My 2014 XC90 has a periodic shutter when going through 20 MPH

What is your question?

My 2014 XC90 has a periodic shutter when going through 20 MPH that feels like it wants to stall. Appears to be more prevalent going up an incline at the same time. Dealer did not see any codes when I tool it in. Seems like transmission but this car has a closed transmission so can't change fluid or any other trouble shooting.

What makes this problem better or worse?

going up inclines
