Where is the transmission speed sensor located on a transmission?
The Vehicle Speed Sensor (VSS) is located on the right rear of the transmission near the tail shaft. Also asked, what happens when a transmission speed sensor goes bad? When there are symptoms of a bad transmission speed sensor, the powertrain control module cannot control the shifting of gears within the transmission properly.
What happens when a transmission sensor goes bad?
This may cause the transmission to shift roughly or more quickly than normal. It’s also common that a problem with these sensors can impact the shift timing, extending the interval between transmission shifts. An automatic transmission is hydraulically controlled and designed to shift smoothly.
Which is the output shaft speed ( OSS ) sensor?
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.
Can a bad speed sensor affect shift timing?
Harsh or improper shifting. Without a valid speed signal from these sensors, the PCM will not be able to correctly control the shifting of gears within the transmission. This may cause the transmission to shift roughly or more quickly than normal. It’s also common that a problem with these sensors can impact the shift timing,…
Where is the transmission shift sensor located?
It’s located in the valve body or oil pan of the transmission or transaxle. The TCM uses this sensor to monitor the temperature of the transmission fluid.
Where is Ford transmission range sensor located?
On a Ford transmission, the sensor is located on the driver side of the transmission, toward the rear of the unit. The sensor is a magnetic unit that screws into the transmission and has an electrical connector plugged into it.
Where the Heck is the transmission range sensor?
In most cases, the transmission range sensor is located on the outside of your transmission housing . One or two “wires” emanate from your gear lever and control the gears of the transmission. Instead of having a sensor directly on the gear lever (depending on the car model), the sensor is located on the transmission.
What are the symptoms of a bad transmission speed sensor?
Symptoms of a Bad or Failing Transmission Speed Sensor. Common signs include harsh or improper shifting, cruise control not working, and the Check Engine Light coming on. The transmission speed sensors are used to calculate the actual gear ratio of the transmission while in use.
How can I repair the transmission speed sensor?
Consult the repair manual for your car. Place bucket or oil drain pan underneath the sensor, there will be some oil that drains out. Disconnect the sensor from the housing on the transmission, as indicated in the repair manual for your car. Disconnect the sensor’s wire coupling.

What happens if the transmission sensor is not working?
That data, along with data from other sensors around the car, is used to set shift points, adjust engine calibrations, and even manage cruise control. If those sensors aren’t working properly, the transmission may shift roughly or sluggishly, cruise control may not work, or the speedometer may malfunction.
How much does it cost to install a speed sensor?
A sensor that rarely ever fails, but if it your vehicle is equipped with one of these and does fail expect the speedometer to fluctuate and the transmission to shift erratically. The cost of the part was 74 dollars, and took 30 minutes to install.
What does a fluctuating transmission speedometer mean?
A fluctuating speedometer may be a sign of a faulty transmission sensor. If you have a truck or SUV with enough ground clearance, you won’t need to jack up your car.
What is a speed sensor in a transmission?
The transmission speed sensor is a magnetic sensor that provides this information, allowing the transmission to shift smoothly. The sensor counts the internal number of revolutions of the transmission and transmits that information to the transmission control unit, where the data is used to determine the rotational speed.
