DTC codes / P27xx · Transmission / P2701
P2701 indicates that the transmission control module has detected an abnormal apply time or performance for friction element 'B', which is a clutch or band inside the automatic transmission. The computer monitors the time it takes for the element to engage or disengage and sets this code when the measured time falls outside the expected range, often due to hydraulic or mechanical wear.
Guidance is general and written for all OBD-II vehicles. Exact tests and values vary by model, so confirm the fault before replacing parts.
