Wow- that's something to keep in mind!I was tormented with this problem for several years and found a solution. In my case, it had nothing to do with axis, tires, or brakes problems. The problem was solved by replacing Oil Pressure Switch # 37240-R70-A04. Good luck to all! Ready to answer any questions.
I just recently bought a 2010 and mine occasionally also has the 20-25 mph shudder. That oil pressure switch is a $10.00 part from Honda parts direct, worth a try for that price. I don't see how the oil pressure switch would cause that problem, seems more like a transmission issue but if it works for one person it might work for another.I was tormented with this problem for several years and found a solution.

If you own a 2010-2012 Crosstour V6, the ATF filter is internal, only serviceable if you unbolt the transmission from the engine. I found this out after I bought the filter from Rockauto for $10 or so, several years ago. It was going to cost $6 to return it, so I kept it. I take it out to play with every now and then. I get bored and stick it back in the box.7/11/2020:
I have been fighting the same problem for a year. I have a 2005 Accord 4cyl AT (85k miles) that would vibrate under light acceleration at 22 mph. Could feel the vibration in the steering wheel and floor.
The good news is that I finally got it resolved and since there are very few posts (none that I could find) of an actual solution to this problem, figured I would add mine.
The car has good new balanced tires, new struts, new wheel bearings, new stabilizer bar links, new brakes/rotors, new aftermarket axles and a fresh transmission service. Yet, the vibration still persisted.
I was down to having to throwing engine and transmission mounts at the problem but didn't want to do that since I can't see anything wrong with them and I'm tired of putting $$ into this car.
I got to thinking that maybe there was an issue with the transmission. When I had the transmission serviced at Honda, I asked them to replace the fluid and filters. They replaced the fluid but said the filter wasn't a service item and they don't replace those. I thought that was strange since it's just an inline canister filter that sits between the air box and the engine (mounted to top of trans), easy to get to and inexpensive.
Anyway, I decided to replace the filter myself since it was cheap and 15 years old at this point. THIS SOLVED THE VIBRATION PROBLEM!!!!
Hope this helps someone.
