. If not, well, I assume all is lost.

I have called locally and one shop quoted $2000-$2500 for the rebuild and install. Another wouldn't quote a price, but shared an average of $3000. Talking with him was rather good, as he spoke of Sonnax upgrades and other items that have been mentioned here.

I'll keep trying things I can do here at home for now. Unfortunately I'm pretty wrapped up $ wise with my MIL's house as I rebuilt it this summer and took the burden on my shoulders way too deep. I actually had a pretty rough day yesterday with all of it, our other car had a nice puddle of coolant under it when I got home from taking my daughter to school. I'm willing to admit it, I broke down with it. Finally I went downstairs and got alone with God. I had to give it all to Him. I can't handle it right now. I've just got to leave it in His hands and pray for my yoke to be lightened.....

Your son drained the fluid and added 5 qts and then ? the transmission started slipping?
Next, you say "He then proceeded to drive it around with no transmission fluid".
He overfilled it and somehow drove it with NO transmission fluid?
Very poor explanation on what really happened but happy that you got it going OK.
Very possible that your daughter's car had some transmission shifting problems before your son did the drain , etc.
You doing several drain and fills probably solved a problem. Very confusing.
