Back again after several months!

Ok, I completely rebuilt the transmission myself finishing it last August. now, mind you as i have a second car, I worked on it sporadically so forgive my not replying sooner.

The cost to rebuild was $487; New clutches/steels kit with all gaskets, rebuilt converter fluid and the replacement 2nd clutch piston assy. (plus a few parts that broke while dismantling)

Video'd the entire disassembly and re-assembly which helped out as I forgot how some things were installed and the shop manual wasn't too clear.

At 255k miles now and still runs great. Keeping the DW-1 fluid in.

Not to thread jack but would some one be able to tell me where the trans/vehicle speed sensor is located? I have 06 Accord V6 auto. Thanx.

This unit uses two sensors of the same type, off the top of my head, here are the generic loacations.

Thanks!!!

Its ALWAYS cheaper to do it yourself. Is the repair good enough to last another 240k miles? Time will tell.....



Good job anyway.

I uploaded the video of the disassembly/re-assembly to my youtube channel to be used for reference here!

Is this the k24? I'm assuming it is since J autos never ever ever last that long.

The story once again....


My 2006 Honda Accord V6 Transmission Rebuild: BAYA Style!


So back in February, 2013, I was driving the sporty Accord home after a productive day at my job. As I cruised to a speed of 40 MPH a loud BOOOM came from the engine area, and subsequently, the car's front wheels locked-up, literally! I found myself on a semi-busy street nearly being slammed into by an approaching Ford F-350. I was in disbelief momentarily..."Did I just break my baby?...Did I hit a deer?"

After a day I was able to take a look and discovered the car ONLY moved forward and ONLY in Neutral position on gear-shift and never shifted into second gear. Now, thinking a transmission is a task I do not wish to undertake, I elect to drive it (going only 20 MPH as this was all first gear allowed) to Superstition Springs Honda in Mesa, AZ. The Service Advisor, Petr, said he would have his wrench monkey have a look at it and also replace the Power Steering hose which was a recall issue a few years ago. ( I had already replaced the hose myself, but Honda Corporate denied reimbursement as it was not initially done by one of their Service Centers). After 2 days, Petr notifies me that my car has suffered "Catastrophic Internal Transmission Failure" (well..no s&*%!?!) In short, he said he would speak with our good ol' friends at Honda Corporate to inquire about any good-faith repair work that may be possible as the Accord transmissions were notorious for failures of this magnitude. He came back with a displeasing answer, but not unexpected. Given the 244,000 miles on the car, Honda declined any assistance with repair...which I was OK with! But what he said next is what really pissed me off!! He informed me that Honda would drop in a REBUILT transmission with 3 year/36K mile warranty to the tune of $5200. I almost fell over with laughter! "..Hell, I could put $5200 down on a Nissan 350Z.." We both looked at each other in amazement and I returned to my car and drove off the lot...at 20 MPH.

Over the next few days, I gathered some quotes to have the unit rebuilt, replaced or to accomplish the task myself! And here are the results in brief: Rebuilt and installed-1 yr warranty= $2800; Used Transmission with 100k miles= $1195; Rebuild myself= $527 +labor+knowledge!

SO, yes, I decided to rebuild it myself. Already had the service manual and the V6 supplemental from Helm, 300 gallon Craftsman Pro Series compressor, Air Tools, hydraulic jacks, etc...plus the help of my break-taking buddy. I had done plenty of research in the manual, looking at exploded diagrams from hondapartsunlimited.com, makcotransmissionparts.com; information from wittransmissions.com, YOUTube, specifially this video by Hiram Gutierrez and valuable information from Bob over at Parts Authority in Mesa, AZ (partsauthority.com)

Hardest part about the removal was not completely removing the sub-frame in the front end and having to maneuver the transmission over it with a rolling jack. Disassembly took place over the course of 3 weeks. I took my time and marked and bagged every part, bolt/hardware associated with it and video taped each step for reference upon re-assembly (this actually proved valuable!) Once the unit was completely disassembled, each part was immersed in solvent for hours, dried and blown with compressed air. I then utilized a micrometer and vernier caliper to measure the steels, thrust washers and other tolerance-precise components. This was important as comparing the old parts to the new replacement parts was critical to the 1/1000th of an inch.

I discovered the culprit of the well-phrased "Catastrophic Internal Transmission Failure"—The low-hold clutch frictions and steels had become so hot that they literally melted and were fused together (sic). Aside from the burned clutch basket and slightly burned 1st clutch assembly, the rest of the transmission was in good shape.

Upon seperating the transmission case from the torque converter housing, I managed to bend the shaft arm ($32) and snap the detent arm ($28)

I was confident enough to change my own timing belt, and adjust the valves, but I think this is over my head. The thought of installing the transmission after doing all that work, and finding that I screwed some little thing up and have to do it all over again, is enough to keep me from even trying. Congrats to you, for having the guts to even try.

Ah you forgot to put 3 weeks of down time here.Many people cannot be with out their car for 3 weeks. What kind of monetary value is 3 weeks of your time worth? Anyhow, kudos to you for doing it.

I would've had it done in 2 days tops,but I would've charged 2 grand for that,LoL!

Kudos to you for making that repair successfully on your own. SS Honda was my Honda for quite some time. When my tranny started to go on my '04 6MT Accord, they quoted me $6,000 (clutch needed to be replaced as well). I took it to Precision Fleet in Tempe, and they did it for $3,400. I would have loved to do the repair on my own, but I just couldn't have my car out of commission for as long as it would have taken me to figure everything out.

my 98 v6 just ate the tranny as well. I suspect Torque Converter failure as well. No power applied to the wheels until 1800-2000 rpm

I realized this is an old post, but just wanted to give some props to all who contributed!

Was planning to rebuild mine, but never tackled a front-wheel drive unit before. Thank you for the great videos and comments by all!!

Best,
Bill
