Thanks for the info! What are the ramifications of operating too long / far without solenoid connected?

You could try to disconnect the solenoid to see if it is the problem. Should be a 4-prong plug that goes into the transmission. Disconnecting the solenoid will not allow the torque convertor to lock.
Higher than normal transmission temperatures that could damage the transmission, however, I ran my 700 for 3 years without a lock-up convertor, and noticed no problems. I'd say you'd be fine to disconnect it, run it out on the highway for a short test, and see if you still have the problem.
