Gearbox TCU Cloning
Clone original TCU software for plug-and-play replacement.
Gearbox TCU Cloning (Transmission Control Unit Copying)
When a gearbox TCU fails, replacing it usually means reprogramming it to match your car.
Our Service
We clone the original TCU's software and data onto a replacement unit. This allows:
- Plug-and-play TCU replacements
- Gearbox swaps or upgrades
- Fault recovery without main dealer costs
This service ensures smooth gear shifts, correct communication with the ECU, and no immobiliser issues.
Frequently Asked Questions
Cloning copies the entire software image from your old TCU to the new one, making it a direct 'plug and play' replacement.
Usually, we just need the original and replacement TCU units. However, bringing the car allows us to test the replacement fully.
Most TCU cloning jobs are completed within 1-2 hours. The process involves reading the data from your original unit, transferring it to the replacement, and verifying the clone.
We can clone TCUs for automatic, DSG, CVT, and semi-automatic gearboxes across most makes including BMW, Mercedes, VW, Audi, Ford, Land Rover, and many more. Contact us with your vehicle details for confirmation.
