P0740 on Dodge
Torque Converter Clutch Circuit Malfunction
P0740 on Dodge vehicles indicates torque converter clutch circuit malfunction. Au7o has documented this code across 1 Dodge model — most commonly on Caliber. This code indicates a malfunction in the torque converter clutch (TCC) circuit of an automatic transmission. The torque converter clutch mechanically locks the engine to the transmission at cruising speed to improve fuel economy and reduce slippage, and it is engaged by a solenoid controlled by the transmission computer. The code sets when the computer detects an electrical problem with the clutch circuit or sees that the clutch is not engaging or holding as expected. Common signs include slipping, shuddering, poor fuel economy, or stalling when coming to a stop. Typical repair costs on Dodge range from $2,000 to $4,500, depending on the specific model and root cause.
