Transmission Speed Sensor

Transmission speed sensors are essential components in a vehicle's transmission system. They perform a contactless scan of a gear or trigger wheel in the transmission and generate an electronic digital signal that is proportional to the speed of rotation.

There are two main types of speed sensors that work together to provide accurate transmission data to the vehicle's engine control module or transmission control unit. The first is known as the input shaft speed (ISS) or primary sensor, which monitors the speed of the transmission's input shaft. The second sensor is called the output shaft speed (OSS) or secondary sensor.

If either of these two sensors falls out of alignment or experiences electrical issues, it can significantly affect the operation of the entire transmission.
