I haven't reset the ECU since I figured it will come back on, beside what's the odd you think it might stay off? since it triggered the lights which I'm pretty sure it might trigger again...

After the lights came on I just drove home and parked... haven't drive since, I'll bring it to shop tomorrow

Skirmich

Because if it isn't failing and the TQ its doing its job then it doesn't make any sense that its still poping the code..


Resetting the ECU might trigger a different one or might not trigger anything at all. By itself the ECU resets itself in a couple of hours running without any issue and it will turn off the MIL...


P0740 is faulty T/Q Clutch Solenoid but yours is working OK so why its ON?....

went out did a test, took the clock fuse out and reset the engine light, drove on highways... once past 60MPH for few sec then all lights came on. pop my friend's scanner in with P0740 again

Skirmich

Then it only pops when its trying to engage the T/Q at highway speeds... You need to check if its indeed engaging it doesn't make sense its throwing a T/Q Solenoid Code if its working OK.. At 60MPH with T/Q Engaged your RPMs should be in the 1500 area... when you step down half of the accelerator it should disengage and go up to 2000+RPM... This will tell you if its indeed working.

jzhu625

I can tell the T/Q is working since when I step a bit more gas on highway the RPM does move higher.
I just dropped off this morning and will call them in early afternoon. keep everyone posted!

I had the same failure code. After I researched this site I decided to do a D&R and prepare for my transmission to die.. I had the same exact symptoms Christmas lights at 60 mph. The transmission completely failed about 2 to 3 weeks later it was very slow to engage all gears and was flaring between shifts. It eventually wouldn't budge. Swap in the AV6 the rest is history. Sounds like the shop has some "xplaining to do". I hope you get this all worked out.

I hope they didn't put a broken Accord transmission on it when I agreed no warranty. if that's the case I'll take them to court, they gave me a receipt stated BAYA transmission on 2002 TL with 12 Months warranty.

Could be a worn convertor, or possibly a malfunctioning solenoid ?

jzhu625

iTrader: (2)

called the shop, they said they're working on it, i'll stop by shop and see what they're working on.

jzhu625

iTrader: (2)

Update: stopped by the shop and the car was ready, they said they replaced the solenoid sensor, so I took the car for a spin...
This time the car feel like a bit hard to downshift when I step a bit more on gas. anyhow, moving forward, after the car reach 60MPH for like few sec then all lights came back on. so I dropped back off to the shop.

Memphlow

Ask them about the Torque Converter and fluid level and type.

VTEC11

It's TL-P, prefer a shop and I can probably locate an AV6 online somewhere. What did you have in mind?

jzhu625

iTrader: (2)

UPDATE: So I picked up the car and they told me they replaced brand new solenoid sensor and the car is perfectly fine. shift fine and drive perfect!

Question for people that did the accord tranny, is below RPM correct? I'm on 60MPH and my RPM is at 2k

Skirmich

^^ Is that a constant speed or pick up??
Cuz I do a lot of highway speed and I'm absolutely sure you should be riding 1.5K @60mph and 2K at 70mph 2.5K at 80mph < I care for my MPG that much...
By the looks of it you don't have the 500RPM threshold of the TQ Convertor clutch system.


So unless you were picking up speed the RPM is obviously off, Looks like TQ isn't engaged..
Engage Cruise Control in D5 at 60MPH on flat ground and your RPM should stay at 1500RPM..

I have found a used 2007 Honda V6 tranny that I'm going to install in my 2003 TL Type S... can anyone tell me what the part number is for the tranny's main rear seal ?

jzhu625

iTrader: (2)

above is the RPM @ 2K with 60MPH constant when I'm holding the gas on highway. i think by time i get to 70mph my RPM should be at 2.5k. if my TQ convertor is not engaged.. you think engine light will come on?

666wokker

2k at 60 is normal, remember the av6 trans has a shorter 4th and 5th gear

3.2TLc

Yeah, as 666Wokker said about the AV6 gearing.
The RPM's on the donor AV6 seem to run a bit higher than the original trannys at the same speed.

jzhu625

Thanks guys! phew. Accord tranny on my TL. woot woot!

Here's my review so far...
It does drive good and shift from 1st gear to 2nd gear which a lot smoother but from 2nd to 3rd not that smooth but still great. overall on highway when I need to speed up the car did not need to downshift which it's a plus, i like the power in same gear.

BoriTL

anyone anyone??? any 99er done the swap

jzhu625

iTrader: (2)

UPDATE: all lights came on AGAIN. will bring car back to them on Monday

Skirmich

FYI: TL-S and AV6 Trans have EXACTLY the Same gearing..
Only TL-p Transmission should see a different rating


So I can compare my TL-S transmission and AV6 equally.
1.5K for 60MPH is the Normal for Cruise driving..
Bear in Mind I do 80% Highway with my TL So I'm pretty OCD with these things.


His TQ Isn't engaging...



Yah had to happend those 500RPMs where all my Hint... Got the Codes? P0740 again?

jzhu625

iTrader: (2)

I haven't get a chance to scan the code yet, I'm planning just bring it in and let them take care of it. I'm thinking to tell them just put the Acura transmission back. it's getting annoying....

Skirmich

^ Seems weird you are having this problem as your not the first to do the swap I haven't seen that issue so many times in any other thread... Seems they are doing something wrong.


