Shudder/Shaking at 35-40mph and 70-75mph

I was asking the same question here several months ago. The gentlemen who went to a harmonics lab then gave some very good advice, further back in this thread. I have since spent more time on getting it resolved.
I have a 2010 V6 4WD with all options. Bought it used (my second 2010 CT -- traded the first one, regrettably) with 102K miles. Now have barely 104K. Long story short, I am the fourth owner (it's in great shape) but it is obvious from the service history that there were MULTIPLE attempts to correct the transmission/torque judder all the way from realignment to new brakes to new tires, suspension, etc., etc., all to no avail!
Long story even longer, I have now gone direct to Honda via the NC Attorney General's office, requiring they completely cover a new torque converter. It's complicated but they are required by law to do so. I'll let everyone here know how it turns out. BTW, I'm retired so I have plenty of time to work through all the red tape.
Anyway, the judder is most likely the torque converter [see Honda TSB's 16-066 & 16-067] in my humble opinion.

Hi Beerhunt (great name),
I have a small claims court summons to American Honda in process. Trial is set for March 9, 2024. NO response at all from American Honda to emails or certified mail to date (1/24/24). I will be representing myself [no lawyer]. I am not pinning any hopes on the case just yet, but I personally won a similar suit against Ford Motor Company (which surprised the heck out of them!) because the law was on my side. See the Magnuson-Moss Warranty Act of 1975 for more information on warranties, especially extended warranties.
I'll try to forward an update. Thanks for asking.

BTW, I meant to say that I only have the judder at +/- 28 mph under light to moderate throttle and can power through it so that it isn't noticeable. Still, not a proper solution. Messes up an otherwise great car. Oh, and I have bypassed the VCM [see many discussions here].

@ chuand,
wow I am surprised at such a quick response and appreciated!!...and thnx for complimenting my nic also!
I instailed the VC Muzzler ll myself approx 2 yrs ago and I still get a slight shudder within 4-5 seconds AFTER initial acceleration from a complete stop and no other times. It doesn't do it every time though. My 2010 CT has extremely low mileage (46,000) and I may be due for a transmission drain/flush. I am definitely going to call the loco stealership and inquire about the torque converter possibly being the culprit.

I am hoping that you WIN your case! Good luck!

Thank you so much. Check out the two TSB's I referenced. They pretty much lead to the torque converter. Not to say that other components cannot be compromised (engine mounts, axles, etc.). And I am not a mechanic, so I rely on others' expertise here.
Good luck with yours.

What's the latest on this?

Hi Beerhunt,
Thanks for asking. Mecklenburg County NC's new online court system insists I didn't submit a proper complaint form, so everything came to a screeching halt. A District Manager for Honda America showed up, so I have their attention. They have to take this case seriously because of the Magnuson-Moss Warranty Act I have mentioned (Google it if interested).
Bottom line: Trial is rescheduled for 6/4/24. Jeez. I'll plan to update you all.

A bit more just for everyone's information, I am the fourth owner of this 2010 Crosstour. I have the Carfax report. It was certified twice as a Honda used car, btw.
If you look at the combined service histories, it is amazing all the remedies they kept trying over and over to fix the "judder" from BRAND NEW including wheels, tires, suspension, shocks, struts, etc. Everyone assumed it was a suspension or tire or alignment issue. No one in 2010 apparently knew of the torque converter issue, so they all spent incredible time and effort (under warranty) to decipher the torque converter issue, but no one ever did (or admitted to it).

Some of you may have been following my legal pursuit of Honda to get them to replace the torque converter on my 2010. The short answer is that I lost. BUT, I did persuade Honda to give me a $1000.00 gift card for my trouble (one whole year!). So, I'm probably giving the gift card to my personal mechanic so he can buy parts and give me a discount to do it. Honda's quote was over $4K !!

I wanted to bring anyone who is interested up to date on the "judder" issue, so am replying to my own post. After all this time, I had the very best mechanic I know drive my 2010 4WD and he immediately said the vibration was NOT the torque converter but the transmission. One reason is that it does not judder at a higher speed. He said some transmissions just get warped internally at some point in time and the only solution is a whole new tranny @ $3-4K. He said it's not worth it and just to live with it so that's what I'm going to do! I did get a $1K "Loyalty Card" from Honda for all my time spent.

My mechanic is scratching his head about what is making my 2012 CT v6 4WD shudder/shake at 35-40mph and again at 70-75mph. When on the lift he cannot find any visible signs of something being wrong. But go down a side road at just about 40MPH and you can feel something is not right. As the driver you feel it in the wheel and pedals and seat. As a passenger, you sorta feel it. I think our bodies are just used to feeling stuff like these so the brain compensates. Driving with something which is prone to rattling sitting on the passenger seat (like and empty pet carrier), now doubt something is wrong.


My mechanic wants to wait and see if it gets worse so hopefully he can say ah-ha! when looking at the belly of the beast. He doesn't have to live with it every day. He also doesn't want me paying hundred to thousands of ours on a fishing expedition.



Anyone encounter anything similar.


My CT has 135,000 miles and is up to date on all of its servicings.


It does not change with engine speed.

It sorta feels like it is lugging, but forcing a kick down does not make it go away. Only speeding up or slowing down to get out of its trigger zone makes it go away.
It seems more pronounced when everything is good and warmed up.

I have a 2011 CT E-XL, and ended up with a similar issue, which was caused by my fault for inadvertently driving in D3 at high speed. This was over 80,000 Km's ago.
This damaged my Torque Converter, which now needs to be replaced, and tranny rebuilt. Estimated cost about $4000.
I can still drive it but I feel it while driving in the city or highway.
