    Turn key get nothing - 01 SLC 1 AT, only courtesy light and clock work. Automatic, tried start in all shift positions w brake on - nothing.... Battery has good connection and is fully charged. Happened after we did a transmission valve body change. Never had this problem before. All wiring appears back to normal (hooked up). ideas?

    Sounds to me like it's park/neutral safety switch related ( white connector 2 thick purple wires ) which is right in the neighborhood of what you were working on. Car won't start with that disconnected.

      It could be the safety switch. If that is installed then the next thing I would suspect would be that the BCM lost its learned value for the ignition switch. You can try to perform the 30min learn process to relearn the ignition switch to the BCM.
