What does fault code p0741 in OBD II mean?
What Does Code P0741 Mean? OBD II fault code P0741 is most commonly defined as “ Torque Converter Clutch Circuit Performance” or sometimes as “Torque Converter Clutch- Stuck Off”, and is set when the PCM (Powertrain Control Module) detects an abnormal electrical value in the torque converter clutch control circuit.
What are the symptoms of a p0741 solenoid?
Some possible symptoms could include the following- 1 Excessive transmission slippage under hard acceleration. 2 Transmission overheating. 3 Harsh shifting. 4 Increased fuel consumption. 5 Depending on the application, other transmission or torque converter clutch codes may be present along with P0741.

What causes low transmission fluid level in p0741?
P0741 Possible Causes Low transmission fluid level Dirty transmission fluid Faulty torque converter clutch solenoid valve Torque converter clutch solenoid valve harness or connectors Torque converter clutch solenoid valve circuit is open or shorted
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.
When is the p0741 code detected?
When is the P0741 code detected? The torque converter clutch 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.
How is the torque converter clutch solenoid valve activated?
The torque converter clutch 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.

What does the p0741 diagnostic trouble code mean?
What the P0741 code means. The Powertrain Control Module (PCM) will set the P0741 diagnostic trouble code when it notices a difference between the rotational speed of the torque converter and the transmission input shaft that is greater than 200 revolutions per minute (RPM).
How much does it cost to repair a p0741 Chevy?
The cost to diagnose the P0741 CHEVROLET code is 1.0 hour of labor. The auto repair’s diagnosis time and labor rates vary by location, vehicle’s make and model, and even your engine type. Most auto repair shops charge between $75 and $150 per hour.
The torque converter clutch 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.
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.
What the P0741 code means. The Powertrain Control Module (PCM) will set the P0741 diagnostic trouble code when it notices a difference between the rotational speed of the torque converter and the transmission input shaft that is greater than 200 revolutions per minute (RPM).
How is the solenoid of a torque converter controlled?
The TCC solenoid is normally controlled by a duty cycle to engage a more comfortable torque converter cluch engagement. To test if the TCM is actually sending the signal, a graphing multimeter set to duty cycle or a digital storage oscilloscope will be required as well.
How to check power side of DTC solenoid?
Check for voltage on the power side circuit of the TCC solenoid or at the wire harness connector at the TCM with the DVOM set to volts scale, positive lead at the wire being tested and the negative to a known good ground with the vehicles key on/engine off, battery voltage should be present.
What does the DTC code p0740 stand for?
What Does the P0740 Code Mean? Diagnostic trouble code (DTC) P0740 stands for “Torque Converter Clutch Solenoid Circuit/Open Circuit Malfunction.” On most vehicles, it indicates that the control module perceives an electrical fault with the torque converter clutch solenoid or the solenoid’s circuit.
