Q: What does code P27A7 mean?

Pressure Control Solenoid A Data Incompatible. P27A7 means the transmission control module (TCM) has received data from the pressure control solenoid A circuit that falls outside the range or pattern the module expects for the current operating conditions. The TCM compares the solenoid's commanded current or duty cycle against the resulting hydraulic pressure response, and it sets this code when the two do not agree.
