Right, we understand it's an automatic transmission, but does it happen in auto mode (transmission shifts automatically) or in manual mode (you do the shifting manually, after having moved the shifter in to the position on the left), or both?

Either way, I'm with Trips; if this is a new 2015, take it to the dealer and let them sort it out. That noted, still post up a video when you can.