I would not advice you to put your old one back.. That code isn't in any scenario a Swap Killer and you are getting it constant so its your only issue left.

Memphlow

Have you asked them how they handled the torque converter with the latest transmission? Is it new or is it the same one from the last TL transmission that failed??? It is the only possible common link from the one swap to the next since they tested the sensors. If you don't bring it up they probably won't either since it involves dropping the transmission again. I've thrown this out there a couple of times..

jzhu625

iTrader: (2)

update: so i gave up with accord transmission, either they don't know how to make it work or just my luck. either way I'm done with going back to shop... it's annoying.

JDM_DoMo87

Hey what's up guys,
So I'm reading on this article and really want to get this av6 transmission. My car currently has 178,000+ and my transmission slips and shift super hard. Then after awhile it won't go over 20mph. I live in nyc so where can I get this transmission at and where can I get this job done.

3.2TLc

Hey JDM_DoMo87, you can try the "Regions" sub-forum for other members in your local vicinity. Living in NYC, you should have several shops who could possibly do the "AV6" donor replacement installation for your TL's old ailing tranny. Check with friends, neighbors, yellow pages, etc.

When you talk to the shops, simply ask them if they would be willing to bolt-in a direct replacement for your sick tranny. Don't tell them that it's a swap. Start looking for a donor "AV6" tranny, which is an updated version of our original 5 speed AT. This "AV6" will come from a '06>'07 Honda Accord V-6 model. Figure less than $1000 for the tranny and about $500 labor to install it.

JDM_DoMo87

Thanks tlc3.2 I will try... hopefully I come back with good news

3.2TLc

^^^ Also, when looking for a donor AV6 ....... check some of the local auto salvage recycler's.
These guys have connections, and may be able to do the installation or refer you to someone who could.
Good luck in your search !!!

TLZINE99

Also make sure to ask the shop if they have previously worked on or have good knowledge/experience working with Hondas and Acura Transmissions.

03blackbeast

I think this is a moot point since the swap is so easy. I took mine to a redneck shop in downtown Indy out here and they didn't even know what an Acura was. They got it when I told them it was a Honda. They'd obviously never worked on one. Swap turned out fine thanks to the diagrams and info I found and put on here along with everyone else. Swap is simple just make sure the shop has done tranny's but they don't necessarily need experience with Honda's.

kelvllv

update - it has been 20k miles since the swap and my car has been running great. if anyone around the bay area is looking for a shop then feel free to pm me at a great price

jdmitr03

So today I finally received the bad news about my 02 Acura TL's transmission (130k mi) :c .. Apparently it is starting to show signs of the trans. wearing out, and the shop recommended I go ahead and rebuilt it now before I get stuck on the road somewhere.

At this point I'm not sure if I want to rebuild or go ahead and try this swap out. The owner tried to convince me that rebuilding is just as good if not better since I'll have new parts installed. I got quoted $1400 for a full rebuild including labor of course.

What do you guys think I should do? I don't really want to read through this whole thread, but to those that didn't opt to rebuilding and opted to go this direction instead, was it worth? No offense to jzhu625, but that is exactly what I want to avoid, is having issued afterwards and having to take the car back to the shop. Ain't nobody got time for that.

03blackbeast

You can drop an AV6 tranny in for about the same price if not less if you're careful. The AV6 has an updated design and allows better flow to your gears which is why your current tranny is having problems. If you want to avoid future recurrent problems, go with AV6. I'm at over 5,000 miles now on mine and it's as strong as an ox. Highly, highly, highly recommend it to anyone I see. It's worth every penny.

3.2TLc

Hey Jdmitr03, what are the actual problems which you're presently experiencing ?
~Has the tranny been ever replaced before ?
~Has the fluid been replaced ?
~Are there any CEL codes or flashing "D5" ?
~Have the motor mounts been checked ?

IMO, I'd get a second evaluation of the tranny, if uncertain of it's condition. Don't feel pressured to have work done unless you're certain that there's a seroius problem. The $1400 quote seems reasonable, but is the shop experienced with Honda tranny's and what is their warranty on the rebuild ?

jdmitr03

I didn't bother to ask about the warranty because I told him I was not ready to spend that much on the car right now for repairs. The car is in the shop getting the oil pump seal replaced due to an oil leak I've had issues with for a few months now. And yes, they are experienced with Honda transmissions. I forgot to mention that he did say he estimates the car is still drivable another 8-12 months before it goes or gets worse.

3.2TLc

If the tranny shop told ya that the car is still "driveable" for another year, than just drive it.......or sell it !!!
But seriously, don't rush into things until you're sure that the tranny is actually going bad. In the meantime, study your options....check out the "AV6" threads for the newer design '06-'07 Honda Accord V-6 tranny as an alternative to rebuilding the original tranny.

TLZINE99

Fluid changes is what u have to worry 4 now.

3.2TLc

Recheck all of the mounts. They can cause tranny jerks. Cheaper to replace than tranny.


Some things to possibly help keep your "iffy" tranny going for another year:
~Do a drain & fill using only Honda DW1 fluid.
~Check the pan's drain plug magnet for residual fines.
~Have a sample of the fluid evaluated.
~Replace the spin-on AT filter.
~Clean the solenoid screens.
