Answer
You have a fault in the TORQUE CONVERTER CLUTCH SOLENOID circuit.

You ALWAYS replace this item anytime you have to go into the tranny because it has a high failure rate when it starts to get some miles on it.

It IS possible that the fault could be in the TCC brake switch but the circuit needs to be tested.

If you are mechanicaly inclined or know of someone who is, You will need a DIGITAL MULTIMETER, Simple electrical schematics, Test procedures and picture locations of the components within the system that is causing you problems of which can't be done on this website which only allows one picture. I do not have a website so you will have to e-mail: onlineautohelp@msn.com in order to obtain the information.
