Need advice on an 02 Jeep liberty

So I bought this guy not too long ago, engine has 165,000 whereas the tranny has 100,000 miles. It has a bit of aggressive shifting when going over 30 mph and when I’m on the freeway, going over 60mph the RPM’s won’t go below 2, typically stays between 2 and 3 but won’t shift. Please tell me there’s some easy fix to this!!
