Transmission Speed Sensor: Description and Operation
Transmission Output Speed Sensor
The speed sensor is located in the overdrive gear case. The sensor is positioned over the park gear and monitors transmission output shaft rotating speed.
Speed sensor signals are triggered by the park gear lugs as they rotate past the sensor pickup face. Input signals from the sensor are sent to the
transmission control module for processing. The vehicle speed sensor also serves as a backup for the transmission speed sensor. Signals from this sensor
are shared with the powertrain control module.
