About Gear Box ECUs

The Mercedes-Benz gear box ECU (sometimes known as a Transmission Control Unit) is an essential part of the gear box in an automatic vehicle, and monitors and controls the gear changes and transmission. This electrical part communicates with the engine ECU using a series of sensors that are positioned at strategic points in the vehicle. Using the information given to it by the sensors and the engine ECU it calculates when to change the vehicle’s gears to improve vehicle performance and minimise fuel consumption. These sensors tell the Mercedes-Benz gear box ECU what speed the vehicle is driving at, whether it is driving uphill or downhill, the temperature of the oil and the amount of torque generated by the torque converter.

Some vehicles have a combined Mercedes-Benz gear box ECU and engine ECU, known as a powertrain control module (PCM).

Damage to the Mercedes-Benz gear box ECU is likely down to the solenoids – magnetic wire coils that transport electric current. If your vehicle experiences problems with the Mercedes-Benz gear box ECU you may first notice a warning code displayed in your vehicle. If ignored, the gear box can fail resulting in an inability to change gears.

Mercedes-Benz trivia

  • That new car smell is always a delight, but a Mercedes owner gets to choose that smell. Perfume specialist Marc vom Ende created four different car smells for Mercedes Benz, called Sports Mood, Freeside Mood, Downtown Mood, and Nightlife Mood. They all smell a bit leathery.
  • If you thought self-driving cars were all about Tesla, then it might surprise you to know that Mercedes Benz made an autonomously driving vehicle as early as 1995. It didn't gain popularity, but it became the foundation of the modern driving technology found in every Mercedes Benz.
  • 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.
  • Karl Benz might have patented the design of his Motorwagen in 1886, but it was his wife who jumped behind the wheel first for a quick (as quick a 0.9hp will deliver) 120-mile tour through the countryside of Germany. Poor Karl didn't even know!
  • 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.
