Default Transmission problem. i think

my automatic 90 cherokee likes to rev high when coming out of 1st and 2nd but then not even get above 1500 rpm when in all the other gears until i finmally get up to speed. when im up to speed and just cruisin it likes to occasionally jump from 2000 to 4000 and back and forth. any advice?
