Question about Honda Civic
That code, P0740, is a torque converter clutch circuit malfunction, according to the published OBD2 fault codes. You may be able to clear the code by disconnecting the battery for an hour or so. I'd start by doing that, and then drive the car to see if the code comes back. Even if you don't have a code reader, if the car is driving strangely, and you clear the code with a disconnect of the battery, you can tell if it comes back when your check-engine light illuminates and the strange driving conditions return. Sometimes a momentary glitch in the car can trip a code, even if there isn't a real failure, and a reset will clear it for good. If you have a consistent code that returns, then it's time to dig deeper. See if disconnecting the battery for an hour or so clears the fault light and code, and if it comes back. If the disconnect doesn't clear it, you could have a shop clear the code with a scanner, and then see if it returns. Post up what happens and we can continue to figure out the problem.

If there an other code?.
If yes Fix the other code first.
Check if the stop lights work correctly.
Because the Torque converter clucth selenoid, recieve voltage from the brake pedal position switch.
But everything is OK.
I recomend Take the car to a Automotive trans. place.
Because before to replace the selenoid.
Is nessesary do a few test. With a scanner and Pressure tester.
To check if the converter is good.
OK> I hope this information can help on your problem.
