Restore Your Vehicle’s Brain and Get Back on the Road
Is your truck or van suffering from frustrating, hard-to-diagnose issues? A failing Powertrain Control Module (PCM) can cause everything from a persistent check engine light and poor fuel economy to harsh shifting and even a no-start condition. Stop chasing symptoms and replace the core of the problem. This Engine Control Module is the reliable, straightforward solution to restore your vehicle’s performance and your peace of mind. It arrives pre-programmed specifically for your vehicle, taking the guesswork and expensive dealership programming out of the equation.
Common Symptoms & Your Solution
If you’re experiencing any of the following, a faulty PCM is the likely culprit. This unit is the definitive fix for:
- Erratic or harsh transmission shifting
- Engine stalling, stumbling, or misfiring
- Failure to start or intermittent starting issues
- Poor fuel mileage and engine performance
- Check Engine Light with communication-related Diagnostic Trouble Codes (DTCs) like P0601, P0602, P0605, or P0606
- Other modules (like the TCM or BCM) not communicating with the engine computer
This programmed 89017733 PCM is engineered to resolve these issues by providing a stable, correctly calibrated control unit for your engine and transmission.

Expert Insight: Why VIN Programming is Non-Negotiable
Many people are tempted to grab a used computer from a salvage yard, hoping for a cheap fix. This almost never works. Your vehicle’s PCM is part of a complex network that communicates with other modules using a unique Vehicle Identification Number (VIN). An unprogrammed or incorrectly programmed module will cause communication conflicts, security system lockouts (preventing the vehicle from starting), and incorrect engine/transmission operation. Our VIN-flashing service ensures this programmed 89017733 PCM integrates seamlessly with your vehicle, just like the original, saving you from days of frustration and additional diagnostic costs.
Frequently Asked Questions
How do I provide my VIN number?
After you complete your purchase, you will need to send us your 17-digit Vehicle Identification Number (VIN). We will provide clear instructions on how to send it to us. We cannot ship your part until we receive and validate your VIN.
Is any additional programming required after installation?
In most cases, no. Because we pre-program the module to your VIN, it is ready for 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 are widely available online for this simple procedure.
Will this fix my specific problem?
This programmed 89017733 PCM is a direct solution for a failed module. While it resolves the common symptoms listed, it’s crucial to ensure your vehicle has been properly diagnosed. The module cannot fix underlying mechanical issues, faulty sensors, or wiring problems.
Is this a used part?
This is a high-quality, inspected, and tested component that has been verified to meet or exceed original equipment performance. It is then loaded with fresh, vehicle-specific software for reliable operation.
Where is the PCM located on my vehicle?
The location varies. On many GM trucks like the Sierra and Silverado, it’s under the hood on the driver’s side, often under the battery tray. On Express and Savana vans, it’s typically in the LH rear of the engine compartment. Always consult a repair manual for your specific model to confirm the location before beginning work.
