Restore Peak Performance to Your GM Truck or SUV
Is your truck or SUV suffering from frustrating issues like a persistent check engine light, erratic transmission shifting, stalling, or even a no-start condition? These are classic signs of a failing Powertrain Control Module (PCM). Don’t let a faulty computer keep your reliable vehicle sidelined. This direct-fit PCM is the definitive solution to restore the performance, efficiency, and dependability you count on every day.
Common Symptoms & Your Solution
A failing PCM can cause a wide range of confusing problems that can be difficult to diagnose. If you’re experiencing any of the following, a faulty module is the likely culprit:
- Persistent Check Engine Light (CEL) with codes like P0601, P0606, or other internal processor faults.
- Harsh or Erratic Shifting: The PCM controls transmission line pressure and shift points. Failure can lead to clunky shifts or getting stuck in gear.
- Engine Stalling or Misfiring: Inaccurate fuel or spark commands from a bad PCM can cause poor engine performance.
- Poor Fuel Economy: When the engine isn’t running efficiently, your fuel mileage will suffer.
- No Communication: If your scan tool can’t communicate with the engine computer, the module itself has likely failed.
This Programmed 89017750 PCM is the answer. We take the guesswork out of the repair by flashing the unit with the latest official GM software, tailored specifically to your vehicle’s VIN. This ensures perfect compatibility and function right out of the box.

An Expert’s Note on Drivability
As a technician, I’ve seen countless hours and dollars wasted chasing what seems like a mechanical issue. A customer once brought in his ’06 Silverado 2500 with a persistent, random misfire and a transmission that just didn’t feel right. He had already replaced plugs, wires, and a coil pack. After diagnosing, we found the injector driver circuit within the original PCM was failing intermittently. Installing a properly Programmed 89017750 PCM didn’t just fix the misfire—the updated software we installed also corrected the harsh 2-3 shift he had learned to live with. This isn’t just a part; it’s a comprehensive fix that restores the vehicle’s core operating logic.
Frequently Asked Questions
What is the difference between a PCM, ECM, and ECU?
These terms are often used interchangeably. PCM (Powertrain Control Module) is most accurate for these GM vehicles as it controls both the engine and the transmission. ECM (Engine Control Module) and ECU (Engine Control Unit) typically refer to a computer that only controls the engine.
How do I provide my VIN for programming?
After you complete your purchase, you will need to send us your 17-digit Vehicle Identification Number (VIN). We cannot ship your part until we receive this information, as the programming is essential for the part to function in your vehicle.
Will I need to do anything after I install it?
Yes. While the main programming is done, you will need to perform a security relearn procedure (often called a CASE relearn or Passlock relearn) so the module can sync with your vehicle’s anti-theft system. This procedure is simple, requires no special tools, and instructions can easily be found online for your specific model.
Is this a guaranteed fix for my vehicle’s problem?
This module will fix any issue directly caused by a faulty PCM. However, it’s crucial to ensure your vehicle has been properly diagnosed. This part will not fix underlying mechanical problems, sensor failures, or wiring issues. We highly recommend a professional diagnosis before ordering.
How do I find my part or service number?
The service number is printed on the label of your original computer module. This listing is compatible with several numbers, including 89017750, 12582605, 12589463, and 12602802. Matching one of these numbers confirms compatibility.
