Ultimate Guide: How to Reset the Transmission Control Module in Mercedes Vehicles (1996-2016)

If you own a Mercedes-Benz manufactured between 1996 and 2016 with either a five-speed or seven-speed transmission, you may encounter issues with gear shifts and transmission performance over time. Luckily, there's a simple procedure to reset the Transmission Control Module (TCM) that can help optimize your car's performance.

Please note that this procedure is not a remedy for serious transmission problems or a way to clear the check engine light. Instead, it resets the TCM's adaptive shift learning, which can improve overall transmission performance.

Resetting the Transmission Control Module (TCM)
Follow these steps carefully to reset the TCM in your Mercedes-Benz:

Step 1: Prepare Your Vehicle

Turn the key to the 'On' position (the second click) until all the lights on the dashboard illuminate.

Step 2: Press and Hold

Press the gas pedal all the way down, including passing the kick-down switch, and hold it for a duration of 10 seconds.

Step 3: Turn Off and Release

After holding the gas pedal for 10 seconds, turn the key back to the 'Off' position and release the gas pedal.

Step 4: Wait Patiently

This is the crucial part of the process. Do not perform any actions inside the car such as opening doors, fiddling with accessories, using your phone, or reading a book. Simply wait for a full two minutes.

Resetting the Transmission Control Module in your Mercedes-Benz from 1996 to 2016 can help optimize your transmission's performance. It's a relatively simple procedure that anyone can follow. Remember that this reset is not a fix for serious transmission issues but a way to improve shift adaptation. If you continue to experience problems, it's advisable to consult a professional mechanic.
