Frequently Asked Questions
Use the module label and complete part number for final service confirmation before shipping.
Can you program every GMC ECU or TCU listed here?
The catalog identifies GMC module families we can review, but final approval depends on the complete part number, hardware and software identification, vehicle details and requested work. Send the module label before shipping.
What information is needed for a GMC programming request?
Provide the vehicle year, model and VIN when requested, plus clear photos of the complete module label and the service you need. For a replacement module, include both the original and replacement part numbers.
Can I mail in a GMC module from outside California?
Yes. Pro Programming USA provides nationwide mail-in service. Start an order before shipping so the module, vehicle information and requested work are connected to the correct service request.
Does a programmed GMC module arrive ready to install?
Some supported applications can be prepared for installation, while others still require vehicle-side coding, adaptations or relearns. We confirm the expected next steps after reviewing the exact application.
