Q: What does code P08D9 mean?

Shift Solenoid K Intermittent. P08D9 is a generic transmission trouble code that indicates the transmission control module (TCM) has detected an intermittent fault in the circuit for shift solenoid K, which is one of the solenoids that controls gear shifts. The computer sets this code when the solenoid's electrical signal is erratic, meaning it sometimes works and sometimes does not, rather than failing completely.
