After vehicle sits over night transmission shifts properly for about the first two minutes of driving each morning then you can feel transmission slam into fail safe mode. vehicle seems to be stuck in third gear and is very slow off the…
How does the Transmission Control Module control the torque converter?
The transmission control module has detected a fault with the circuit that operates the torque converter clutch solenoid. We will consider the TCM the controller for the sake of this article although it may be controlled through the PCM/ECM, consult factory wiring diagrams to determine which system is being used.
What does the code p0740 mean on a torque converter?
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. You need to find some measure values for your specific car and transmission model, though.
When do I get the trouble code on my torque converter?
Every vehicle built since 1996 returns this generic trouble code when a problem is detected with the torque converter clutch circuit, however, modern vehicles now determine when to give this code based on other information as well such as throttle position, engine load, car speed etc.
What is the code for torque converter clutch solenoid?
Code P0740 indicates that the control module detects an electrical problem with the torque converter clutch solenoid or the solenoid’s circuit. Note: Although code P0740 is a generic code specified by the Society of Automotive Engineers (SAE), the code’s definition may vary depending on the vehicle manufacturer.
What does the p0740 code on a PCM mean?
What Does the P0740 Code Mean? The P0740 code indicates that the powertrain control module (PCM) has observed an unusual behavior within the torque converter clutch circuit.
