Is Your GM Vehicle Running Rough? Get It Back in Prime Condition.
If you’re dealing with a persistent check engine light, erratic engine behavior, stalling, or a complete no-start condition in your 2004 GM truck, van, or SUV, a failing Powertrain Control Module (PCM) is often the culprit. This isn’t just an inconvenience; it’s a critical failure that affects performance, fuel economy, and safety. This replacement module, part number 89017739, is the definitive solution to restore your vehicle’s factory performance and reliability, arriving at your door programmed specifically for your vehicle.
Common Symptoms & Your Solution
A faulty PCM can cause a cascade of frustrating issues. You might be experiencing one or more of the following:
- Check Engine Light (CEL) with diagnostic trouble codes (DTCs) like P0601, P0602, or P0606.
- Engine Stalling or Misfiring: Unpredictable stalling at stops or rough running while driving.
- No-Start Condition: The engine cranks but refuses to start.
- Poor Fuel Economy: A sudden and unexplained drop in your vehicle’s MPG.
- Erratic Automatic Transmission Shifting: Harsh shifts, delayed engagement, or getting stuck in gear.
This Programmed 89017739 PCM is the direct answer to these problems. We take the guesswork out of the repair by flashing the unit with the latest GM-approved software updates, tailored precisely to your vehicle’s Vehicle Identification Number (VIN). This ensures seamless communication between your engine, transmission, and other onboard systems, just as the manufacturer intended.

Expert Insight: The End of the Dealership Hassle
As a technician with over two decades of experience, I remember the old way of replacing an ECM. You’d install the new box, but the vehicle would be dead in the water—a ‘brick’. It would need to be towed to a dealership, where you’d pay hundreds for them to program it. Our process completely eliminates that step. By sending you a Programmed 89017739 PCM flashed to your VIN, we’re giving you the part and the dealership-level programming all in one package. It’s the most efficient way to get your truck or van back to work.
Frequently Asked Questions
What information do you need to program the PCM?
After you complete your purchase, we will need the 17-digit Vehicle Identification Number (VIN) from your vehicle. This ensures we load the exact correct software for your specific make, model, and options.
Is this a simple plug-and-play installation?
For the most part, yes. It is a direct physical replacement. However, on most GM vehicles of this era, you will need to perform a security relearn procedure (often called a CASE relearn or Passlock relearn) after installation. This syncs the new PCM to your vehicle’s anti-theft system and can typically be done without special tools. Instructions are widely available online for your specific model.
How do I find my vehicle’s VIN?
Your VIN can be found on your vehicle’s registration, insurance card, the driver’s side door jamb sticker, or on a small plate on the driver’s side of the dashboard, visible through the windshield.
Will this computer fix my vehicle’s problem for sure?
This PCM will correct any issues directly caused by a failing engine computer. If your vehicle has been properly diagnosed with a faulty PCM (e.g., with codes like P0601), this part is the correct solution. It will not fix problems related to other failed sensors or mechanical components.
What kind of warranty is included?
This unit is backed by our one-year replacement warranty, giving you confidence in your repair.
