Trouble code P0740 means: Torque Converter Clutch Solenoid Circuit
A torque converter clutch solenoid valve circuit controls the operation of the torque converter clutch in an automatic transmission. The solenoid valve regulates hydraulic pressure to engage or disengage the clutch, allowing for a direct connection between the engine and transmission. This improves fuel efficiency and performance by reducing engine load during steady driving conditions. When the solenoid malfunctions, it can lead to issues such as slipping or harsh shifting in the transmission.
