Hi all,

Just wanted to give an update of the rebuild, process and lessons learned. The van has 147,500 miles, first transmission and was having delayed upshifts from 1st to 2nd and slipping in 2nd.

I opted for a home rebuild instead of the $5500 quote from Honda and $3500 from a local shop.

Here's what I did:
  • Master rebuld kit - seals, gaskets, o-rings, steels and clutches (CT Powertrain - great place!)
  • Honda Filter
  • Magefine inline filter
  • Hayden 678 External Cooler
  • Recon torque converter (CT Powertrain)
  • Complete dis-assembly of every valve, servo, ect.
The whole process from start to finish took around 44 hours and cost about $900 in parts/fluids. Pictures of the work in progress: click here
If you really interested in the nitty gritty price breakdown you can view it: click here

Overall things went smoothly, it runs and drives great. Here's the good and the bad...

The good:

  • I used brake cleaner and compressed air and lint free automotive towels to clean all of the parts which worked well.
  • Trans gel is a must for lubricating the parts
  • Air tools (Harbor Freight) made the job so much easier
  • Shop manual is a must! That saved my life so many times
  • Zip lock bag and tag every set of parts and take lots of pictures
  • Get a nice inch pounds and foot pounds torque wrench
  • I opted to make a mount for the cooler rather than using the zip ties that came with the kit. I found some foam for water heater pipes that worked great for keeping the cooler lines protected around the frame
The bad:

  • The sub frame was a bear to drop and maneuver around. I opted to support the engine from below instead of hanging it and if I had to do it over, I would have constructed a support system on top of the engine compartment.
  • I tore both lower ball joint boots - buy the $20 non-destructive tool from Harbor Freight. Thank you Honda for making replaceable boots! ($27)
  • I broke the front right motor mount from all the stress of lowering and raising. A top support would have saved me $47
  • Honda sells a input shaft holder for around $50, if I had to do it again I would buy it
  • Buy, beg or borrow a nice torque wrench that goes up to at least 166ft lbs. I bought a cheap one and I over torqued gear and busted a bearing which cost me $10 - but could have been a big disaster
  • Take your time and read each step! I installed the 1st gear clutches in the 2nd gear spot and had to redo during the build which cost me an hour.
That's about it, hope you find this info informative and give it a go for your van!

I forgot to mention that I installed a valve body mod kit by Transgo called their Honda Lube Kit. It's supposed to help with TC overheating. Here's a link from their website: TransGo | Honda-LK

I recently bought an 01 ody with what I was told is a bad trans. I drove it for 3 days before it faulted and it took about a 40-50 miles non-stop trip to do so. After limping it the rest of the way home it sat for a couple of days and I decided to see if it would move. It drove fine no slipping or faulting. I've done this several times with 5-10 mile trips and it drives great. My question is, since it seems to be fine on short trips do you guys think I could get away just replacing the filter inside the case? My thought process is, that the filter just builds up material until it becomes clogged? I know I can split the case and change that filter (with the updated filter) but im not comfortable with bothering the clutches. Please help, thanks.

It needs a complete rebuild. Just the filter won't help. I have rebuilt 2 of these. The filter is so deep inside, if you aren't comfortable with clutches, you won't be comfortable with the filter. You're always welcome to try though.

I don't think that replacing the filter will be the magic bullet. I've rebuilt two of these transmissions as well and I completely agree that a total rebuild is in order. Honestly, the most time consuming portion of the rebuild is the removal and re-installation of the transmission which would need to be done in order to replace the filter. If you're unsure of doing the work yourself try looking on craigslist. There were some transmission shops advertising deals for odysseys.

Good luck.

breathtaking pictures. and job
you got to have worked in a shop before.. no one would be able to touch this without the experience and confidence.
It was great to see what actually is inside the odyssey transmission housing .. a huge thanks to you.

I noticed you have a transcooler .. do you feel having a transcooler on this van for regular every day use (not towing) would be beneficial to the van in any way? or is there no benefit

I think that the cooler is essential to having any longevity to your transmission. The transmission shops that specialize in rebuilding the odyssey will not install a transmission without a cooler and magnefine inline filter. Heat kills these transmissions. Overheating torque converters and burned clutch packs can be minimized by installing an aftermarket cooler. I used the Hayden 678 along with an 3/8" inline magnetic filter (magnefine).

So,I decided to heed everyone's advice have the transmission rebuilt in my ody. The shop I work for deals with one local trans shop. He originally gave me a very reasonable price to rebuild it. I called him earlier this week and he told me he would work with what I had since we send him so much business. If you guys hadn't advised against it I probably would've tried to just replace the internal filter. Just wanted to say thanks. As soon as I get it back I will be installing a canister filter and fined external cooler. So much great info on this site. Thanks again.

After looking at your illustrations of the rebuild job I have now decided to attempt this job as well. I do have a few questions though. Where did you purchase the manual and do you have part numbers for the seal puller and bearing puller.
One more thing of note, As it appears you used no special tools what-so-ever. Is this correct? I already have the harbor freight 12 ton press ,trans jack and the topside engine support. After you made mention of breaking the bearing I may want to invest in a higher quality torque wrench as mine is +-4%. I am also curious to know how the repair is holding up.

thank you you in advance

Ez auto- the manual is a Helm. The website is helminc I believe. They were out of print when I had to get mine but ebay usually has a few. Accept nothing less. You'll need it.

Ezauto, and anyone else attempting this, my best advice is to do as much research as possible. I spent about a week googling "b7ta" (or whatever the code is for the 02-04 if applicable). Look up exploded diagrams, and get the manual and read over the entire trans section several times to get a mental picture of what's going on prior to getting dirty.

As for the special tools, I did mine without any. I only fabbed up the top side engine hanger and the clutch pack press. I didn't even touch a tq wrench. I do recommend the main shaft holder, I wish I would have had that. I just used an impact wrench.

I bought the master kit from transtar but I recommend getting the main case gaskets from the dealer. I had the grey paper case gaskets leak once-pretty frustrating after the whole thing is all back together. I've had good luck with the white, green coated, genuine Honda case gaskets.

Regarding the press and bearings, it would certainly be nice for the bearings on the shafts, your lucky to have one.. I use my "hammer and 2x4" press a lot. For the bearings in the cases, just hit the cases with a heat gun or propane torch and they drop right in. They don't need the old oxy acetylene red hot treatment, just a little heat gun action and the drop right in.

Sorry for the random shotgun of thoughts, I'm typing while wrangling 3 toddlers and a newborn. (don't postpone those vasectomys guys)

This is the one! Sir, I think you can do much better than their $129 asking price. Do a little searching; there are used ones out there.

With out a doubt. I just wanted to make sure I was on the right track. I have seen a few of you mention the main shaft holder. Where can I find one of these and is the cost justified? I have no qualms spending money if it will ease the amount of effort significantly

EZ, I've never had one of these apart before, so I do not know what tools are absolute essentials.
