If you plan to keep the car for many years, then consider a fluid change now, rather than wait. Not a flush, just 1 drain and refill. If the fluid is very miscoloured, then get 1 more change a couple weeks later.

I see the transmission is a DCT. So don't inch along in a que at <about 4 mph.
Drive like a manual or a big lorry, let it Idle along at a rolling pace, without having to go in and out of 1st gear.
Keep a gap ahead in slow traffic

Drive just like an automatic > ca 4 mph, no need to lift your foot for gear changes.
However at speeds < about 4 mph, drive as though you were in a manual. Keep a gap ahead and avoid repetive 0-4 mph start stops.

You will notice if you do it that, that the motion of the vehicle may not be so smooth.
Apart from that lowest speed range, DCTs are fantastic.
