Just finished this project. I've only had it out for a few miles but I'm definately impressed. Smooth crisp shifts and no whine that has plagued me for the last 170k.

The donor was an 07 accord with 54k that I snagged for $1,100.

quick question:

Do I grind out the ribs inside the new range selector cover to make it fit?

Thanks to all!

Iggy

SuperGreg

Same here! That stupid whine is gone. My brother did the range switch cover so I didn't see exactly what he did, but basically he took some angle cutters and just snipped away any bits of the cover that got in the way so it would fit.

Thanks SuperGreg. I felt really stupid after posting about the neutral switch because despite searching for an hour for an answer I didn't look at the end of this thread where it was described. And you didn't flame me which was very nice.

I just noticed one of the solenoids had it's sensor broken off on the Accord trans and the one for the TL is still good. I checked and the part numbers are the same but I don't know if it's likely to be contaminated and shouldn't be used. Any input would be appreciated.

I will also be sure to post up when I get it started and updates on how many miles I get out of it so that everyone has one more data point. Thanks for everything y'all

Skirmich

^^ Mine also had one sensor broken and I just swapped from my TL without bothering to check for numbers..
They looked identical and it worked flawlessly.

TensorWorld

Okay, update for anyone who want's another data point. Got everything in, filled up the trans, turned it on and it started right up and had no CEL or anything. I was kind of amazed. Then I took it for a drive and one of the CV axles popped out cause I didn't push it all the way in. Fixed that and did a 3x3 change and it seems to run like new. I've bled the brakes and fixing to get it ready this weekend to go for a test drive on the freeway and check high speed but it seems to be just as easy as it's described on here. Didn't even have to adjust the neutral switch. Thank you for this swap DIY and good luck to everyone else.

SuperGreg

Nice, congrats!

Resurrecting this old thread, I have a 03 TL with low miles thats not going to 3rd gear. Already tried the basics, fluid change 3x, replace tranny filter, clean solenoids & screens, etc. It didnt help

I noticed in this thread all its talked about is 06-07 Accord V6 tranny swap.

My question is will a 2005 Accord V6 tranny work? I can get one considerably cheaper locally rather than ordering elsewhere.

Appreciate an answer.

MarcDavidoff

No sir- only 06/07 V6 non-hybrid

WheelD

any reason why not 2003-2005 Accord V6?

Skirmich

Too close to the same years with defective units, They are running the Blue Bolt transmissions which are the old 3 shaft trans but with a band aid..
06 and 07 are Running the latest 4 shaft design of the 5 speed in comparison.

WheelD

Ah I see, appreciate the replies.

well this 05 v6 Accord tranny came out of a wrecked car with 94k miles, for $200 I might take a chance , can't be any worse than my non working TL tranny right?

SuperGreg

I don't think the 4-shaft was introduced until 2008 for the Accord (2006 for the hybrid model, which we can't use), and as far as I know differs in the solenoids and sensors/etc and is not compatible with our ECU.

BAYA, three shaft (main, counter, secondary) spans 2003-2007. We assume the later years, 2006-2007 have the bugs worked out.

B79A, four shaft (main, counter, secondary, third) 2008
http://www.makcotransmissionparts.co...g-pdf/BDHA.pdf

Please correct me if I'm wrong, but I don't see how the 4 shaft would be a direct bolt-on.

SuperGreg

I think it depends on how easily you can DIY the job. If you are paying someone to do it, it would make sense to find a newer unit. If you can bang it out in your garage without too much trouble, it's a cheap option that might last a while. Probably would be a good idea to get a new torque converter with the miles on that tranny (get the one for the Accord, not the TL). Just be prepared to replace again.

Kris9884

I read the first several pages but didn't see anything about it. Is there a way around losing the easy fluid steering after the swap? Like, can I ground the sensor or trick it with a solenoid or something? I already have a sports car, I'd rather not have to strong arm the wheel on the comfy daily. Or is it exaggerated and not that bad?

WheelD

yea definitely doing it myself in the garage and dont plan to keep it too long just trying to keep the car for the winter then will be selling it in the spring/summer next year

Skirmich

I cant say either, I was under the impression the 06-07 had the 4 shaft design.

Kris9884

Drunk driving lol, nice...

But anyway, why does everyone tell the shop its from a different car and scare them off like its a custom one off job? If it's a bolt-on affair they'll never know. It's your own fault for telling them its from a different car and having them turn you away. Just my .02

WheelD

so got the 05 AV6 tranny swapped in, BAYA transmission. Used the Accord torque converter and all, bolted up fine except one small problem. Torque converter bolt holes are off to the TL engine flex plate, looks like the torque converter is physically smaller. I can just see the edge of torque converter threaded holes through the flex plate but they arent lining up fine. I know the torque converter seated in fine.

I should have measured before installing it, now tranny has to come out again.

Anyone else experience this?

thoiboi

Every FAQ I've read says to use the 06-07 transmission. You took a risk using the 05. Aby reason why?

WheelD

it was $200 and only planning to keep the car until may

SuperGreg

I had a weird situation where I thought the holes didn't line up at first when I first got the tranny in, I have no idea what was going on but after rotating the flex plate and torque converter around a bit I found that the holes did line up fine.

