Thinking there is an issue with the trans. Before I go to the dealer I was hoping someone on here knows these cars. When on the freeway when you come to an incline and you depress the gas pedal slightly to keep speed it feels like the trans slips momentarily, the RPM raises a couple hundred RPM then it goes back to where it was prior. It doesn't seem like it downshifts, maybe converter unlocking not sure. If I leave the trans in manual it doesn't do it. Also in stop and go traffic seems to surge on deceleration in the lower gears. This is the 8 speed auto. The car is new, has 1200 miles on it now.


Nicely ask service write up to have the trans tech take the car for a ride with the data recorder on it and check it out on his laptop. He will quickly be able to see the events on the screen. If you make an appt. with the dealer some times the tech will have you drive the vehicle with him so he knows exactly when it happened. In the old days some dealers would let the owner drive the vehicle with a co-pilot on it to get those recordings. You would hit he trigger when you experienced your concern.

Not sure if that is available today but you can ask.
