I have a 2015 Q70 Sport 3.7 with 120k miles, and I've never changed the automatic transmission fluid. I was curious what others have done with this. Can the fluid be simply checked by the dealer, and it may be "okay," or should it definitely be replaced, etc.? Does anyone know what the estimated cost should be? Thanks

120K is definitely past time for a spill and fill. If it isn't giving you issues and the fluid isn't muddy, just go ahead and get it changed. Brown or varnishy-burnt fluid is okay, the main thing is that it's still transparent and not muddy. If it's turned to mud, leave it alone and run the transmission till it breaks.

IIRC there's no stick on your '15, but you can get a sample of the fluid by cleaning the area of the drain plug, then loosening (but not removing) it and letting some fluid dribble out into a cup.
