    On my 1987 740 with the AW70 tranny, here's what's happening.
    Everything shifts smoothly, but it seems like first gear goes the
    normal range, then it shifts into second and almost immediately drops
    into 3rd.

    I did tinker with the kick-down cable a while back while trying to
    diagnose a problem. Nothing seems to be sticking, and at highway
    speeds and cruising town it shifts effortlessly.

    I have 199,000 miles on the car. Any idea as to why it goes from 2nd to
    3rd so quickly?

  2. TRy adjusting the kick-down cable as per spec. Information is on the
    Brickboard.

    All the best, Peter.

    several years ago, when I first got my '89 240, I flushed the tranny using
    the procedure below. I believe I found it thru this newsgroup. The only
    thing I did differently was to use one quart of synthetic fluid at the end.
    Car has shifted perfectly ever since... I've got 230,000 miles on it.

    ====================================
    The transmission could be flushed/refilled by you at home using new, clean
    transmission fluid, meeting DEXRON III G specifications. (Total volume needs
    to be at least16 liters) Check your owners manual to make sure of the type
    of fluid you should be using.
    Remove the battery and battery shelf. Remove the return hose on the control
    system (valve body). Install a plastic plug in the connection on the cover
    (valve body) and a transparent plastic hose on the oil return hose
    connection. Position a container for the oil with markings for the volume
    under the hose. Temporarily reinstall the battery shelf and the battery.

    Apply the parking brake, gear selector in park, start the engine and allow
    the engine to idle. Switch the engine off when 2 quarts of oil have been
    pumped out or when air bubbles become visible in the hose. Top up with 2
    quarts of oil. repeat this procedure 7 times. Check the color of the oil,
    when the color of the oil is clear red (as new oil), switch off the engine
    and connect the return hose to the control system (valve body) cover. Check
    and adjust the oil level.
    The above procedure is the official Volvo procedure for flushing the
    transmission. It is a bit simpler to disconnect the top connector at the
    radiator, you can do this just know that you will not be flushing the cooler
    when you do this. Transmission Fluid should last forever, but driving
    conditions and time have shown that things don't always turn out in real
    life like they do on paper. The newer transmissions with lock up in the
    lower gears as well as some transmissions even go into neutral at a stop
    should make the fluid last longer, keep your eye on the fluid condition and
    change it when needed. (your mileage may vary)

    Transmission Line Removal

    To remove the transmission line pry open in the direction of the yellow
    arrows to open the clip, and then pull in the direction of the blue arrow.
    This is the top connector and it is the one we disconnect at the shop. The
    top hose is the fluid coming from the transmission, the connection down at
    the bottom (Green arrow) is the fluid returning to the transmission after
    passing through the radiator for cooling.
