What does code P27B0 mean?

Q: What does code P27B0 mean?

Pressure Control Solenoid K Data Incompatible. P27B0 means the transmission control module (TCM) has received data from the pressure control solenoid K circuit that falls outside the expected range or pattern, so the solenoid's feedback signal is incompatible with the commanded pressure. The computer is not necessarily seeing an open or short circuit; it is flagging that the solenoid's reported data does not agree with what the TCM expects under current operating conditions.
