About ECU Transmission Control Units

The Mercedes-Benz ECU transmission control unit is an on-board computer which electronically controls the transmission of the vehicle. TCUs can be separate from, or in this case, attached to the ECU. The Mercedes-Benz ECU Transmission Control unit contacts sensors that are placed around the vehicle to receive data in order to accurately calculate when to change gears and which gear to use as well as improve fuel economy and drive quality.

These sensors include the vehicle speed sensor, the wheel speed sensor, the throttle position sensor, the turbine speed sensor and the transmission fluid sensor. The TCU also uses data sent from the ECU. This controls and maintains the efficient running of the engine as well as scanning for any abnormalities in its function.

If a Mercedes-Benz ECU transmission control unit begins to fail, you may notice a loss of power, error message or difficulty in changing gears. This problem can be intermittent at first, and can sometimes be rectified temporarily by turning off your car and turning it back on again after a short while. Ultimately though, any damage to a Mercedes-Benz ECU transmission control unit will need to be repaired to correct the fault.

Mercedes-Benz trivia

  • Mercedes Benz cars have always been a big part of the Jurassic Park films, but the first movie went all out, with the stars emerging from a red Mercedes GLE Coupe before walking down the red carpet. Mercedes cars are also used throughout the film franchise.
  • Karl Benz founded the famous car company. He is not only credited as the maker of the world's first practical motorcar but also has the distinction of being the first person ever issued with a driving license (local citizens kept complaining about the noise and smell of his Motorwagen, and so he needed written permission to drive it).
  • In 1924, Mercedes Benz became the first car manufacturer to include brakes on all four of a car's wheels. Not long after, in 1931, they also added suspension springs to the corners of the Mercedes Benz 170.
  • We all recognise that distinctive Mercedes logo, but did you know that the three points of the star represent air, land, and water? There was a point where they considered adding another point to represent space, but they decided against it in the end.
  • Most people think of silver when they think of a Mercedes, but that iconic colour was an accident. Just before a race in 1934, the white-painted W25 was found to be 1kg over the weight limit. The paint was quickly removed, the weight limit reached, and the car won the race.
