    My '97 Concorde has 80,000 miles on it, problems started at 74,000 miles
    with check engine light, but no shifting problems. Code showed bad torque
    converter, which was replaced. 6,000 miles later and now having problems
    intermittently with car stuck in "limp mode". TCM was replaced, they said
    ciruit was open. Worked ok for a couple weeks, then problem recurred. It
    does not happen every time, maybe once every 2-3 times of being
    started(sometimes more, sometimes less). Doesn't seem to matter whether
    car is cold or hot. Speedometer at times goes haywire, moves from zero to
    60-70, then goes back to correct speed for being in limp mode. It is
    noticeable that when shifting into gear after starting the car, if it
    shifts hard to reverse, then I know it will be in limp mode for that time.
    Otherwise, with no hard shift, it will be fine. As long as the car
    remains running (if not stuck in limp mode) then it shifts perfect. I
    love the car, just not dependable, and dealer wants 2500.00 to tear it
    down to find out the problem. I'd appreciate any input. Thanks for your
    help.

    I forgot to include that the engine light is not on when the transmission
    goes into limp mode, and dealer says no codes are showing up. Thanks
    again for your input.

  3. Sounds like a bad speed sensor or more likely a bad ground somewhere. The
    trans uses the output of that sensor.

    i would check out the output speed sensor esp. since it has had prior repairs
    because there could be metal shaving stuck to it and causing a lost signal

    Thanks for the input. We took the car to the shop and had the output
    sensor replaced, wiring harness checked thoroughly (twice). Still having
    the same problem. Sometimes when you start it up it is in limp mode,
    other times it is just fine. No check engine light. We are at our wits
    end with this car! My husband takes his tools with him so when it does
    this, he unhooks the battery cables to reset computer, then it will work
    for that time. We're about to give up on this car and cut our losses. If
    anyone has any other ideas, we'd appreciate them. Thanks again.

    check fault code in the pcm and the trans controller cluster and abs module if
    it has abs before doing anything else it might give you a better clue as to
    what is going on

    I wanted to say thanks to those who responded to my questions about the
    problems I was having with my Chrysler Concorde's transmission. While my
    brother was visiting, he checked out the wiring thoroughly again and did
    not find any problems. However, he found anti-corrosion material in the
    part of the wiring connector of the output sensor that plugs in the
    transmission. After he cleaned all that out, we now have a good
    connection and the car no longer goes into limp mode. It has been two
    months now, with no problems. I would never have thought the source of
    the problem would be something that was added to protect the connection
    actually caused the bad connection. (A transmission shop replaced the
    sensor, so I don't know if it came that way from dealer or if they added
    it). Just thought maybe others were having similar problems and this may
    also be their problem... Thanks again all.
