Trans cooler lines LOVED to blow up on those things. Sadly, if you ran it until it stopped, there's zero hope of salvaging that trans.

It's not even a matter of just lubrication... in an auto, the fluid is a coolant and hydraulic fluid as well as a lubricant. If the bands/steels didn't go first (lack of hydraulic pressure to fully actuate the proper bands, allowing them to slip and burn), the torque converter and/or pump wouldn't be very far behind. From what the OP is describing, that sucker is toast. Sorry man.
