Have code need advice

I hope you guys can help, I have a 96 f 250 w/e4od & a b&m shift plus electronic shift improver. The truck shifted fine one day, the next day it was upshifting very hard in every gear. I checked codes & got a 625 (electronic pressure control(epc) driver open in pcm. I have disconnected b&m & checked wires which were fine. I think i should replace the pcm but can any of you think of anything else this could be. Your opinions are appreciated. silvers

It was the pcm. I can't prove it, but I think the b&m shift plus fried the electronic pressure control circuit. I'm not the first person this has happend to.
