OBD-II Code P2767 means that the Input/Turbine Speed Sensor 'B' Circuit is not sending any signal to the Transmission Control Module (TCM). This sensor is responsible for telling the TCM how fast the engine is spinning so the correct gear can be engaged. When the TCM receives an inaccurate signal from this sensor, it can't properly shift the vehicle from gear to gear as the vehicle needs to change speed and rates of acceleration.
