Where is the speed sensor on a car?

The vehicle speed sensor (VSS) is also commonly referred to as a transmission speed sensor or output shaft speed sensor. It is a small device—typically mounted somewhere on the transmission—that determines how fast your vehicle is going by measuring the rotation of a toothed wheel on a shaft inside the transmission.

What are the two sensors that monitor transmission speed?

The first is known as the input shaft speed (ISS) sensor. As described, this sensor is used to monitor the speed of the transmission’ input shaft. The other sensor is the output shaft speed (OSS) sensor. If either of these two sensors falls out of alignment or experiences electrical issues, it impacts the operation of the entire transmission.
