    We have a 98 concorde 3.2l that has lost its speedo, odometer lights up
    but doesn't count. It will also not shift past first gear. Something about
    an input and output speed sensors? TIA.

    Yes - output speed sensor. It's actually stuck in second, not first,
    but understandably hard to tell (except when starting off from a stop).

    If you have more time than money, you might want to pull the existing
    one out and see if metal dust has accumulated on it. Mine went out a
    few weeks ago, and there was quite a coating. Since I already had the
    new one, and it cost under $20, I went a head and put it in. I would
    almost bet that if I had cleaned the metal dust off of it and put it
    back in, the old one would have worked. (The type of sensor detects
    presence and absence of metal to generate its pulses from the park cog -
    it can't tell the difference between a gear tooth and a heavy coating of
    metal dust, so it probably never sensed the absence of metal.)
