I'm so glad I did some further research on this issue and found this thread. I have a post titled something like "low growl at 12-1800 RPMs" that relates to this issue exactly. I'll be visiting my dealer soon to get this issue fixed.

I love this forum. So informative. Thanks for sharing.

I only have this "vibration noise/feel" when I drive from a stop then accelerate. I won't be drving like a granny or punching it like a race car driver, but it's just a little faster than normal driving. I don't have it at any other speed than off the line. I take it in thursday.

Thamac15

went to the dealer and had them drive it. They couldn't feel the vibration or hear the "grinding" noise. I then took a drive with the service manager and he couldn't hear or feel anything out of the ordinary. They were all very cooperative and respectful, no issues there. They looked at the engine and chasis, ran electrical test, no faults, no noticeable issues from the outside. Manager did say that if it gets noticeably louder or vibration gets harder then to bring it in asap. Told me that Acura hasn't issued any info/data on any related issue but made sure my visit was documented(i got a copy as well) in the computer and put it on their "watch for" list to see if any other peeps have the same type of complaint. they did happen to say that my car is the cleanest from the engine to the interior they have every seen. that made me feel good lol. so i'll just pay more attention to the issue if it gets louder ect.

Been a while since I posted. After replacing the A pipe, all was fine.. then 5 mos. later it came back. In October, 2011 the torque converter was replaced. NO MORE PROBLEMS.. car shifts better than it had for about a year.
I was the first at my dealer with this problem (grinding noise) but before I returned in Oct '11, they had already replaced another torque converter on a diff customer's car, so the problem was coming up. Obviously, the FWD vehicles do not have this prob, since they do not have a torque converter.

I hope this problem has been solved in the 2012's, as my lease is coming up and I am considering purchasing this time around.

ChuckyD

We both had this problem a while ago. They also replaced my torque converter AND replaced the entire transmission with one brand new off the line (showed me the tag that was strapped to the tranny). I'm a happy camper Advice to everyone else, reproduce the issue at will and make the tech ride with you. That's the only way...

Chalk up another 09 AWD for a torque converter replacement and the car acts smoother now in shifting. Glad it was under warranty.

JustinTL

hey, do you know how the wolf is doing when he wants to show his power??? he aint bark like a dog but hackles up before jumping in front and finish the enemy. so, TL is a wolf, some hackcles ( vibrate) at low rpm to show power, and finish the enemy by V-tec.

I took my '09 in this morning for the same issue and just received a call saying they have identified it as the torque converter. They have ordered the part and should have it in by tomorrow and I will be back in the car tomorrow afternoon, hopefully.

I look forward to the car shifting a bit more smoothly than it has previously.

I figured out why my gas pedal vibrates at around 1800rpm. My closed mechanic friend fixed it for me while doing the timing belt maintenance. He said it was something related to the fuel system. He cleaned it and now i barely feel the gas pedal vibration. I heard many Acura Tls will have some sort of fuel problem during its lifetime.

Edward'TLS

Gas pedal vibrates ???

Suddenly this force-feedback controller for the PS3 game console flashes across my mind.

The 4G TL is using the drive-by-wire throttle, and the gas pedal has no mechanical linkage to the engine body. If there is vibration, it's not being feedback from the engine.

JayTeeL

So glad I found this thread. I just got my TL about 2 months ago and have had this same issue. I've been trying to find time to take it back in. I'm sure it'll be a lot smoother process now that I have a lead on what the issue is. Thanks all!

JayTeeL

Took my TL in on Monday. Told them I believed the issue was the torque converter. Drove the car with a tech then the tech took the car to check it over. 45 min later I was told they were ordering a torque converter and they would call me when it is in. It is being replaced under warranty. Glad I was able to point the dealership in the right direction as I believe it saved a lot of time.

sdelia

Just got my '09 awd back from the dealer for this same issue, the converter was replaced and it is much better.
There is still a very slight vibration feeling if you are really looking for it, but under normal driving you would never feel it.
I just hope that this is the only time I'll have to replace the t/c in mine!

computecker

I think I have the same issue on my '09 SH-AWD. It is very annoying. I took it 2 times to 2 different dealers and made a test drive with a mechanic the 2 times. I was unable to reproduce the vibration/grinding the 2 times.

I'll try to put the problem on video and show it to the dealer.

Do you have any advice to reproduce the problem easily?

Anyone knows a good dealer in Québec with a good mechanic?

stars_fan

Any more info on what he did?

computecker

Recently I noticed that the symptom (vibration / grinding) was more frequent when I turn 90 degree on street corners by pressing lightly on the accelerator. Did you notice anything similar? Does it seem to be the torque converter? thank you

TSXV6Guy

FWIW, on my 2010 TSX V6, I am also experiencing this phenomenon. It appears to be related to the torque converter lock up. It was significantly improved after I replaced the transmission fluid with the new Honda DW-1 synthetic fluid. You guys may want to try this.

techdavid

my 2010 tl sh-awd is also at the dealer for this problem (also the sunroof rattle which the claim they fix by lubing the track), was told it is the torque converter problem. I just hope the Tech put every single nuts and bolts back on. Will have Vehicle back in a few days. My TL has only 35,000km

KarKraze

When you feel the vibration which gear are you in?

computecker

I'm not sure, I suppose the car is at the 3th gear. But the vibration is more like when you shift to 4th gear and the car should be in 2 or 3th gear with a MT. Is there a way to see the gear number on D like in S mode?

