Engine noise and rough shift

[Tdom1979]

I just started driving a 2007 Volvo XC90 3.2 AWD. It has 130k miles on it and seems very well maintained.
It has a grinding/humming noise that seems to come from the front passenger side and that starts when I shift into drive. Then it shifts rather rough from 2nd to 3rd gear. It actually almost double shifts. I can see the RPM jump a little... , and depending how hard I accelerate it almost knocks when shifting into those gears.
The grinding noise seems to get less once I hit about 40mph and the shifting issue seems to be less once the car warms up.
Any advice? Would love to figure it our without having to take it to a mechanic.
Thanks
