This is a comprehensive TCU (Transmission Control Unit) coding suite for Mercedes-Benz specialists, combining two essential and powerful tools to cover multiple generations of automatic transmissions. The primary software in this package is Mercedes Gear Tool v2.11, a dedicated editor for older EGS52 controllers, complemented by the previously discussed VGSNAG2 Manager for modern TCUs.
Main Tool: Mercedes Gear Tool v2.11 (for EGS52)
This expert utility by Sergey Klenov is designed specifically for editing and creating the coding string for EGS52 transmission control units. These controllers are found in the legendary and extremely common 5-Speed 5G-Tronic (722.6) and the first generation of 7-Speed 7G-Tronic (722.9 VGS1) transmissions.
• Primary Purpose: Allows for the adaptation of new or used EGS52 TCUs to a vehicle by modifying the coding. This is essential when replacing the controller.
• Key Functions: Provides full control to edit the hydraulic variant, mechanical variant, torque converter (TQ) settings, and various driving/shifting programs.
• User-Friendly Interface: The tool expertly decodes the long, complex hex coding string into a clear, editable list of parameters, making the process much easier and safer than manual hex editing.
The Complete Coding Solution
This package is so powerful because it provides a tool for nearly every Mercedes automatic transmission you will encounter:
• Mercedes Gear Tool (EGS52): Use this for the 5-Speed (722.6) transmission, found in millions of vehicles like the W211, W220, Sprinter, as well as many Chrysler, Dodge, and Jeep models that used this gearbox.
• VGSNAG2 Manager (VGS2/3 & NAG3): Use this companion tool for the modern 7-Speed (722.9) and 9-Speed (9G-Tronic) transmissions found in most Mercedes cars from the mid-2000s to the present day.
By having both tools, you are equipped to handle TCU coding and replacement for almost the entire modern history of Mercedes-Benz.
System Compatibility
This software has been fully tested and is confirmed to be working perfectly on Windows 10 LTSC (2019).
