Summary
Automatic Transmission Speed Sensor
An Automatic Transmission Speed Sensor monitors the input and output shaft speeds of the vehicle’s transmission to ensure proper gear shifting. It may also send this information to the powertrain control module so it can regulate other drivetrain and vehicle functions.
Automatic Transmission Speed Sensors are located on the transmission, typically near the input or output shafts.
If your vehicle is experiencing the following, it may be time to replace your Automatic Transmission Speed Sensor:
- Delayed or hard shifting
- Check engine light stays on
