One problem related to automatic transmission torque converter has been reported for the 1999 Honda Civic. The most recently reported issues are listed below.
While driving down the highway doing 60mph, my check engine light came on so I pulled into a local parts store had them look up what had made my check engine light to come on and the code that showed up was p0740 (torque converter clutch circuit malfunction). Now my car is having hard times shifting up and down in all speed ranges. I have been researching this problem and have found several complaints but no action taken.
