Welcome.
GE probably didn't put in the effort to explain because in GE's eyes the model T transmission was merely an "assembly" replaced as a whole. GE used to have rebuilding programs for their FF transmissions. FF transmission could be opened, repaired and put back into service. Model Ts were merely disposables. In fact most model Ts were scrapped rather than rebuilt or repaired.
But I will say this, I am kicking myself for not opening up a post FF transmission now. As they saying goes- know your enemy. I didn't care too at the time which I now regret.
