Yes, there is a sensor on the transmission that can cause the speedometer to stop working if it goes bad. This sensor is called the
Vehicle Speed Sensor (VSS). The VSS is responsible for sending a signal to the speedometer that indicates how fast the vehicle is traveling. If the VSS fails, the speedometer will not receive this signal and will therefore stop working.
Here are some symptoms of a bad VSS:
* The speedometer stops working.
* The odometer stops working.
* The cruise control does not work.
* The transmission shifts erratically.
If you are experiencing any of these symptoms, it is possible that the VSS has failed and needs to be replaced.
