Why does the p0740 have a torque converter clutch?
The TCC “locks” the drivetrain, which allows for a true mechanical connection between the transmission and the engine. In effect, this allows an automatic transmission to function like a manual transmission at certain speeds and engine loads, and eliminates all slipping from the transmission. The symptoms of P0740 vary greatly.
What does p0740 mean on a Dodge Ram?
P0740 is one of the most common transmission trouble codes. It means that the Ram ‘s computer has detected that there is an issue with the torque converter clutch (TCC) solenoid circuit. P0740: Torque Converter Clutch Circuit Malfunction
What happens when your transmission is too dirty?
Slipping Gears. A dirty transmission may cause a lack of hydraulic power, much the same as not having enough transmission fluid will cause. In order to stay in the appropriate gear, the transmission must develop enough pressure. When a transmission is too dirty, contaminants may interfere with the flow of transmission fluid that helps with this.
When does the solenoid set the p0740 code?
On most vehicles, the module will set a P0740 code when it detects an electrical fault with the TCC solenoid or the TCC control circuit. Also, as was mentioned, on some vehicles, the code may set when the TCC’s performance is out of range due to a mechanical problem.
What does p0740 mean on a Transmission Control Module?
The P0740 indicates that the transmission control module recognizes a problem with the torque converter clutch circuit. Automatic cars usually use a converter to transfer the power between the engine and the transmission. This torque converter does actually consists of transmission fluid, which helps the engine to move forward.
Is there a problem with the torque converter clutch solenoid?
The most common mistake of the P0740 is to think there is a problem with the torque converter itself and maybe replace it. The p0740 code clearly states a problem with the electrical circuit to the torque converter clutch solenoid and not a problem with the torque converter itself. Diagnosing the P0740 is often pretty straightforward.
When to use the p0741 clutch solenoid code?
Applying the TCC improves fuel economy, reduces engine speed, and lowers the temperature of the transmission fluid. The control module may store a P0741 code when it detects the TCC is slipping, operating erratically, or not engaging.
