Your search for a reliable 2006-2007 Duramax LLY ECM ends here.
Frequently Asked Questions
What is the process after I place my order?
After you complete your purchase, you will need to send us your vehicle’s 17-digit VIN. We cannot ship your part until we receive this information. Once we have your VIN, we will program the ECM with the correct GM software, prepare it for shipment, and send it to you.
Is this a simple plug-and-play installation?
This ECM is designed to be as close to plug-and-play as possible. It arrives programmed to your VIN, so no dealer tools are needed. However, you will need to perform a simple security relearn procedure (often called a VATS relearn) which takes about 30 minutes and involves turning the key. Instructions are widely available online for this process.
Will this fix my specific problem?
This module will correct any issues directly caused by a faulty ECM. While it solves the vast majority of the symptoms listed above, we always recommend a proper diagnosis by a qualified mechanic to confirm the ECM is the point of failure before ordering.
What information do I need to provide?
The only piece of information we need from you is your vehicle’s complete and accurate 17-digit VIN. This ensures we load the exact software configuration for your truck’s options and emissions systems.
How do I find my VIN?
Your VIN can be found on a metal plate on the driver’s side of the dashboard (visible through the windshield), on the driver’s side door jamb sticker, and on your vehicle’s registration and insurance documents.
Does this ECM fit my 2007 ‘Classic’ model truck?
Yes. The fitment information specifically mentions compatibility with the 2007 ‘Classic’ body style pickups (the ones with the creased door skin), which carried over the 2006 LLY engine and electronics. This is the correct part for those models.
