2000 Neon torque converter won't "unlock"

A friend has a 2000 Plymouth Neon with auto transmission. Trans fluid almost all leaked out (bad radiator connector) but she still drove and so did trans damage - trans slips. The car is still drivable but the biggest problem is when she comes to a stop, the car starts to shudder and the engine seems to stall - just like if you still had the car in gear with a manual transmission. The car will stop shuddering and eventually stops stalling and then sounds normal. My guess is that the locking tourque converter won't unlock right away. Is there some solonoid or electrical connector I could disconnect easily that would disable the locking mechanism? If I did this, do you think this would solve the shudder/stall problem? Would I just be creating other, new problems with it disconnected? What else could it be (just a bad torque converter?)? Thanks!

 

Most likely the entire transmission is toast. Heat build up is death to a transmission. I would expect more damage then just the TC. I would expect a full tranny rebuild or replacement as the only option.

 

There is a connector you can unplug that will effectively stop the TC some locking up. Keep in mind that it will generate more heat unlocked, which won't help it's already shortened lifespan.

Sorry, but I don't know where the connector is...
