This repair takes on average 0.90h - 1.10h for a mechanic to complete. A wheel speed sensor replacement swaps out one of your wheel speed sensors, also known as an ABS monitor. A wheel speed sensor measures the rotational speed of your wheel using magnets, then sends the data to your braking system.

Do wheel speed sensors affect transmission?

In certain vehicles, a faulty ABS or wheel speed sensor can lead to the improper operation of the transmission which is reason enough why some cars do go into limp mode, to prevent potential damage to the transmission.

What causes speed sensors to fail?

Over time, the transmission speed sensor can go bad due to wiring issues or just outright failing due to it constantly being used every time you are driving your vehicle. If the sensor is magnetic, it can go bad from iron sticking to the tip of the sensor, which will cause an inaccurate reading.
