    Question Tcm

    Hi folks, this is my first post and first problem with my '08 2500 4WD diesel. I am getting a P0880 ..".TCM power input signal" on my Edge scanner. I first noticed the "Service 4 wheel drive" signal after replacing the batteries! What did I do wrong, and do I really have to use a Chev dealer to do the repairs. Any ideal of the cost?
    Will it hurt to drive it...with this problem, as I live 20 mi. from a town?
    Thanks for any help you can give me!
