Mercedes Automatic TransmissionTCM Cloning
This Mercedes case study shows automatic transmission control module cloning on a supported VGS-FDCT / TC1766 unit. The workshop process involved reading and transferring EEPROM and FLASH data, preparing the replacement module and verifying communication before the unit was returned for installation.
Transmission-control-module cloning is a programming and data-transfer service. Mechanical gearbox faults, hydraulic faults and the physical condition of customer-supplied donor modules remain separate from the cloning procedure and are assessed independently where required.

Mercedes VGS-FDCT transmission control module cloning workflow.
Real workshop media showing the donor and original TCM assemblies, direct programming connection and data-reading stage. The monitor taskbar icons have been obscured for privacy while the technical programming screen remains visible.

EEPROM & FLASH data reading
Controlled programming session used to read the supported VGS-FDCT control unit data before the cloning and replacement-module transfer process.

Original & replacement TCM units
The two transmission-control assemblies are prepared side by side so the original data can be transferred to the compatible replacement unit under controlled workshop conditions.

TCM programming connection

Diagnostic-led Mercedes gearbox electronics support.
This case study demonstrates the type of Mercedes automatic transmission TCM cloning, VGS-FDCT programming and gearbox-control-module data work carried out at SG-Tronic Motorsport in Stourbridge near Birmingham. Compatibility depends on the module part number, hardware and software version, original data condition and the state of the donor or replacement unit.
