4L60E Shifts too soon???

SHIFTS TOO SOON, through all gears?

my recently rebuilt 94 SWBRC 350/4L60E shifts from 1-4th way to fast unless i am really accelerating. if i take off at a fairly slow pace it will shift out too fast. sometimes it hunts through the gears up and down unless i accelerate or let it coast. never slips and shifts fine under moderate acceleration. any ideas?
