      Check for any codes. There may be something serious that the pcm picked up on that the computer is limiting and preventing damage to.

    All gages go from one extreme to the other and transmission stops pulling. let up on gas and gages go back for a min.
    Gages act like there is an electrical issue. I don't know where to start to solve this issue.
