Pcm Upgrade

Sorry if this question has been asked before but, I have a early 99 250 4x4 auto with the 7.3. People have said if I upgrade to a newer PCM the tranny will shift better. How new can I go without problems? I am looking at one from a 2002 250 4x4 w/ 7.3 auto. Is this to new or will it work?

Will they be able to reflash it so the tranny has the firmer shifts everybody is talking about?
