I have an 07 4 cylinder automatic Accord with 50k miles and the car exhibits a rumble strip feel and sound while going through shift points, usually around 40MPH. At least I believe this anomaly is occurring at or near shift points. Seems to be more prevalent when car has only been driven a few miles. Otherwise, car performs well.
Anyone had this problem and what is the remedy. Thanks

 

yeah it's time to change the trans fluid
