What does code P27AE mean?

Q: What does code P27AE mean?

Pressure Control Solenoid H Data Incompatible. P27AE indicates that the transmission control module (TCM) has received data from the pressure control solenoid H circuit that is outside the expected range or inconsistent with other sensor inputs. The TCM compares the solenoid's commanded state with its actual feedback signal and sets this code when the two do not agree, pointing to a communication or signal integrity problem rather than a simple open or short circuit.
