The generic description for the P error code is Torque converter clutch TCC solenoid — circuit intermittent. To understand what this code means, we must shortly explain the anatomy behind this assembly. The torque converter clutch is a mechanical coupling inside the automatic transmission that connects it to the engine. Its job is to, when possible, create a link that overrides the torque converter and reduces transmission losses.

We recommend Torque Pro. In simple terms, a torque converter is a hollow drum that is attached to the engine, and encloses a turbine that is attached to the transmission, with no direct contact between the drum and the turbine. Put in another way, this means that since some transmission fluid is forced through the small gap between the vanes on the drum and those on the turbine as the outer drum rotates, the fluid that is lost in this way cannot contribute to the transmission of power from the engine to the transmission. In short, this means that automatic applications without torque converter lockup clutches are less fuel-efficient than applications that do have torque converter lockup clutches.

This code is triggered when the Powertrain Control Module PCM detects an electrical fault in the torque converter clutch solenoid circuit. The torque converter clutch solenoid is responsible for controlling the amount of torque that is transferred between the engine and transmission during gear changes.
