This torque converter does actually consists of transmission fluid, which helps the engine to move forward. For the torque converter to activate, there is a torque converter solenoid controlling it.

If the circuit to this solenoid fails, the p code may be stored. The most common problem you will notice when the P appears is a check engine light or gearbox light on your dashboard. You will most often not have any shifting or drivability problems, but it can be noticeable in some cases. The P error code is triggered when there is a problem in the circuit to the Torque converter clutch TCC solenoid.

By not repairing the P code, you may also cause other transmission problems in the long run. The most common mistake of the P is to think there is a problem with the torque converter itself and maybe replace it.
