Torque converter lock out

Discussion in 'General Motoring' started by Elliot Richmond, Feb 1, 2005.

  1. Hello group,

    I have a small problem with my 1993 Honda Accord. 2,2 L. The torque
    converter lock out clutch works erratically. It usually does not
    engage until the transmission is really warm (after 50 miles or so of
    high speed operation). But, it does not reliably engage even then.
    adding to the puzzle is that the lock-out clutch will occasionally
    engage (two or three times a week or so) even when the transmission is
    relatively cool.

    Here is my question, Is this something I need to get fixed soon, or is
    it likely to go on for an extended period of time? As a corollary to
    that question, will the #@*& thing leave me stranded on a dark and
    lonely road some time?

    Thanks in advanced for all your help.

    ===========================

    What's the mileage, and what was the mileage when you last changed the
    tranny fluid. Did you change it twice? Was it Honda Z1, or something else?

    A bad thermostat or low coolant level will also interfere with torque
    converter lockup.

    check the temp sensor/sensor wiring also.

    there was a thread on this group a while back with an excellent
    diagnostic using led's hooked up to the sensor & solenoid circuits.
    google is your friend.

  5. I should have included that information. The car has 150,000 miles on
    it. The car and the transmission have been serviced by the dealer at
    the recommended intervals. The dealer suggested I take the car to a
    transmission shop, as the dealer does not service transmissions. I
    thought that was odd. I have had generally bad experience with
    transmission shops and good experience with dealers.

    In reference to the other suggestions, the car does run a bit on the
    cool side, and the last couple of months, the temperature gauge has
    been acting strangely. So, I do plan to replace the sensor and the
    thermostat. I will post the results of that experiment.

    Thanks for the help.

  6. Correction to my own post. I meant to say the dealer does not REPAIR
    transmissions. They do service them.

    Elliot Richmond says...
    A new thermostat worked for my 94 with the same problem. A
    new thermostat is a lot cheaper than any transmission
    repair.

    Just make sure you bleed the air out completely when you
    refill the coolant.

    I had somewhat similar problem or at least a problem with the lockout on the
    torque converter. When I reached 60 mph the lockout would release and my
    RPM'S rise as it reverted to overdrive or fourth gear. When I pressed the
    gas pedal it would then go back to lockout rather than to a lower gear for
    acceleration.
    The fix was the adjustment on what I call the throttle pressure cable. I
    removed the play from the cable. It is a cable right next to your regular
    throttle cable on your throttle body that goes down to the transmission on
    the right front of the car. If there is any slop in the cable, loosen the
    nuts that hold it to the bracket and adjust out the play in the cable.
    Retighten the nuts and try it out. If that works and the gears seem to shift
    hard after that, back off your adjustment 1/2 turn at a time till
    acceptable. Good luck,
    Howard
