Hello all -
We went to dealer and they checked out transmission under the recall - they told wife tranny was in good shape when they looked at it.
We had been and still have a problem we can reproduce. Scenerio - Traveling at approximately 20 mph , with VERY slight acceleration the X's starts stuttering.
It is barely noticeable, it kinda feels like drivin over a gentle washboard road or when you are barely lugging a manual transmission.
My guess is that it is having hard time determining what gear to be in or just having slippage.
The dealer mech's said they could not reproduce and therefore saw nothing wrong.
HAs anyone else had similar situation?
Many Thanks,
DON |

There are a couple of posts similar to this from '03 owners. The comments were that the car sounded like it was going over rumble strips at certain shift points. It happened on our '03 twice, for only about two seconds. If it gets more regular, I will probably take it in for a once over.
If yours is an '01 or '02 (per your comments on the recall), it may be a different issue as it is a different transmission. |

Don.. ours does the same exact thing. It started maybe a month or so ago (around 37k miles I think). Since then it's had the transmission recall and checked out okay. I mentioned it to them when dropping it off but picked it up on a Saturday when they're closed so didn't get to speak to the technician at all.
I'm going to make sure they note it in our service records that it's happening just in case we have a warranty issue later on. |

I don't think I've seen anything that definitely says what's different on the transmissions across model years? Are the 03/04s in fact a completely different transmission design? Or are they basically the same with maybe a small factory installed modification for the 2nd gear flow problem? That's my guess but maybe someone knows for sure.
I ask because I've been considering a new Honda Accord or Acura TSX/TL and I'm a little gun shy since the whole tranny issue popped up. I'd like to see Honda announce a new and improved tranny design. Maybe a CVT type tranny like Audi has? I don't know much about trannys but I don't like the feeling of mine slipping in the X or the thought of having to shell out big bucks to replace it if it's no longer covered under warranty when it finally blows.
Thanks in advance for replies ! |

Hey Jude - IMHO - I wouldnt let the issue keep me from buying a Hoda/Acura because they seem to fix problems unlike others.
I would buy a Manual Transmission from them if I had a choice.
We are the orginal owners of an '88 Integra with 240,000 miles and i will tell you that car is bullet proof in all areas but the A/C which is a peice of crap.
The insnt going to be a big difference between 01-02 trannys
and 03-04 excpet maybe that oil jet fix, or something like it.
They would never "completely redesign" these trannys - cost too much. You keep what is peices of proven technology and build on that.
My wife had them replaced my EGR valve today - If I still have problem, I will push for new aka rebuilt tranny. |

Keep us posted on if the EGR valve (whatever the heck that is) does the trick on the shudder !!
I'll probably go ahead with the purchase of an '05 Accord/tsx/tl regardless of the transmission questions but I'd feel better with some reassurance that it's not going to go bad in the first few years!
I do think the manuals have fewer problems but I'm not going to fight with the wife over it and automatics are definitely convenient for commuting...which is what I'll be using the new car for mostly anyways.
Kind of miss the manual of my 88 Prelude I had years ago. That was one fantastic car. (wonder where it is today?? probably in atlanta somewhere as that's where i lived when i sold it) |

Most likely it is the EGR valve. The dealer in my area replaced min ans a few others with the same problem.
All is good, my X drives like new again. It wasn't the tranny, although it sure felt like it.

| I have the same stuttering symptoms for a couple of seconds when I accelerate past 20 miles per hour. (happened again tonight) It has happened a few times in the last few months on my '01 MDX with 62k miles. It shouldn't be the EGR valve because I had that replaced at 53k miles when one of the warning lights came on and stayed on. And I had the oil jet put in as part of the tranny recall just this week. I will keep an eye on it and feeling better that I bought the extended warranty. |

:( EGR valved replaced - NO FIXEY problem. Oh well.
Will be going back to dealer. |

| can someone explain what the EGR is? MY X is having this studdering problem when I am at 1500 rpm. |
|

