Is a transmission sensor expensive?

If the transmission speed sensor is malfunctioning, it can make shifting gears difficult or impossible. Depending on the make, model, and year of your vehicle, replacing your transmission speed sensor can cost anywhere between $10 and $100.

How much does it cost to fix a transmission sensor?

The Best in Auto Repair

The average cost for transmission position sensor replacement is between $138 and $174. Labor costs are estimated between $137 and $173 while parts are priced at $0. This range does not include taxes and fees, and does not factor in your specific vehicle or unique location.

Can you replace a transmission sensor?

Diagnosing a faulty transmission speed sensor is pretty straightforward, as is replacing it, but to diagnose a problem fully, you'll need to be comfortable using a multimeter to check voltage. If not, take your car to a qualified mechanic for a proper once-over.

Can you fix a transmission speed sensor?

On some makes, one of the engine mounts may need to be removed to access the failed part. Transmission speed sensors cannot be repaired, only replaced.

What happens when your transmission speed sensor goes out?

When there's no speed signal coming from the sensors, shifting of gears will be a problem because the powertrain control module won't control them correctly. This will make the transmission not work properly. It will either shift more quickly or roughly than expected.

Symptoms of a bad speed sensor - hard shifting - transmission issues

How do I know if my transmission sensor is bad?

Common signs include harsh or improper shifting, cruise control not working, and the Check Engine Light coming on.

Can you drive a car with a bad transmission speed sensor?

While it's technically possible to operate your vehicle without a properly functioning vehicle speed sensor, it is strongly discouraged. A faulty VSS can negatively impact multiple aspects of vehicle operation—which is why it's best to replace a bad speed sensor as soon as possible.

How many sensors are on a transmission?

Typically, two sensors communicate the transmission data to the vehicle's powertrain control module. The first sensor, referred to as the input sensor, monitors the speed of the transmission's input shaft. The second sensor is the output sensor, which monitors the output shaft speed.

How much is a transmission speed sensor?

Depending on the vehicle year, make and model, a speed sensor can cost as little as $7.92 or as much as $100. For most vehicles, the cost for a speed sensor is between $25 and $45. Follow these procedures for replacing a faulty vehicle speed sensor (VSS).

Can a sensor cause transmission problems?

The Vehicle Speed Sensor measures vehicle speed. If it fails or malfunctions the automatic transmission may not operate properly. It may also cause the automatic transmission to go into failsafe mode making it appear that the problem is more severe than it actually is.

How long does it take to change a transmission range sensor?

If you get a professional to do the job, then it should take about 2 to 3 hours to replace the range sensor. It may take longer to fix if the sensor is located on the inside of the transmission box as the mechanic will have to disassemble it and put it back together.

What does a transmission range sensor do?

Transmission range sensors record the transmission speed. This information is required by the control unit to regulate the shifting pressure when shifting gears and to decide which gear needs to be engaged at which point. There are two types of transmission range sensor design: Hall generators and inductive sensors.

What is a transmission position sensor?

The transmission position sensor, also known as the transmission range sensor, is an electronic sensor that provides a position input to the Powertrain Control Module (PCM) so that the transmission can be properly controlled by the PCM according to the position commanded by the sensor.

How does a transmission speed sensor work?

The speed sensor detects a gear or target wheel in the transmission and generates an electric digital signal proportional to the speed of rotation. The transmission controls use this information to modify various transmission functions such as shift points and perform diagnostic tests.

How long do transmission speed sensors last?

There's no hard-and-fast rule to help you predict how long your wheel speed sensor is going to last. Unlike a brake light switch or brake caliper that can last as long as your vehicle, you can expect your transmission speed sensor to last between 30,000 and 50,000 miles.

What sensor can cause a transmission to slip?

The Turbine Shaft Sensor measures input shaft speed. The PCM uses the information provided by the TSS to determine whether or not the transmission is slipping. When it fails it usually results in shift timing problems. Depending on the manufacturer, it can cause multiple shift-timing and shift-feel problems.

Can a weak battery cause transmission problems?

A weak battery or low battery voltage can cause the transmission to enter into fail safe mode. This will cause a loss of power because the transmission will be locked in third gear.

What happens if you don't replace speed sensor?

When the sensor is broken, it causes the entire system to be disabled because it can't function without the proper data. A disabled ABS system can even impact other safety mechanisms, such as electronic stability control and traction control.

Can a transmission speed sensor cause no start?

Since any engine requires the correct air to fuel ratio and ignition timing to start, having a faulty sensor that can't adjust these symptoms on the fly can cause the engine to not start.

Does speed sensor affect acceleration?

If you notice that your car is hesitating when you try to accelerate, it could be due to a faulty speed sensor. This symptom can also be caused by a number of other problems, so it's important to have your car checked out by a mechanic.
