Is Your GM Truck or SUV Running Rough?
Are you battling a persistent check engine light, erratic shifting, or a frustrating no-start condition? A failing Powertrain Control Module (PCM) is often the hidden culprit, acting as the brain of your vehicle’s engine and transmission. When it fails, it can cause a cascade of problems that are difficult to diagnose. This is your direct-fit, reliable solution to restore your vehicle’s performance and get you back on the road with confidence.
Common Symptoms & Your Direct Solution
A faulty PCM can manifest in many ways. You might be experiencing poor fuel economy, a rough idle, hesitation during acceleration, or even random stalling. Often, you’ll see Diagnostic Trouble Codes (DTCs) like P0601, P0602, or P0606, which point directly to an internal computer fault. Instead of guessing with other parts, this Programmed 89017750 PCM is the definitive fix.

Frequently Asked Questions
How does the programming process work?
After you complete your purchase, you will need to provide us with your vehicle’s 17-digit VIN (Vehicle Identification Number). Our technicians use this VIN to load the latest, most up-to-date GM-certified software and calibrations specifically for your vehicle’s engine, transmission, and options. The module then ships to you ready to be installed.
Do I need to do anything after installing this PCM?
In most cases, this is a plug-and-play installation. However, some vehicles may require a security relearn procedure (often called a CASE relearn or anti-theft relearn), which can typically be done without special tools. Instructions for this simple procedure are widely available online for your specific model.
How do I find my service number to confirm compatibility?
Your original PCM will have a sticker on it containing the service number. It is crucial to match one of the compatible service numbers listed in our description (e.g., 89017750, 12582605, etc.) to ensure you are ordering the correct hardware for your vehicle.
What happens if I provide the wrong VIN?
The VIN is critical for correct programming. An incorrect VIN will result in the PCM having the wrong software, which can lead to a no-start condition, poor performance, or damage to other components. Please double-check your VIN from your driver’s side door jamb or dashboard plate before sending it to us.
Will this fix my vehicle’s specific problem?
This PCM will correct any issues directly caused by a faulty engine computer. While it solves a wide range of common symptoms, it’s essential to have your vehicle properly diagnosed to rule out other potential causes, such as bad sensors or wiring problems.
