Hi all,

First off, thank you for this incredibly useful site. Its been a pleasure for me to lurk and soak in the knowledge shared here.

I've got a '00 EX with 218000km and the transmission has recently has overheated and failed. It no longer provides transaxle torque engagement, a common issue from what I understand.

(Funny story with that event - 200 km into trip to the cottage at 1am the trans let go. Next morning received a rental car, transmission goes on that too....)

I am now in the process of pulling the B7TA transmission and rebuilding it (adding cooler and filter). The transmission was originally replaced under warranty and I believe this unit has the oil jet added.
I was hoping some of you had the FSM (the transaxle section specifically).
Would anyone be able to give me a hand with this information? Any tips? I will be uploading pictures soon to show my progress. Thanks again.

Best regards,
Wiley

I think 02 (01?) through early 04 had the oil-jet add-on not the 4speed trannies. I've read that All-data is worth getting a subscription to for this work. There's a few threads listing tips, you just have to find them. Here's one.

Thanks, I'm not positive on the oil-jet; but I will find out when I crack it open. You are likely right saying its not in there. I have the transmission still on the K-frame waiting to be dropped. Rusted cat. converter has been holding me up.

Would ALLDATA be this for the Canadian version? https://estore.honda.com/service-express/subscription-details.asp?sku=H030CAN

I have read most threads for the four and five speed 3-shaft rebuilds. The videos on youtube have been useful as well.
Which of the valve-body kits would be best recommended (Transgo, Translab, or the Sonnex)?
Any info on rebuild kits? I can source ATP or Parts Authority the easiest.

I have a Spanish version of the 99-01 FSM which has all diagrams and torque specs, but my Spanish is very limited.
I was hoping someone could point me in the direction for an English version.

I used the Translab kit in my rebuild and I am very happy with how it works.
I assume you have done the research and have the special tools needed for this job?
Doing this job without certain tools can get very expensive.
My rebuild was on the 2003 5spd auto that I swapped into my 99 Ody. However the 4spd is very similar.
I got my manual off EBay as a download for $10.
It was a complete searchable PDF file for the 99 to 04 Ody.
This gives all appearances of being the factory repair manual the tech's world use.
The YouTube videos were extremely useful especially the 2 hour long one about the Honda tranny rebuild. It was not an Ody rebuild but was a very similar tranny and had a lot of good information.
He mentioned a set of tools called "bench buddies" that were very useful.
The biggest problem with these trannies s the shift valves sticking. He describes how to clean the valves and bores with these tools. I found them very useful and I do not think my build would have worked out so well if I had not managed to find them.

Good luck on the rebuild.

Thank you for the response.

What kind of special tools (minus the bench buddy set)? I don't have the main shaft holder or a clutch ring foot press. Would they be worth it?
Anything specific for special tools? What spec assembly lube did you use?

Any alternatives available in Canada to the bench buddy that you know of? I see they have a 1-800 number for Canada and borderline US states.
Might have to give them a call.

I've been religiously watching those teardown/rebuild videos and I'm okay on the assembly and nomenclature. The trans shop .pdf's like this are decent too http://www.jpat.co.uk/49 Honda 2B B7TA B7VA etc.pdf
Has your 1-2 response improved with the accumulator spring update? Translab seems to be my best option so far.
Thanks again.

The main shaft holder is a must have!!!
It has been tried without one several times but this usually results in damage and expensive parts replacements.
There are several large metric sockets needed as well.
You likely have some of these since you already have the tranny out.
I made several trips to the parts store trying to get the right size.
I found the bench buddy's at a local transmission supply warehouse.
When I contacted the people at bench buddy, they gave me the location of local retailers.
They are available in 2 size kits. A set of small brushes and a set of large brushes. I found the small set to work very well and did not need the large set.

I have a spare B7TA 4spd transmission that I am rebuilding for use when my existing one drops dead (original one with 200,000 miles and counting...). I have done the complete teardown on the spare and the only "special" tools I needed were an impact gun to remove the large nuts on the shafts (2 were left thread and 1 right thread), several size picks to remove the end plugs from the valve body, and a homemade clutch spring compressor (I used a piece of threaded rod, nuts, and pvc pipe fittings with a cutout to remove snapring). DO NOT use an impact gun during assembly anywhere! Adhere exactly to the torque specs for the various bolts especially for the valve body. An inch-pounds torque wrench is a must have! Hiram Gutierrez made some fantastic full-length videos on YouTube. Watch and re-watch them. Use the Bench Buddy's as mentioned previously. I have those too.

For a rebuild kit, here is a great example of what you need: B7YA B7TA B7VA TRANSMISSION REBUILD KIT W/ PISTONS STEELS & RAYBESTOS GPX FRICTIONS '99-'01 ODYSSEY & 3.2TL - The American Powertrain Warehouse
Whichever kit you get, make sure you get one with Raybestos GPX friction discs. They are the best and recommended by most trans shops. They are much better than OEM discs.

I am going to use the Superior Translab .388 valve body upgrade kit. It has the upgraded pressure regulator valve, 2 CPC valves, end plugs, and new springs. Here is the link: HONDA ACURA 6CYL 4-SPD AUTOMATIC TRANS VALVE BODY UPGRADE KIT: .388 CPC VALVES - The American Powertrain Warehouse

I am also going to get the Sonnax end plug kit for the valve body: HONDA & ACURA 4 & 5 SPEED O-RINGED END PLUG KIT: UNITS W/ DUAL LINEAR SOLENOIDS SONNAX 98892-01K - The American Powertrain Warehouse

Also, get a remanufactured torque converter. Never reuse your old one. I've seen them run from $110 to $250.

The biggest hassle for me was actually finding a cost effective way of cleaning the parts. I don't have a parts cleaner and I didn't want to spend lots of $$$ on cans of brake cleaner. I used gallon cans of mineral spirits. It cleaned well but was a pain to use and store. Cleanliness is very important in the rebuild. Don't forget to clean those shift solenoids and screens if you are reusing the old ones.

Finally, either get a FSM or a subscription online. It has everything you need to do the rebuild in detail. I can tell you that the transmission section is the largest of the entire manual. One more thing to consider while you have the transmission out and the subframe off... check your engine mounts. Now would be a great time to replace them and it would be easy.

Sounds like great information.
Hiram is the videos I was referring to as well.
I have wondered about mixing the different kits.
That looks like about the same rebuild kit I used.
I would use caution using an air gun to remove the nuts as well.
The problem can occur with the nuts spinning on the shaft as the air gun is prone to do.
How did you re-torque the nuts without the main shaft holder?

Thanks everyone. Parts have been ordered. Went with Translab and Raybestos. In my case Ebay had better pricing than RockAuto or similar source.

FYI I found the bench buddy to be a modified nylon gun bore cleaning tool. a 45 or 388 caliber bore would be similar in diameter, Amazon [CAN] had an okay selection.

Re-torquing the shaft nuts should be possible by engaging the park fork to prevent the shafts from spinning?

All in all, I'd say its been harder to get the transmission out than rebuilding it itself. Canadian winters have not been kind to the subframe and hardware.

Appreciate the info and help,
Wiley
