4L80E problem

what kind of vehicle? mechanical or electronic injection pump? is the check engine light on? if so, what are the codes.
my trans had the same problem when i got it. PCM picked up slipped in 4th gear and defaulted to no OD. It also shifted at 2500 rpm from both 1st and 2nd. Also it wouldnt kickdown when I stepped on it, once it got to 3rd, it stayed there until I came to a stop.
Does this sound like you problem?

no, mine is 93 k2500 mech ip, shifts through all 4 gears, then when i let off throttle i get another "shift" up, i'm thinking torque converter isn't locking, because when i touch the throttle again to maintain speed it "shifts down", unlocks? and doesn't shift up "lock" until i let off the throttle again
