What is the name of the transmission speed sensor?

There are generally two speed sensors that work in conjunction to provide accurate transmission data to the vehicle’s powertrain control module. The first is known as the input shaft speed (ISS) sensor. As described, this sensor is used to monitor the speed of the transmission’s input shaft. The other sensor is the output shaft speed (OSS) sensor.

What causes the speedometer to go off when you change a tire?

Changing the stock parts, including the vehicle’s tires, can throw off the speedometer calibration; larger tires cause the speedometer to read a speed slower than the vehicle’s actual speed while smaller tires cause the speedometer to read a speed faster than the vehicle’s actual speed.
