DTC P0740 Torque Converter Clutch (TCC) Enable Solenoid Control Circuit

Circuit Description
The torque converter clutch (TCC) solenoid valve is an electrical device that is used with the torque converter clutch pulse width modulation (TCC PWM) solenoid valve in order to control TCC apply and release. The TCC solenoid valve attaches to the transmission case assembly extending into the pump cover. The TCC solenoid valve receives ignition voltage through the ignition 0 voltage circuit. The powertrain control module (PCM) controls the solenoid by providing the ground path on the TCC solenoid valve control circuit. The PCM monitors the throttle position sensor voltage, the vehicle speed, and other inputs in order to determine when to energize the TCC solenoid valve.
When the PCM detects a continuous open, short to ground or short to power in the TCC solenoid valve circuit, then DTC P0740 sets. DTC P0740 is a type B DTC.

Hopefully this helps...

your vehicle is talking to you ..here is what it is saying ,,,will you please give me some new transmission fluid foreign blend and a new filter ...about $65.00 do it yourself

What do you mean "Pretion" ?
Give us more infor to help you pin poibt what cause.

P0740 Trany converter clutch system failure
Since this is also a trany problem, test this code by getting a complete wiring diagram of the trany electronic circuit. Once you have it and identified the location and colors of the torque converter solenoids/module, it is a matter of measuring the resistance of the TCC solenoid and comparing it to all solenoids. If defective, it is will either show open or shorted connection. Don't forget the basics like checking the wires for integrity of insulation and routing (making sure the wires are not rubbing a metal or being burnt by the exhaust). If there is a chance that the solenoid needs to be replaced, drop the trany oil pan so you can verify for signs of debris.
TIP:
To manually test your TCC solenoid before replacing it, you can feed direct battery voltage on the supply side of the solenoid and you should hear it click. Also try to test the connections between the TCC module and the engine module.

P0740=Torque Converter Clutch Circuit/Open,
not a solenoid,or tps

get your torque converter and torque solenoid checked out or replaced my civic had the same issue and that fixed the problem

Here are the DTC's for the TCC Solenoid:

DTC P0740 TCC Enable Solenoid Circuit Electrical
DTC P0741 TCC System Stuck Off
DTC P0742 TCC System Stuck On
DTC P0743 TCC Enable Solenoid Circuit Electrical
DTC P0744 Torque Converter Clutch Circuit Intermittent

Internal trans failure, Trans would have to be rebuilt.
