i doubt something would be wrong inside the trans, ive built more than 10 350s and about 4 400s over the years with no probs at all. my dad taught me and he actually was there during this build too since i did it at his house. hell it took me so long to rebuild it becuase he is so slow and careful lol. i can do one in about 2 hours with a full kit, i have all the special tools for it too
