Short of a dismantle of the tranny there is none except a few old mechanics tricks.
First unplug your brake light switch and disconnect the purple wire. You may have to cut it but it can be put back together. This is the power to the torque Converter. Plug the sw back in so you will have brake lights.
Put the car in neutral and about 2K RPM go quickly from drive to reverse back and forth. In 90% of the cases I have "unlocked" the converter. If it unlocks you will be able to drive the car but you won't have that 200 rpm decrease when the converter locks up.
Don't reconnect the purple wire until you have a new torgue converter installed. (About $300.00)
Let me know. I will be off line until Sunday.
