Mercedes-Benz Transmission Speed Sensor – OE 0125424217

Ensure smooth gear transitions and protect your drivetrain with our premium Transmission Speed Sensor. Specifically designed for Mercedes-Benz applications, this sensor provides the ECU with critical real-time data regarding transmission input/output speeds.

A faulty sensor can lead to “limp mode,” harsh shifting, or incorrect speedometer readings. Our manufactured replacement is built to solve these issues, offering a high-reliability alternative to expensive dealership parts without sacrificing performance.

Performance Benefits:

  • Precision Hall-Effect Technology: Utilizes advanced magnetic sensing for accurate pulse readings even at low speeds.

  • Extreme Temperature Resistance: Designed to operate flawlessly within the high-heat environment of a Mercedes-Benz gearbox.

  • Corrosion-Resistant Housing: Features a high-grade polymer shell to prevent oil and moisture ingress.

  • Perfect Calibration: Matches the electrical resistance and signal frequency of the original Benz factory part.


Application & Compatibility

This sensor is widely used across various Mercedes-Benz platforms, particularly in heavy-duty and commercial sectors.

  • Mercedes-Benz Actros/Antos/Arocs: Commonly used in automated manual transmissions (AMT).

  • Mercedes-Benz Atego/Axor: Essential for electronic gearbox control units.

  • Mercedes-Benz Buses: Fits various O-Series and Citaro models.
