What does p0744 mean on a torque converter?
Note that code P0744 rarely indicates a faulty transmission, or a general failure of mechanical components in the transmission or torque converter.
What does the p0744 code on a PCM mean?
If the PCM has stored the P0744 code, it means that there was an intermittent abnormality detected in the torque converter clutch circuit.
What are the possible causes of Nissan p0744?
P0744 NISSAN Possible Causes 1 Faulty torque converter clutch solenoid valve 2 Torque converter clutch solenoid valve harness is open or shorted 3 Torque converter clutch solenoid valve circuit poor electrical connection 4 Low transmission fluid level 5 Dirty transmission fluid
How is the torque converter clutch solenoid valve activated?
The Torque Converter Clutch (TCC) solenoid valve is activated, with the gear in D4, by the Transmission Control Module (TCM) in response to signals sent from the vehicle speed and the Engine Control Module (ECM). Lock-up piston operation will then be controlled.
When do I get a p0744 on my car?
The P0744 is detected when A/T cannot perform lock-up even if electrical circuit is good. The Torque Converter Clutch (TCC) solenoid valve is activated, with the gear in D4, by the Transmission Control Module (TCM) in response to signals sent from the vehicle speed and the Engine Control Module ( ECM ).

What causes torque converter clutch solenoid code p0740?
An error occurred while retrieving sharing information. Please try again later. Code P0740 can be caused by anything from a faulty solenoid to a costly internal transmission problem. As such, there isn’t a single, guaranteed fix for the code.
What are the symptoms of a p0744 trouble code?
The symptoms of the P0744 code can vary. There may be no detectable symptoms at all beyond the illumination of the Check Engine Light. However, symptoms could be as dire as the total failure of the torque converter clutch to disengage.
How much does it cost to diagnose Nissan code p0744?
Labor: 1.0 The cost of diagnosing the P0744 NISSAN code is 1.0 hour of labor. The auto repair labor rates vary by location, your vehicle’s make and model, and even your engine type. Most auto repairs shops charge between $75 and $150 per hour. When is the P0744 NISSAN code detected?
What happens when torque converter solenoid valve is activated?
When the torque converter clutch solenoid valve is activated, the torque converter lockup clutch will engage creating a 1 to 1 RPM ratio between the transmission input shaft and the rotational speed of the torque converter. Lock-up operation, however, is prohibited when A/T fluid temperature is too low.
