Car Forum / Honda Cars / February 2005Torque converter lock out
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.

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.

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

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. >A new thermostat worked for my 94 with the same problem.

Elliot Richmond Freelance Science Writer and Editor 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 > Hello group, > [quoted text clipped - 15 lines] > Elliot Richmond > Freelance Science Writer and Editor |