EGR stands for Exhaust Gas Recirculation. The valve recirculates gases back into the combustion chamber for reburning. It is an emission control item.
If the valve is not operating properly, it can get stuck open and cause the engine to misfire. That is why it appears to be a transmission problem. |

There is a transmission shudder that will feel like what you guys are describing, very light accel, usually around 35- 45mph.
You may be able to hear a flutter type noise when you feel it shudder. This is from the torque convertor at lockup. The tech needs to drive it under the exact conditions in order to duplicate the problem. |
|
|
| Hey-Jude |
hey living... so if they can replicate it and it is something to do with the torque converter.... is that what needs to be repaired/replaced? Or is that still more of a transmission issue?
i'm just trying to understand from what you said if the torque converter itself is the problem or if it's just what's causing these symptoms but the transmission is what's really bad?
did that make sense?
has anyone had the torque converter fixed and found that fixed these problems?
Thanks! |

| Definition: The EGR valve is the main emissions control component in the exhaust gas recirculation system. The valve is located on the intake manifold, and opens a small passageway between the exhaust and intake manifold to allow a metered amount of exhaust to flow back into the engine. This reduces combustion temperatures and helps control the formation of oxides of nitrogen. The EGR valve is opened by the application of vacuum to its control diaphragm. Some also require a certain amount of exhaust back pressure before they'll open. On newer vehicles, the valve is electronic and uses one or more solenoids or a small stepper motor. The valve should remain closed while the engine is cold and at idle. It should only open once the engine has warmed up and is running at part-throttle. If the valve sticks shut (or is disconnected), NOX emissions will soar and detonation will often result (See Detonation and Spark Knock). If it sticks in the open position or fails to close all the way, it acts like a vacuum leak resulting in a rough idle, hesitation and possible stalling. |

Have same problem here- 82k on the odo now, but started at 68k
or less. Have been back to the dealer now about 5 times over a 6 month period. Shuddering like going over rumble strips at very low rpm (right after upshift) with little or no acceleration.
First 3 times, dealer couldn't replicate.
Then, felt it briefly for a second.
Then got oil jet bulletin, and put that in. Didn't help.
Brought it back again with Engine light on and VTM4 light on, and they put in a new EGR valve. Didn't help.
Last week, I dropped off the car to have them drive it for a day and night, just to get them to notice it again.
They got it to happen once or twice. Told me they don't service
transmissions, but it probably needed a new one. They said I could try replacing the gear sensors (about $600 for the parts and labor),
but it was a shot in the dark since they don't do tranny servicing.
Dealer told me to try going to the Tranny place they get their tranny's worked on.
Went to the tranny repair shop. They took it on a test drive and
put it in the air for a look underneath (initial look only). Said they
noticed AT fluid black like mud, probably never replaced (although we get the car serviced per schedule from Acura (going to find out about this from the dealer)), and that the hydraulic engine mount
is bad (leaking, no fluid left). They suggested a pressure fluid exchange ($200-300) and replace the mount, as first steps before correal expensive internal work. The tranny place did mention that it seemed to be something with the torque converter.
Writing a letter to Acura about their tranny policy (if its in warranty, we'll replace it, but if it's out of warranty- go away), plus all these other people having similar symptoms. |

| It's nice to have the problem I have experienced for over two years in my 01 MDX explained so well. I took delivery on this vehicle Nov 2000. I figured the trans recall would fix things. They put the jetpack in and two days later the MDX was still slipping. Very intermittant ... only about 5% of the time at the 20-25 mph slow accel. I took it back and they REPLACED the transmission. They said they were able to reproduce the problem. Install was completed over a month ago and I have not experienced the problem since. NO CHARGE. These 01 MDX now have 100K warranties on the trans. I guess the later models had the 100k warranty already. They must have grandfathered it back to the orig first year models. My vehicle had 51K when the new trans was put in and now it still carries the warranty to 100K. No mention from the dealer of any EGR valve as being responsible for the problem. I have not had this valve replaced. |

MonsterLuv, thanks for sharing your experience.
I have called Acura customer service, and they left a message to have me call back. The first customer rep suggested I not have the
car serviced at an outside tranny repair place until I had talked
to the customer case manager assigned to my case.
I have not been told that my tranny has the 100k warranty, so
I am not sure the deal you got is for everyone. But I will ask...
Thanks,
Ben |

