RPM Fluctuations

My 2011 with a 120K on the clock was doing the same thing. I did a full transmission fluid exchange and there was significant improvement. Every once in a while I'll still notice a very slight fluctuation on the highway, but it hasn't gotten any worse over the last 10,000 miles. I think I've seen some threads threads where the ultimate problem was identified to be some the torque converter going on and out of full lock. They seem to go for a quite a while in this state though so I'm not too concerned currently. If the trans fluid is old, try a refresh of that

Well, I just had my local independent do the transmission service / fluid change -- and there is definitely significant improvement. This has also improved the torque convertor judder / shudder that I had at 50-55 MPH and at lower speeds under load. Thank you very much for the suggestion!
