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].

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.

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.

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.
