A RUNDOWN ON MERCEDES-BENZ TRANSMISSION CONTROL MODULES

WHAT IS A MERCEDES-BENZ TRANSMISSION CONTROL MODULE?

A Mercedes-Benz Transmission Control Module (TMC) is an electronic component and the driving force behind the Mercedes-Benz automatic transmission. These highly complex computerized components allow automatic vehicles to control gear shifts according to data received from various input sensors and other control modules within your vehicle.  

WHAT IS THE PRIMARY FUNCTION OF THE MERCEDES-BENZ TRANSMISSION MODULE?

Mercedes-Benz transmission control modules were designed for countless reasons. Enhanced performance, fuel economy and seamless gear shifting. They are, after all, produced with precision German engineering, and are backed by decades of technological developments. However the primary function of this component is to ensure high SHIFT QUALITY!

Automatic Mercedes-Benz transmissions should engage smoothly and firmly when the gear selector is placed into Drive. Any shifting issues should be addressed by a reputable Mercedes-Benz specialist to accurately assess any problem. Whilst there could be many possibilities to shifting issues, limp mode is a safety measure that many are unfamiliar with.

WHAT IS MERCEDES-BENZ LIMP MODE?

Limp mode is a safety feature specifically designed by the manufacturers to detect irregular signals that are not within the computer’s programmed specifications. This safety feature will disable the Mercedes-Benz transmission control module, preventing gear shifts and causing the transmission to default to a single gear. This should sound a warning bell that your transmission is in limp mode!

MOST COMMON CAUSES OF MERCEDES-BENZ TRANSMISSION LIMP MODE?

The most notable causes of Mercedes-Benz transmission limp mode have been mentioned above, however, shifting issues in most modern Mercedes- Benz transmission which are electronically controlled could lie with a faulty transmission control module or faulty electronics such as speed sensors, solenoids and selector sensors that are directly connected to the transmission control module.
