P2770 Open in Torque Converter Clutch Solenoid Valve Circuit

SOURCE: i have a 1998 honda

I am having the same issues with my 98 Accord. The transmission in the car slipped and bucked for a long time, but now it is stuck in limp mode. Most opinions are that the car needs a transmission, but that is horrendously expensive for a 98, so I have been trying other remedies first.

Yesterday, I removed and cleaned the filters behind the lock control/shift solenoid (they were clogged solid), but the car is still more-or-less stuck in limp mode. The lock up control solenoid is the one on top of the transmission directly beneath the thermostat housing.

Here is a link to a video that will help explain torque converter control solenoids: http://www.youtube.com/watch?v=5Jeb0KpAN_g

Also, here is a link to a support group on facebook for 6th generation Honda Accord owners with transmission problems:

P0740 is a Torque Converter Clutch Circuit Malfunction, you will need to have just this circuit tested, it is mostly just a defective Torque converter clutch solenoid in the trans or a defective connection to the trans, u do not need another overhaul.

The torque converter is a key functional part of the automatic transmission. The car computer detected a malfunction and set the P0704 code. Most likely you have over 100k miles already so it could be problems with the transmission. Most mechanics will reset the light and code if you are not having any transmission problems. It the problem comes back you will need to service or replace the transmission. Best thing to do is to take the car to a mechanic you trust and find the best and cheapest way to address the malfunction.
