It’s a significant problem if it begins to malfunction, and should be dealt with accordingly. Speculation has been rife about gearbox issues and malfunctioning ABS sensors. An appropriate query would be, “Can a malfunctioning ABS sensor create transmission issues?” Until now, we haven’t talked about ABS sensors, so let’s go into that now. A car’s parts, on the other hand, are practically all linked together. As soon as one of these components begins to fail, the rest will soon follow suit, resulting in a catastrophic failure of the vehicle.

Understanding ABS Sensors

It is also known as a Wheel Speed Sensor or Anti-lock Brake Sensor. The ABS monitors and measures the wheel’s rotational speed, then transmits this information to the ECM (Engine Control Module). The dashboard of your automobile has a large number of inactive icons that only come to life when there is a problem with the vehicle. You have a malfunctioning wheel speed sensor if you see the ABS sensor message on your dashboard (not responding). A severe problem, as most modern cars’ systems are automated.

Consequently, it is possible that the entire system will cease to function if a single component fails. The ABS sensor and the gearbox system are examples of this. In the following section, we’ll describe how the ABS influences transmission.

Can ABS Sensor Cause Transmission Issues?

As a matter of fact, ABS might lead to gearbox problems. As you can see, there is a clear link between these two systems. Wheel speed sensors are now standard on nearly all new vehicles. The sensors’ job is to keep tabs on wheel speed and relay that information to the ABS. In addition, the sensors transmit information about the vehicle’s wheel speed to the traction control system. In addition to traction control and ABS, the ECU is in charge of both of these systems.

Thus, the ECU initiates the ABS or traction control to restore control of the vehicle when it receives unusual speed information in certain scenarios. These sensors, however, are prone to malfunction and can deliver incorrect data to the ECU over time. As a result, your transmission system may be receiving inaccurate signals from the ABS, which could cause transmission issues. ABS, on the other hand, is known to cause problems with transmissions. You should send your automobile to a professional if the ABS light appears on your dashboard; it might be a bad wheel speed sensor or something else.

Your car’s dashboard ABS light can be troubleshooted by you to find out what caused the light to come on. A multimeter is required for ABS system troubleshooting.

What Causes the ABS Light to Show on the Dashboard?

You’re seeing the ABS light since the system has recognized a fault; consequently, the light is to alert you to a critical problem with a component attached or integrated to your car’s Anti-Brake Lock System (ABS). If the ABS light comes on while you’re driving, you don’t have to immediately slam on the brakes. After arriving at your destination, undertake a troubleshoot to find out what the problem is. A defective wheel speed sensor is most likely to blame for a false signal. Among the other possibilities are:

The accumulation of metallic dust, filth, or debris owing to exposure to particular hostile conditions. Damaged or blown wires or fuses (wires that connect the ABS controller and sensors)
Wheel-speed sensor damage or road dirt on the sensor
The controller for the ABS has stopped working.

What Are The Signs of a Bad ABS Sensor?

If you experience any of the following symptoms, you should have your ABS system inspected right away. Not as quickly as usual do you appear to be using your brakes.

When driving on ice, you don’t appear to have complete command of the vehicle.

Where to Find ABS Sensors in a Car?

When an automobile has four wheels, it naturally comes with four ABS sensors mounted on each wheel (also called wheel speed sensors). These sensors are attached to the wheels and transmit data to the ABS computer to monitor speed.

How To Fix Faulty ABS Sensors

Repairing problems with ABS is best left to a professional mechanic. If you have a high level of technical expertise, it won’t be too difficult to follow the DIY instructions provided by the ABS system.


So, can a malfunctioning ABS sensor cause a transmission issue? It’s possible, yes. Anti-lock brakes (ABS) can interfere with the shifting of your vehicle’s transmission. Keep an eye on your car’s dashboard, and don’t ignore any warning signs it may give you. Consider purchasing a troubleshooting gadget that will allow you to test your car’s systems more quickly.
