It is very unlikely for the tcc clutch to fail and cause a lock-up on its 
own. The clutch would have to be enabled and then jam internally in the 
converter, I doubt it would ever disengage after that. An uncommon problem 
that I've seen a couple times is the tcc valve in the pump sticking after an 
apply, this keeps the converter locked up whenever the engine is running. 
Those always get a new pump.
Good luck,
Al