'02 MDX 33,000 miles
jet kit installed last year
started sensing shudder at low speed, slight incline and light accel 8 months ago
brought in many many times until they replaced EGR valve
problem remained....
now suddenly they discover tsr telling them to replace torque converter and computer chip.
parts due in a few days...hopefully that fixes it.
This has been a royal pain in the ass for me. |

It's a brand new TSB. It just came out last week. The TSB says that if a shudder exists only between the speeds of 35-40mph...and the EGR valve is not the cause...replace the torque converter.
The TSB is pretty specific about the window of vehicle speed. If you're feeling a shudder at say, 20mph...or 50mph, they're wasting their time with replacing the converter.
I have diagnosed and replaced many transmissions in MDXs and TL/CLs (they both fail the same ways)...and I have never diagnosed one with a shudder specifically between 35-40mph. |

We have two different kinds - a "STUTTERING" - one type is not as
noticeable and it occurs under light acceleration around 20 and 40.
The other one is very noticeable "SHUTTERING" and occurs various
speeds between 15 to 45.
We love the MDX and this is the only big problem we have ever had.
It does not make the car undriveable - I just dont know when it
might become more than a nuisance and cause us to be stranded
or an accident.
By the way - anyone have a link to that new TSB? |

My '01 now has 65K on it. I had the transmission flutter problem at 45K miles. Happens around 35-45mph. Sounds like you are on grooved pavement for a few seconds. Anyway the service mgr said it was the torque converter plates chattering against each other as they try to sync up for a few seconds. He said we can flush the transmission 3 times to get it good and clean and that will stop it. He then said if it comes back (and it probably will), they need to replace the tranny which they would do later under warranty since I would be on record in the computer with this issue.
He was right, the problem stopped. Now I have 65K as I said before and it just started again. I called the guy back and he said no problem they now have a torque converter kit for this which just came out in the last several weeks. He called the regional rep and they authorized the work under warranty. They will pull the tranny and install the new "kit".
By the way, my guy said that the trannies did not change much from '01 to '04. Just some minor internal changes (oil jets) but otherwise they are the same. If you are having the problem I describe I think you have a troque converter issue. My service manager mentioned the EGR valve but said it is only the culprit in 5% of the cases. He did say if the noise occurs at 60 mph or higher, that would indicate a possible EGR problem and not the torque converter.
I will post in a couple of weeks and let you know what happens. |

Your "guy" should be ashamed to call himself a service manager.
They are completely different units from the '01/'02 models and the '03 and up models. About the only ting you could say is the same between them is that they are both 5-speeds. |

| '01 MDX with 48K miles has had a similar problem for the past month. After hitting cruising speed at about 35 and 45 mph there is a pronounced shudder when maintaining speed as the RPM's drop to between 1,200 to 1,500. I was able to duplicate the shudder for the service rep quite easily and he quickly referenced the torque converter tsb. He is scheduled to call me back tomorrow after reviewing warranty info. |

Sounds like my MDX has caught the tranny bug as well. '02 with 45k. In my case, I notice the shutter at about 60mph in 5th with veeerrrry light throttle. Let me know if anyone thinks otherwise.
During the last service I mentioned it to the dealer who, of course, could not recreate the problem. Sounds like I will have to take them for a ride.
Funny, or not so funny story about taking service techs for a ride. A dealer replaced the rear dif gears in my Toyota pickup because they were shot. Next time I engaged 4wd, the whole truck ground to a stop in the middle of the road. Took it back to the dealer and told them they put the wrong ratio rear end in. Took them for a ride (on dirt to save the driveline) and ground the truck to a stop. They still denied anything was wrong! "In 4wd, it is supposed to feel different..." they said. Yeah, it's supposed to stop? I had to convince them to open up the dif and count the teeth. They were surprised to find they put the wrong gears in. Oh, and if you were wondering who: Toyota 101 in Redwood City, CA did this.
