Common Symptoms & Your Solution
A faulty PCM can manifest in numerous ways, often mimicking other sensor or component failures. If you’re experiencing any of the following, a failing engine computer is a likely culprit:
- Harsh or erratic automatic transmission shifting
- Sudden drop in fuel economy
- Engine stalling, stumbling, or misfiring
- Failure to start or intermittent starting issues
- Check Engine Light (CEL) with Diagnostic Trouble Codes (DTCs) like P0601, P0602, or P0606
This pre-programmed module is engineered to resolve these issues by restoring the critical communication link between your vehicle’s engine, transmission, and other systems. By installing our Programmed 89017750 PCM, you directly address the root cause of these electronic failures and restore factory performance.

An Expert’s Note on Programming
As a technician with over 20 years of experience, I can’t overstate the importance of correct programming. The PCM is the central nervous system of your vehicle. Simply installing a used, unprogrammed module from a junkyard will not work—the vehicle won’t start due to the anti-theft system, and it won’t have the correct software for your engine, transmission, or even your tire size. Our process of using your VIN to flash the module ensures that every parameter is set exactly as it left the factory. This is the key to a successful, lasting repair, and it’s why a properly Programmed 89017750 PCM is the only reliable way to solve your vehicle’s electronic issues.
Frequently Asked Questions
What do I need to do after I place my order?
After you complete your purchase, you must provide us with your vehicle’s 17-digit VIN. You can typically find this on your vehicle’s registration, insurance card, or on the driver’s side of the dashboard visible through the windshield. We cannot program and ship your module without it.
Is this a difficult part to install myself?
For most DIY mechanics, this is a straightforward installation. The PCM is typically located in the engine bay under the battery tray or next to the airbox. The main steps are disconnecting the battery, unplugging the electrical connectors, and unbolting the old unit. After installing the new one, you will need to perform a security relearn procedure, which typically takes about 30 minutes and does not require special scan tools. Instructions can be easily found online for your specific model.
Will this computer fit my specific vehicle?
This PCM fits a very wide range of 2003-2007 General Motors trucks and SUVs. Please review the detailed fitment list on this page carefully. The best way to ensure compatibility is to match the service number from your original computer to one of the numbers listed (89017750, 12582605, 12589463, etc.).
Do I need any other parts for the installation?
No other parts are required for the installation. This is a complete, self-contained unit. You will only need basic hand tools to access and replace your old module.
What if my truck has performance modifications?
Our programming service installs the latest stock GM calibration for the VIN you provide. This programming is not intended for vehicles with significant performance modifications like aftermarket camshafts, forced induction, or non-stock injectors. It is designed to restore original factory performance and reliability.
