This is a check engine light code that could potentially make your vehicle difficult, or impossible to drive altogether. The P code means that your transmission control module, the computer tasked with controlling your automatic transmission, has registered a problem with the torque converter clutch circuit. In other words, your torque converter is not functioning normally, and the cause is most likely a mechanical issue of some sort. One positive thing about this particular error is that its causes are usually benign. The torque converter is a crucial piece of any powertrain that uses an automatic transmission. The torque converter works by utilizing transmission fluid to transfer the power from the engine to the transmission. It consists of a pump , a reactor , and a turbine. The pump and turbine look very similar as they both feature metal fins fanned all around their circumference. The main difference between these two components is the orientation of the fins and the components they are attached to. The pump is driven by the engine, while the turbine drives the transmission. The whole system works as follows — the engine spins the pump, which spools up the fluid inside the torque converter. The fluid is then passed through the reactor where its direction of flow is optimized before it hits the turbine.
