How did we estimate these prices?

Jerry's experts researched and collected data from 2500+ real repair shops in all 50 states in the US, including everything from the total cost of repair services to the hourly labor cost for mechanic labor in each shop. We combined that data with our expert database of hundreds of real repair jobs, thousands of real cars, millions of real car part prices in order to best estimate the cost of each repair service. Our labor cost estimate is calculated by taking the average hourly labor rate for a certified mechanic in the US, times the number of hours it takes on average to complete a repair. We recommend you compare your local shops with Jerry and contact those shops directly to get final pricing for your vehicle.

What parts do I need for my transmission speed sensor replacement and how much do those parts cost?

You can refer to your owner’s manual or ask a mechanic to find your vehicle’s specific part requirements.
The main part you’ll need to worry about is the transmission speed sensor itself. Speed sensor costs can vary widely and could easily range somewhere between $50 and $350 or more, depending on your vehicle.
If your vehicle is still under warranty, you might not have to worry about paying for a replacement sensor out of pocket.
If you are buying the parts yourself, we recommend looking at local auto parts stores like AutoZone, Advance Auto Parts, and NAPA Auto Parts, as well as online retailers like Amazon and RockAuto. We also recommend reputable brands such as Standard Motor Products, ACDelco, and Dorman for transmission speed sensor components. However, like price, recommended brands may also vary depending on your vehicle’s specific year, make, and model.
Generally, OEM parts, such as an OEM transmission speed sensor, are designed specifically with your vehicle in mind. Of course, some manufacturers’ OEM parts may be more reliable than others.
On the other hand, you might find an aftermarket speed sensor that’s either more affordable or has a higher quality. What’s most important is that you verify the part matches the required specs for your vehicle.
You may be able to find a replacement transmission speed sensor for your vehicle at an auto parts shop like AutoZone, Advance Auto Parts, and NAPA Auto Parts or through your vehicle’s manufacturer. Online retailers like Amazon and RockAuto are also convenient options for purchasing parts.

How will a mechanic replace my transmission speed sensor?

Replacing a transmission speed sensor—sometimes referred to as a vehicle speed sensor (VSS)—can be a complicated process, so it’s better left to a certified mechanic. Here are some of the general steps a mechanic will usually take during a transmission speed sensor replacement:
  1. Preparation and inspection: Depending on the symptoms you're noticing, your mechanic will likely inspect the vehicle for any obvious signs of damage or test drive the vehicle. Then, they can raise the vehicle for a better look at your transmission.
  2. Removal and replacement: If the mechanic determines the transmission speed sensor needs replacement, they’ll remove the faulty sensor and install a new one.
  3. Refill the transmission fluid: Your mechanic will have likely drained the transmission fluid from the transmission’s input shaft and torque converter to access the sensor. After the new sensor is installed, the mechanic will refill the transmission fluid to the proper level.
  4. Quality assurance check: Before handing you back the keys, the mechanic will check over their work and possibly take another test drive to ensure the new sensor is functioning properly.

What happens if I don’t replace my transmission speed sensor?

You can usually count on having a rough driving experience with a failed transmission speed sensor—but ignoring the problem too long could damage your transmission or other parts of your vehicle.
If you notice any symptoms of a transmission speed sensor problem, don’t wait to get an inspection. A failing transmission speed sensor can lead to the following issues:
  • Rough ride, especially when shifting gears
  • Inconsistent RPM or speedometer readings
  • Check engine light illuminates
  • Cruise control won’t work

What is a transmission speed sensor?

A vehicle’s transmission speed sensors monitor the rotational speed of a manual or automatic transmission. It then relays this information to a transmission control unit (TCU) so that it can smoothly shift gears at the appropriate times.
Without a properly working transmission speed sensor, you’ll likely experience rough gear shifting that could make your car undrivable or cause expensive damage.

When should I replace the transmission speed sensor on my car?

The transmission speed sensor doesn’t typically come with regular maintenance or replacement intervals—you’ll only need to replace it if it’s not working properly. A certified mechanic can inspect your vehicle and determine whether or not you need a transmission speed sensor replacement.
The most common symptoms of a bad transmission speed sensor include:
  • Rough gear shifting: If your transmission control unit can’t communicate with your transmission speed sensor, it will become more difficult for your vehicle to switch gears as your speed changes—which can lead to a jerking, uncomfortable ride.
  • Check engine light turns on: If your vehicle’s onboard diagnostic (OBD) system detects a problem with your transmission speed sensor or related part, your check engine light might turn on as a result.
  • Cruise control won’t work: Your cruise control depends on information from the transmission speed sensor to maintain a constant speed. If your transmission speed sensor fails, you might notice that your cruise control no longer works properly.
  • Inconsistent RPM or speedometer readings: The RPM gauge on your dashboard also depends on information from the transmission speed sensor. If your RPM readings are erratic or don’t seem to be consistent with your vehicle’s actual operating conditions, it’s possible a bad transmission speed sensor could be the culprit.

How often should a transmission speed sensor be replaced?

Transmission speed sensors don’t typically require routine maintenance or replacement unless they fail prematurely. A certified mechanic can inspect your vehicle to determine whether or not your transmission speed sensor is working properly.

Can I replace my transmission speed sensor myself?

A transmission speed sensor replacement is a job best left to the professionals. It can be a difficult part to access on many vehicles, and a mechanic should inspect your vehicle to identify any other potential problems that could have similar symptoms.


When your transmission speed sensor fails, the most obvious symptom is usually rough shifting between gears. You might also notice erratic RPM readings or nonfunctioning cruise control.
A failed transmission speed sensor is a problem you don’t want to delay fixing. At best, you’ll likely experience rough vehicle rides until you replace the sensor, but at worst, you risk damaging your transmission or other parts of your vehicle. Not being able to shift your transmission gears at the right time could also potentially lead to dangerous driving situations.
A vehicle’s transmission speed sensors monitor the rotational speed of the transmission. It then relays this information to a transmission control unit (TCU) so that it can smoothly shift gears at the appropriate times.
