    Overdrive Off Indicator
    The overdrive off indicator light
    This light tells you that the Transmission Control
    Switch (TCS) has been pushed. When the light is
    on, the transmission will not shift into overdrive.
    Depressing the button will return the vehicle to
    “overdrive on” mode. The transmission will be
    in the “overdrive on” mode when the vehicle is
    started even if the O/D OFF mode was selected
    when the vehicle was last shut off.
    NOTE: If the light does not come on when the
    TCS is depressed or if the light flashes
    when you are driving, have your
    vehicle serviced at the first
    opportunity. If this condition persists,
    damage could occur to the

    It is most likely the mlps is bad on your trans its a pretty common problem on cougars. Go to a shop and have them pull your codes to be sure, since there is no warning light for your trans they use the o/d off light as a way of saying hey somethings wrong!
