Your Truck is Your Livelihood. Let’s Get It Back to Work.
When your Silverado, Sierra, or Savana van is down, every hour counts. A faulty Engine Control Module (ECM) can bring your entire operation to a halt, causing frustrating no-start conditions, poor performance, and confusing check engine lights. This isn’t just an inconvenience; it’s a threat to your schedule and your bottom line. We understand that you need a reliable, no-nonsense solution that works right out of the box. This is the definitive fix to get your dependable workhorse back on the road and earning its keep.
Common Symptoms & Your Solution
If your truck is experiencing any of the following issues, a failing engine computer is the most likely culprit. This module is the direct solution for:
- Complete no-start or intermittent starting problems
- Poor engine performance, reduced power, or erratic idling
- Harsh or incorrect shifting from the Allison transmission
- Check Engine Light (CEL) with communication-related Diagnostic Trouble Codes (DTCs) like U0100, P0601, or P0606
- Inability for a scan tool to communicate with the engine computer
- Unexplained electrical issues or injector driver module (FICM) faults
By replacing your old unit with our professionally programmed 2006-2007 Duramax LLY ECM, you’re not just buying a part; you’re restoring the brain of your vehicle’s powertrain, ensuring all components work in harmony as the factory intended.

Expert Insight: More Than Just an Engine Controller
On these Duramax-powered trucks, the ECM does more than just manage the engine. It’s in constant communication with the Transmission Control Module (TCM) for the Allison transmission. When an ECM begins to fail, it often sends corrupt data, leading to a host of shifting problems that can be misdiagnosed as an internal transmission failure. Our programming process ensures that the crucial communication link between your new 2006-2007 Duramax LLY ECM and your TCM is restored to factory specifications, protecting your transmission and saving you from costly, unnecessary repairs.
Frequently Asked Questions
How do I provide my VIN number?
After you complete your purchase, simply reply to your order confirmation email with your 17-digit Vehicle Identification Number (VIN). You can also add it to the ‘notes’ section during checkout. We cannot ship your part until we receive the VIN.
Is any additional programming required after installation?
No, this ECM comes fully programmed and ready for installation. However, on some vehicles, a security relearn or crankshaft position sensor (CASE) relearn procedure may need to be performed with a capable scan tool for optimal performance. This is a standard procedure when replacing this component.
Will this fix my specific check engine light codes?
This module is a common fix for internal processor failure codes (like P0601, P0606) and communication loss codes (U-codes). If you have codes related to specific sensors, you should verify those sensors and their wiring are in good condition before replacing the ECM.
My old computer has a different part number on it. Will this work?
Yes. This 2006-2007 Duramax LLY ECM is a direct replacement for a range of part numbers, including 19260753, 12588335, 12606126, and others listed in the fitment guide. As long as your vehicle is a 2006-2007 GM truck or van with the LLY diesel, this is the correct part.
What does the warranty cover?
The one-year replacement warranty covers any failure of the module itself. If the unit fails within one year of the purchase date, we will provide a replacement unit. The warranty does not cover issues caused by external vehicle faults, such as shorted wiring or faulty sensors.
