Get Your GM Truck or Van Back on the Job
Is your reliable workhorse suddenly anything but? If you’re dealing with a persistent Check Engine Light, erratic shifting, a rough idle, or even a no-start condition, a failing Powertrain Control Module (PCM) is often the culprit. Your truck or van is a tool for your trade, and downtime is not an option. This Powertrain Control Module is the definitive, professional-grade solution to restore your vehicle’s performance and dependability, getting you back on the road and back to work without a costly trip to the dealership.
Common Symptoms of a Failing PCM & Your Direct Solution
A faulty engine computer can cause a wide range of frustrating issues that can be difficult to diagnose. If your vehicle is experiencing any of the following, this module is your solution:
- Persistent Check Engine Light (CEL): Especially for codes like P0601, P0602, P0606, or other internal controller errors.
- Poor Engine Performance: Noticeable loss of power, hesitation during acceleration, or decreased fuel economy.
- Erratic Transmission Shifting: Harsh shifts, delayed engagement, or getting stuck in gear.
- Engine Stalling or Misfiring: The engine may stall intermittently or run rough for no apparent reason.
- No-Start Condition: The engine cranks but refuses to start, even with a good battery and starter.
This isn’t just a replacement part; it’s a complete solution. We use your vehicle’s Vehicle Identification Number (VIN) to pre-program this programmed 89017749 PCM with the latest, most stable software updates from General Motors.

An Expert’s Note on VIN Programming
As a technician with over 20 years on the floor, I’ve seen countless people try to save a few bucks by grabbing a used computer from a salvage yard. It almost never works. Modern GM vehicles use a sophisticated anti-theft system (VATS/Passlock) that links the PCM to your specific key and vehicle. A module from another vehicle will trigger this system, resulting in a no-start condition. Our VIN programming service handles this complex handshake ahead of time, ensuring the programmed 89017749 PCM is accepted by your vehicle’s security system, making the installation process as straightforward as possible.
Frequently Asked Questions
What exactly does the PCM do?
The Powertrain Control Module (PCM) is the central computer of your vehicle. It controls all aspects of engine and transmission function, including fuel injection, ignition timing, emissions systems, and shift points, to ensure optimal performance, fuel economy, and low emissions.
How do I provide my VIN?
After you complete your purchase, you will need to send us your vehicle’s 17-digit VIN. You can typically find this on your driver’s side dashboard (visible through the windshield), on the driver’s door jamb sticker, or on your vehicle’s registration and insurance documents.
Is this module difficult to install?
For most of the compatible trucks and vans, the PCM is located in the engine bay and is held in by a few bolts and has several large electrical connectors. Installation is generally straightforward for a DIYer with basic mechanical skills. Always disconnect the battery before beginning the installation. The key is that our pre-programming of this programmed 89017749 PCM removes the most difficult step: the software setup.
Will I need to perform any other procedures after installation?
In some cases, a security relearn procedure may be necessary to fully sync the new PCM with your vehicle’s anti-theft system. This is typically a simple process that involves cycling the ignition key and can be done without any special tools. We can provide instructions if needed.