I will try to put this on video and post the link here. I presume this will be hard to hear it on video but at least I will try.

I have send an e-mail to 2 other dealers near my location to choose which one I will visit next time. I have asked them if they have replaced a torque converter on a 4th gen TL before. I have not received response yet.

KarKraze

Thank you for the reply,does the car shudder or vibrate like if you are driving over small rumble strips,also do you feel the vibration in the shifter.Sorry for all the questions but i have been reading this thread with intrest so that if i encounter the issue i would be well aware of what to look for.

computecker

There is a new (2012-08-21) TSB (# B12-029) that will correct our problem! We will receive a recall letter. They will update the transmission software and if the problem occur again they will replace the torque converter. The torque converter will receive an extended warranty of 8 years and 105K miles.

computecker

I have contacted a dealer yesterday and the TSB 12-029 is not published in Canada yet, only in the USA (I'm from Canada).

Does someone have access to the TSB for Canada?

Edward'TLS

Damn, I got rid of the 2G TL because it had a crappy tranny.

I'm always thinking that the 4G tranny would be bulletproof. I guess I was wrong.

Illuminati

Wait, so does this mean i can bring my car into the dealership again and mention this TSB and have them change it. I hate hearing this sound, i drive a little faster around the 30-45mph range so i can avoid hearing it, especially with someone else in the car.

Bobby39

Has anyone got the new software update for the torque converter? if so is the ride a lot better or not a major difference?

Hogan9166

iTrader: (1)

I don't think this is a software update. Most of those I've seen that have had this problem had their TC replaced. I have as well, and will need to do so again.

floridaseabee

We got ours updated late last week, took about 45 minutes. The shift points have changed and it seems to be smoother. We had our TC replace a while back, and hopefully this will prevent any futher damage, but I'm reading on here that the TC is covered by a longer warrenty now even if the factory runs out.

Ding34135

So it sounds like the grinding issue is likely the torque converter. I have an '05 TL and this phenomenon is new in just the last couple of months. What is the ultimate problem? Is a worn or defective torque converter cause engine damage or is this more of an annoyance? If the torque converter needs to be replaced, is it urgent that it be replaced to avoid worse problems?

TSXV6Guy

Try changing the transmission fluid to the new DW-1. I have the '10TSX v6 and this has significantly reduced the shudder.

osubigdog44

Just had this recall fixed on my 2010 TL SH-AWD. They updated the transmission software while I was in for an oil change. Only took about 45 min. Seems to have taken care of 99% of the problem. I was really trying to replicate the problem post fix and was only able to for a split second. Doubt anyone else would even notice but I was looking for it.

tfrankTL

I have read many posts about rattles while accelerating at low RPM and many saying that they fixed it, so mine experience might not be related to your problem. I spent the last 18 months crawling around under my 96 2.5TL, screwing in heat shields and adjusting exhaust hangers and nothing worked. I finally fixed the problem this weekend. I found the noise by driving on the highway to get the exhaust really hot, then stopping the car and crawling under before the rattle stopped. It was not a heat shield but the pipe itself between the cat and the rear wheel. It is a double walled pipe (who knew). I drilled a very small hole at the bend and ran a stainless sheetmetal screw through the outer pipe and into the inner pipe to pin it in place. No leak and no more rattle.

Alexns05

Have you guys figured out what the actual cure for this is? I've been experiencing some grinding/buzzing noise the past few days. It occurs only around the 20mph range, I'm not sure exactly what RPM. Probably close to 2000 rpm. It seems to happen before or after gear change but not during. I can feel a slight vibration in the gas pedal when this happens. Sound seems to be coming from the center engine (near the radio).

I'm hoping it's not the torque converter. If it is the torque converter, can I continue to drive with the tc going bad or do I need to get it fixed right away. And also how much does it cost to replace just the tc? I've got an 04 TL with 107k. Thanks!

C8N

Any updates on this?
I had my T/C replaced about a month ago and now I am experiencing this vibration.
I was able to replicate this with a tech on a test drive and the tech commented that this was not normal. The dealer had the car for two days but now they are saying this is normal. For me, I know this is not normal since my car did not do this prior the T/C replacement.

C8N

I posted my issue on another automotive forum and someone suggested it might a clutch shudder? Any thoughts on this?

Ok I just bought my acura tlx 2015 in January 2015. It's fwd. This is unbelievable!!! Brand spanking new car and I am at acura in hertrich New Castle, DE service dept getting this checked out now. I had my mom's 2000 acura mdx and it had the same problem. After it got really bad i got it checked out at Price acura dover, De they said it was the torque converter. And now with my tlx I'm having the same problem, except atm it is very subtle. since it's within warranty I hope they know what they r looking for. Will update after they check out to let yall know. Same exact descriptions as everyone here and it's happening on an 2015 ACURA TLX, totally unbelievable
