94 Intrepid 3.5L transmission in "limp mode"?

    I started my car and it would not shift out of 2nd gear. On my way home I
    stopped for some groceries, started my car, and the transmission worked
    fine. Is "limp mode" an intermittent thing?

    If I need to replace my transmission, can you guys suggest the best course
    of action and how much I should expect to pay to fix the problem? My car
    has 146,000 miles on it. Thanks.

    It can be, if the sensor that's causing it is failing intermittently.
    Unlikely. Would the speedo happen to not be working while it's in limp
    mode?

    Don't get talked into a new AT. Probably one of 2 sensors or just a
    connection gone bad.

    The speedo was working. What sensor are you referring to?

    Which sensors are you referring to? Where are they located? How much do
    they cost? Thanks.

    There are two sensors on that transmission that might be pertinent to your
    problem (and there may well be more, but two I'm aware of). One is called
    the 'output' speed sensor, one called the 'input' speed sensor.

    If your speedo wasn't working while the trans was in limp mode, it's a clear
    indication of a failure of the output speed sensor. I paid $26 for mine at
    the local Autozone, and after about an hour's worth of jacking up the car,
    finding the part, finding the tools, etc., I was back on the road with no
    trouble since. Easy fix, and cheap, too.

    Your problem is probably *not* the output speed sensor, but may well be the
    input one, or it might be a problem with the connection or the wiring
    harness. I don't have my FSM handy right now, so I can't tell you for sure
    what the diagnostic procedure is, but I imagine the part is similar in cost
    to what I paid for the output sensor, and I can tell you for certain that
    swapping it is similarly easy. Both are located on the driver's side (in an
    Intrepid) of the transmission, one is slightly forward and below the other.

    I'm sure others on the list can fill you in with the details about the input
    sensor.

    Good luck,
    --Geoff

    Probably easiest way to get full instructions is to go to
    www.google.com and visit the group page and search this group's
    archive for the word "sensor" and/or "transmission". I bet you'll
    find exact instructions for your model. I sold mine a few years ago.

    This thread on the 300M ezBoard may help:
    http://pub88.ezboard.com/f300menthusiastsclubfrm23.showMessage?topicID=46.topic

    There's an FSM sketch of the sensor locations in that thread. The
    thread also gives the part numbers for the input and output sensors.

    You'll need a 1" socket - may need a deep well depending on the length
    of your particular socket. My standard socket barely reached the hex
    grip of the input sensor on my Concorde (same sensor as yours), but it
    worked. Another brand of socket might be slightly shorter and not
    work. An easy 20 minute job for the first time DIY'er.

    BTW - Koller Dodge referrenced in that thread no longer does internet
    sales. Might try www.mechanicsvilledodge.com for good pricing. I think
    the price at local dealers is typically $20 to $25.
