Not sure if I understand your problem, it changes fine from 1-2 ok..and then 2-3 it changes ok (firm),, or does it slip (rev)??
If you mean it the engines revs dont drop (keep revving) on the 2-3rd change, it sounds like the D/R clutches are burnt, and you will lose reverse soon too. Smell the oil to see if it smells burnt.
If so its time for a rebuild as the clutches don't usually burn out by them selves the auto has been to hot or there's a hydraulic issue, old pistons, seals. ect.
