I purchased a 91 mustang gt 5.0 and i took it into shop the day after to get the flex plate replaced. Due to the fact when i started the car it was abubtly loud when starting. After replacing flexplate, the feller started it and it sounded the same and i was confused, so i questioned him about it and come to findo out a piece of
tranny was broke. Now when i say peice i was a chunk where 2 bolts would mout to my engine, was gone, he said he could stick his hand trough it.

now whats the easiest fix for this problem? new
tranny, new casing, help help help, and by the way, im driving it like that, due to the fact, it shifts great and havent had any problems with it yet. but def want to get it fixed
