Got it. Thanks!

ive been doing 2days of research on this topic as i plan on picking up a 01 tl-p with a trash tranny. the wreckers in my area mostly have accord and odysseys so i will be picking up an 07 accord v6 5at. from the research ive done the transmission between the tl and the accord are 99% identical, the only difference noticed is the setup of the external filter, and that should not affect the compatibility

ill update if i can but wont make any promises

NVA-AV6 did this swap on my 01 Accord this past November.


Swapped out the J30A1 for a J35A3
Used a 7th Gen Accord 5speed A/T
03 Cl-s A/T ECU
5 speed A/T shifter w/ S/S mode

yes, S/S mode will work. I think you gotta wire it up a certain way. I'm not a wrench head, thus, thats why NVA-AV6 did all of it for me.

The tranny was a HONDA factory rebuilt w/ 17k miles. Filter and both pressure switches were replaced during the swap. It shifts hella better than my 4-speed.

Too bad NVA-AV6 isn't in TX... He'd be making some $$ from me. :-)

Same for me if he was in Indiana!

I am new to this transmission swap business. I have a 2003 TL Type S I am considering a 2005 TL transmission. According to the post all I have to change is the range sensor, oil/cooler, and possibly drive or tap two holes? I really want to keep this car, but I cannot deal with the infamous tranny problems. I have a mechanic that is willing to do the swap, but I have to give him all the info. Thank you in advance for your time and consideration.

Type-ES

The TL transmissions still had problems. not anywhere as bad but still had flaring.

the 06-07 accord transmission is the most desirable.

eric5582

With doin a 07 oddy trans swap in a 01 CL-s, What about harness length, connections, starter, trans mounts, VSA throttle body mounting, ect. Are these all extra issues beside the range switch and cooler?

Type-ES

I don't think you can use 07 oddy, only up to 06

tc5280

A hair off topic but I am going with the Level10 rebuild kit using the stock trans. Mixed reviews from what I have seen but hoping for the best. Trans is out now being rebuild so I will have some initial thoughts pretty soon

eric5582

Gotcha

eric5582

doin a 06 odyessy trans in my 01 cls, noticed that drivers side diff housing comes out about a .5" more and shift cable cover area is different as well. Are these issues anything to worry about?

02 TL

I was told by an Acura mechanic the 01-06 Mdx, 2gen TL's, Oddy up to 08, all have the same issues. Supposedly has to do with lack of lub disstribution in the tranny. Supposedly a cooler with a few hoses can be added to the tranny to correct the manufacturers f@*$k-up. I have a great mechanic in LI, NY that rebuilt mine for $1500 with a 1 year/12,000mi warranty. Only my second, but thought about a 6speed stick which I would prefer. Next time, I will go 6speed manual. Thanks for the info guys, very very helpful thread. I would like some more info on this. I'm thinking if these trannys are pretty much doomed for failure, only a matter of time, what about just doing an engine and tranny swap from a newer model? What later model Acura engine and tranny would be compatable with 2gen TL's? I'm def going to do my research. I'll start with my mechanic. I'll post results.

02 TL

hey tc5280, are those headlights retro fit? I've been working on a set of headlights, DIY project. Ordered projector lenses from an FX infiniti, made holes for the lenses but haven't attached them. Any advice? Housing is another concern. Any info would be great.

tc5280

Yeah they are, mini d2s though. I have heard the fx's are much harder to adjust correctly. I didn't actually do mine so check this thread out and it should give you some insight.

There are a few guys commenting on there that are advanced for sure. Get with tony3, mbp_tl and winhasse.

how much do 06-07 accord trans usually
go for

fast_eddie

My buddy just threw a 06 Oddy trans in my 02 TLS, so far its running nice and smooth. Its only been a few hundred miles, but it jus feels good to have my baby up and running. Oddy trans was almost half the price of AV6 or 3rd gen TL trans with similar milage.

So, I just picked up an 05 oddey trans for my 00 TL-P and im currently in the process of swaping out the trans fluid warmer and the range switch; everything looks good up to this point. As a note though, I did have to bypass the stupid power steering speed sensor lines.

Stephen00TL

^ anybody doing the swap in a base model tl will have to loop the power steering rack because there is no spot for the power steering speed sensor on the new transmission. It's just makes the steering a little bit firmer

EastBayTL

NVA AV6: Great info on this topic. Thank you. I'd like to run my scenario by you to be sure I have it right.

I have a 99 TL w/ a 4 speed automatic trans. I'm considering doing a total swap and installing an 03 TL-S engine and an 07 Accord 5 speed trans. If I understand this correctly, this will work as long as a I install the 03 TL-S ECU and engine harness, correct?

On a second topic, I see many state that if one is to go this far, I should just take the leap to the 6 speed manual trans. I personally don't want a manual trans, but I am interested to hear why it appears to be a "superior" mod that taps into more horsepower, etc.

Thanks in advance for sharing your knowledge. I'm wiling to spend the money to this, but want to make sure I do it right the first time.

Stephen00TL

6 speed swap is better because it is more reliable, better gear ratios and acceleration, it's is also about have the weight of the auto. I personally would rather shift the gears myself but that is a personal preference.

