What does code P27E0 mean?

Q: What does code P27E0 mean?

Pressure Control Solenoid T Control Circuit High. P27E0 indicates that the transmission control module (TCM) has detected an abnormally high voltage on the control circuit for pressure control solenoid T, which is one of the hydraulic pressure regulators inside the transmission valve body. The TCM commands a specific current to the solenoid to regulate clutch apply pressure, and when the feedback voltage on the circuit exceeds the expected range, the TCM stores this code and typically defaults to a limp-home strategy.
