Hi, I have an '07 AWD with V6 107K miles. It has started to hesitate a little, very subtle, from what it feels like changing gears from 2 to 3. When accelerating hard, it stutters but runs fine after that. My understanding is that the tran is sealed, so I cant replace the fluid or have it checked. It was suggested that I take it to the dealership and have them runs a software diagnostic??

Anyone experiencing or experienced this? What did you do?
