As with most/all newer Volvos, there is no service interval for the transmission. I just replaced my fluid for the first time at about 194k miles, and it made a big difference in the performance of my transmission. I would recommend changing it every 50k miles if I had owned the car since the mileage was lower. If I were you, I'd change it now, and again around 100k etc.
And yes, of course the car has a fuel filler. How else would you put in the fuel?
