Vibration over 40 mph.

Just a hidden problem cause the slightest vibration and took out my tourqenverter seal ,blew out fluid and smoked my $3000.00 transmission. How would you guess it was paint thickness away from the tourqenverter sitting flush at the back of the crank and some 1 tell me what they see , how would you know ? Or am I missing something .
