OK to Use???

I have a 727 reverse pattern transmission that has been stored for the last 25 years. It was working fine when I switched to a PG. Plans now call for it to be used behind a Procharged 360 which I will be building shortly. Will be a street car not raced. Question is should there be any special maintenance on the 727 prior to it's use?? It has been stored with trans fluid in just as it was removed from the car.
