Important Service Information
This is strictly a cloning service—you must supply both the original and the replacement TCU.
If your vehicle has mechanical gearbox issues (not purely module-related), this service may not address them.
Ensure both units are securely packaged and clearly labelled with your order number, name and contact details.
If either unit is severely damaged, unreadable or previously tampered with, we will contact you before proceeding.