Could you post a pic?

WheelD

yeah i've been rotating both as well but it won't line up

see 2 pics

Iggy

That's certainly not a small problem. wonder if an 05 accord flex plate would bolt onto the crank or if an 06-07 TQ will work in that tranny

WheelD

I know its not recommended when using AV6 Tranny but should I just throw on the old TL torque converter onto the AV6 tranny to get rid of this problem?

SuperGreg

Someone posted before that using the TL's TC will not work, due to some part mismatch but I don't remember the details. I'm really surprised at the issue, you would think somebody would have run into this by now.

WheelD

wonder if 03-05 AV6 transmissions had different torque converters vs 06-07 that's why nobody else has had this problem..

WheelD

to answer my own question I pulled the tranny out again and compared the AV6 torque converter to the TL one, it IS smaller than the TL one! So if anyone is else trying to do swap in a 03-05 AV6 tranny like I am because it was so cheap, you will run into this. Not an issue with 06-07 AV6 transmissions though.

I will try to run it with my TL torque converter and see what happens. I attached the tranny back to the engine and got the subframe back in place. Tomorrow I will try to have rest of the parts back on to see what happens.

this is not my main car and I would not recommend doing what I am doing if you are trying to fix your main car, I am just kind of having fun with it and seeing if I can make it work.

Skirmich

DO NOT DO THIS... As noted from another Ziner the AV6 TC is smaller in depth so the Transmission Bell Housing is smaller in consequence..
Using the TL TC will fit but will press against the Bell Housing and input shaft, Starting the car with that setup will destroy the transmission bell housing.

The 06-07 AV6 TC should fit no problem, I bought a Remano unit (2007) and it bolted right in no problem.. Looking at both TCs side by side you should see the size difference and why the TL unit should not be installed in the AV6.

WheelD

Replying to your "TL TC will fit but will press against the Bell Housing and input shaft," if that is the case, shouldnt I hear a rubbing noise? I mean I spun the engine over several times by hand after the install and did not hear any noise where the torque converter is interfering with anything nor was the engine difficult to spin as if there was any interference anywhere..

Skirmich

How did the TC spin without being bolted to the flexplate? or You mean the TL TC in the AV6? Beats me, I did it the right way! So I dunno exactly how it gets damaged:
You should go back a couple of pages and look for the Aziner reply, He even posted pictures of the damage.. If it isn't here its in another of the AV6 Swap Threads..

WheelD

When I added the TL TC to the 05 AV6 tranny it spun fine, didn't make contact with anything. Even when I joined the AV6 tranny back to the engine it still spun fine.

What it appears is that 03-05 AV6 is different than 06-07, in which the TLs TC will cause damage. I didn't get a chance to work on it today but so far I don't see it damaging anything

WheelD

I wanted to update everyone and to say that I have successfully completed this project. The car shifts so smooth now there is no comparison to the old TL tranny. I want to thank all of you for answering my questions and all the resources this forum offers.

To sum it all up this is what I am using:

- 2005 Accord V6 BAYA transmission
- 03 TL torque converter
- 03 TL wiring harness swapped over
- 03 TL transmission filter swapped over
- currently running Valvoline Synthetic MAXLIFE ATF

SuperGreg

Great! Good job man.

Hello,
I located and purchased a 2006 Honda Accord AV6 auto transmission; my 2003 Acura TL with 138k transmission just started to slip and exhibit all the problems this forum pointed out.
I purchased the Acura from Rosenthal Acura Gaithersburg Maryland for my son last May with 135k and I was assured the transmission was updated; well -- . . .

I have my local shop in Frederick Maryland preparing for the install;

1. I am printing the instructions
2. I am reviewing the parts I need to order or have my shop order -- can I verify these parts?
3. Asking my shop to order a new honda accord AV6 TC and take care of the core deposit

Anything else???

SuperGreg

Check "what do I need" section here for a pretty full list: Havener Garage: The Definitive 2nd Gen Acura TL AV6 Transmission Swap Guide

WheelD

yes that is a very good guide. But before you begin ordering anything go back to the Acura dealership where you purchased the car the year before and see if they will do anything for your since they did say the transmission was "updated."

vmdigioia

Okay -- I have a hold on the transmission --

These are the codes from the car: P1750 p0505 p1298 (D5 is flashing with the other check engine light on and the TCS light on).

I spoke to Rosenthal Acura -- it is a joke -- no warranty, -- I looked at the bolts on the transmission -- they are not 'blue' -- I asked for a mechanics report -- this is a one owner car -- no help from Rosenthal at all.

WheelD

I hate dealerships like that, it seems you are pretty much on your own. Only one of your codes is transmission related, which, if you are lucky, could just be a dirty solenoid screen.

Other one is idle control issue? Is the car running rough? Last code is concerning your electric charging system, could be a short somewhere or blown fuse? Kind of weird having all these 3 different codes at once, might be something related.

Willis801

Just picked up my 07 accord trans and i have a question is it necessary to swap the heater on top of the trans to the accord because in one write up it says yes and in the havenergarage instructions it says nothing about the heater being swapped? Thanks
