Did you do the trans yourself? If not go back to who ever did it? Otherwise I would look at the wiring coming from the trans. Possibly one of the wires are broken, frayed or grounding out.
Always go back to the last thing you did before it went wrong.

Other wires coming from the ECM grounding on the wheel well behind the air filter? Did it ever have a lock up switch? Does the trans relay still function as it should? Does a 96 have a relay?

It would make me think that it almost has to be one of the wires that you use for the tc lockup switch being ground out. Not saying the conveter can't f up and stay locked, just havent ever heard of that.
