DTC codes / P27xx · Transmission / P27F3
P27F3 indicates that the transmission control module has detected an excessively high temperature for clutch B, which is one of the internal clutch packs in an automatic or dual-clutch transmission. The computer compares the clutch temperature estimate, often derived from fluid temperature and operating conditions, against a calibrated threshold and sets this code when the clutch is running too hot.
Guidance is general and written for all OBD-II vehicles. Exact tests and values vary by model, so confirm the fault before replacing parts.