EastBayTL

Ok, so naturally I'm now intrigued. What is the best 6 speed manual trans to go with for the 6 speed manual trans swap?

Stephen00TL

The only one that will work is the 03 cls 6speed for certain. You can modify an 04-06 tl transmission to work but you would have to talk to nva av6 about that one. Your best bet to get a hold of him is to pm him

EastBayTL

Gracias amigo!

The manual is best for a couple reasons.

1. It doesnt have the problemmatic clutch packs that fail in the auto.
2. It (cls-6) has a LSD. It and by it self is worth its weight in gold
3. Its more efficient and actually gets more of the engines power the ground.
4. Its a few hundred lbs lighter, your car will like the lighter weight.


As for what trans works, Unless you are able to get your hands on the Richie Module you are stuck with the CL-S6 trans. It is the only one that will work with the CL ECU

Stephen00TL

Can't beleive I forgot about the transmission having LSD, as far as I know richie isnt making anymore harnesses unless something has changed

I just purchased an 06 Odyssey EX-L transmission . My car is at the Transmission shop and the owner is stating the transmission will not fit due to the Odyssey transmission being to big and whatever sensor is responsible for speed it totally different. I am sensing he does not know what he is talking about but just wanted to verify.

elproducto

I went to the transmission shop and saw what the owner was talking about. Basically the hole that the speed sensor goes into my transmission has a hole on top of where the AXLES go in, the new transmission does not have that hole. How did you guys overcome this issue or did your odyssey transmission have this hole. Pictures are below. The first picture is the B7WA transmission that came out of my 03 Acura TL-P with the speed sensor hole, the second is the BGRA transmission from the 05 Honda Odyssey EX-L.

elproducto

Okay I am answering my own question doing some research on this board, basically it was already talked about but I believe all that need to be done is to loop the power steering line and delete the speed sensor altogether.

elproducto

Just in case anyone was interested. The following picture is what the speed sensor looks like. This sensor will need to be deleted and the lines looped to accomodate the Odyssey Transmission.

Stephen00TL

I thought you were talking about somethig else. Yes you just loop the power steering rack and you get a little former steering wheel. I like it better on with the firmer steering.

elproducto

Correction that is not the speed sensor that is the Power Steering Sensor Assembly

Stephen00TL

That is what through me off when you were asking.

Do you guys think that wiring would be difficult if I try to swap a 05 Odyssey AT into my 01 Honda Odyssey? I need some insight. I have an 08 TL-S 6MT that I was planning on swapping into my Odyssey but It looks like the wiring would be a big issue for me. So I am either going to sell the 6MT I have or trade it for an 05 odyssey AT.

NVA-AV6

The 08 trans will not go, the bell housing as well as the solinoid layout is different. The 05 oddy trans will work, you just have to transfer the transmission sub harness and shift position switch, no real wiring changes involved.

Hello...
I just read threw this whole thread so i feel like i got a pretty good education, but would like to be sure i got my facts right as well one thing i don't believe i read about...

2003 TL type S - tranny slipped a tiny bit a few weeks ago when it was super cold outside, i took it to a oil change shop because it was due anyway, i had them check the trans fluid... They said it was a lil low and dirty so i should have it changed/flushed... Well it drove just fine so i took it 420 miles out of town for work, no problems at all... three days later when the job was done i get on the road home and it starts slipping really bad, a bunch of lights came on and what not... I have a Bluetooth scanner and the Torque app on my Note II so i check the code immediately... it showed as CEL #1750/1780 (IIRC) something to due with the shift solenoids... So i reset the ECU and clear the code then put it in reverse for maybe 3/5 feet... It seemed fine so i continued on my trip... I got maybe 20 miles before it did it again and this time all my gears acted like it was in neutral... No forward gears or reverse... I did a lil research and it seems that replacing or simply cleaning the shift solenoids should fix the problem... I started taking things apart so i can pull them off but it's been bitter cold, i only have one bolt for the t-stat housing to remove but again, it's been to cold... Plus i have my Accord wagon to drive so i haven't been to worried about it...

All that being said,
do you have any experience/knowledge about a simple clean or replacement of the shift solenoids fixing this issue..?

If i go ahead and go with the up to 06' Odyssey trany will i still have all the shift features of the type-s, of coarse after changing/swapping over the few parts you mentioned... (range switch, filter)

i realize if it is my shift solenoids i will want to get new ones for the Odyssey, if i have to go that route...

I hope i worded this correctly, and i really appreciate feedback...

did not mean to write a book lol

It appears as though you're in the midst of a big decision and attempting a last ditch effort to revive what may be a dying tranny. Ya have nothing to lose by cleaning the solenoid screens, but don't expect miracles at this point.

The best bolt-in replacement donor has been the '06>'07 Accord V6 tranny which has an improved design and appears to be proven more reliable than the original tranny's. Do some more research and start looking for a donor AV6.

4Door

^^^ not a last ditch effort by any means... the solenoids are really cheap to buy new, i will give them a try first soon as the weather warms back up... that wont be any time soon tho...

3.2TLc

Hey 4Door, did the slipping become worse after the oil change shop flushed the tranny ?
By the way you described things, ya may wanna start looking for a donor '06>'07 Accord V6 tranny !!!
