DESCRIPTION The transmission revolution sensor (NT) detects the input shaft rotation speed and sends it to the ECM. Based on the transmission revolution sensor (NT) signal and the transmission revolution sensor (NC) signals, the ECM controls engine torque and shift timing. Based on the input shaft r ...
