I've had this car since new and in the last year have noticed the following issue in my 2013 EX-L V6 accord has an automatic transmission and at around 40 mph tends to shutter, I can feel this slight vibration through the car. Has anyone else experienced this and what is the solution to resolve the vibrations?

 

How long since you did a transmission fluid service?

 

I will check my records tonight and let you know. But my guess is probably a couple of years, and I average 16K per year.

 

I had the transmission fluid changed by the dealer in June 2017 at 57,207 miles and currently my mileage now is at 94,489.

 

That means you are WELL past the 30,000 mile service interval recommended by Honda. At this point I would recommend what is known as a "3x3"; drain the transmission, refill it with about three quarts, drive for a few miles, rinse and repeat two more times.

 

I stopped off at the dealers service department this morning to confirm my records, and they have me getting a transmission fluid change last March 2019 with 84+K miles. I guess I need to be better with keeping my service records up tp date. So that indicates that the transmission fluid should be good at this time.

Any other thoughts for the vibrations at around 40 mph?
Should I opt to have the fluid changed anyway?

Thanks for any input on this.

 

I would have the codes read to see if the transmission is throwing some errors.

 

You might also want to check the wheels & tires if they need to be balanced, or the tread is unevenly worn, or even if a wheel is bent.

Rotate your wheels and see if the vibration seems to move to a different corner of the car.

 

Thanks Shipo and JimBlake for your replies.

Just questioning the issue if it was tires or wheels being the problem, wouldn't the vibration be all the time at any speed instead of at just a certain speed and I probably would feel it in the steering wheel?

I plan on bringing the car in to see about codes after Thanksgiving.
To bad we are getting ready for winter or I could still be driving the S2000, love that manual transmission.

Thanks again for your input and have a great holiday.

 

You feel the vibration in the steering wheel if the unbalanced wheel is on the front.

I've had unbalanced wheels vibrate only at certain speeds. It doesn't always behave that way, it seems to come from interaction between the compliance of the tire vs. the damping of the shocks.

Besides, rotating the wheels or checking them for being bent seems like a painless thing to check just to rule it out.
