Q: What does code P27CC mean?

Pressure Control Solenoid R Intermittent. P27CC indicates that the transmission control module (TCM) has detected an intermittent fault in the electrical circuit for pressure control solenoid R, which is one of several solenoids that regulate hydraulic pressure inside the automatic transmission. The TCM monitors the solenoid's current draw and response time, and when the signal drops out or behaves erratically for a fraction of a second, it logs this code and may command a fail-safe mode.
