TCU & Gearbox Module Cloning and Support

Replacing a gearbox control module? ECU Logic UK checks whether your original TCU data can be transferred to a compatible replacement and whether coding or adaptation is needed. Support is available for owners and garages across the North East.

TCU replacement and cloning

A TCU, transmission control module or gearbox control module can hold software, calibration, identity and adaptation-related data. When supported, cloning may transfer required information from the original into a compatible donor. It is one possible route, not a universal answer.

The same connector or similar casing does not prove that the hardware, software or internal data structure is compatible. Original and donor part numbers, software references and manufacturer supersessions are reviewed before work.

Pricing

TCU or gearbox module work

Quote required

Price depends on module type, communication, access, donor compatibility, data condition and whether vehicle-side coding, adaptation or calibration is needed.

See module pricing policy

Work route

Module-only work and vehicle-side requirements

Module identification

Clear labels and complete vehicle details help establish whether the proposed donor is a realistic match before it is purchased or fitted.

Data transfer

A communicating original may offer a supported read route. A non-communicating or damaged unit requires individual assessment and may not contain recoverable data.

Coding and adaptation

Some replacements may need coding, variant configuration, adaptations, relearns or calibration with the vehicle present. Cloning does not remove every vehicle-side step.

Useful details, if available

  • Registration or VIN, make, model and year
  • Gearbox type and transmission code if known
  • Full diagnostic scan, codes and symptoms
  • Original TCU label photographs
  • Donor label photographs
  • Whether the original communicates
  • Previous gearbox or electrical work

Start with what you have. We can ask for any further information needed.

Diagnosis before replacement

Transmission codes do not automatically prove internal TCU failure. Supply voltage, power, ground, wiring, network communication, sensors, actuators, fluid or mechanical gearbox faults can produce module-related symptoms. Diagnostic testing may be needed before a replacement route is accepted.

Final requirements, risks and responsibility for fitting and vehicle testing are confirmed before work begins.

Assess a donor TCU before fitting

Send your vehicle details and symptoms. Include a diagnostic scan and photographs of both module labels if available.

Price and scope are confirmed before booking. Additional work is agreed separately.
