I have a 2015 Accord v6 EX (Automatic) - It currently has approximately 42000 miles on it. I have noticed it started to have a hard jerk when shifting from 1st to 2nd gear and from 2nd to 3rd gear. The high gears shift normal. When idling I feel a loss in power but then it immediately jumps back up to normal (Almost like it wants to shut off). I even drove it with the Eco button and still the same. I drove it in the sport mode and had no issues. Any suggestions on what it could be or how to fix?
