Could this be? Yes, all the above but the output speed sensor circuit is suspect #1 according to the code. That eliminates the solenoid pack for now. What's not making sense in reading forums for many years I don't think I've ever read of a speed sensor circuit failure causing no shifting whatsoever and locking up the transmission. You may have more problems then the speed sensor circuit. Course I'm not a tech either.
Considering just the code the output speed sensor is the most likely culprit and is the fix most of the time. It's located on the front right of the transmission. They cost around $40 but prices vary. Check the connector for corrosion and security. Remove it with a socket/ratchet. You can test it and the wire harness with a multimeter. Just be aware the TCM and PCM can also cause the signal to fail. If you ever get it moving again you should notice the speedometer is dead or erratic. It uses the output speed sensor as a signal source.
