DTC codes / P27xx · Transmission / P2747
P2747 means the transmission control module (TCM) is not receiving a usable signal from the intermediate shaft speed sensor 'B' circuit, so it cannot confirm the actual speed of the intermediate shaft. The computer detects this when the sensor circuit stays at a fixed voltage or produces no pulses while other speed sensors show the vehicle is moving.
Guidance is general and written for all OBD-II vehicles. Exact tests and values vary by model, so confirm the fault before replacing parts.
