Get Your GM Workhorse Back on the Job
Is your truck or van suffering from frustrating and unpredictable issues? A faulty Powertrain Control Module (PCM) can bring your work to a grinding halt with problems like a persistent check engine light, poor engine performance, erratic shifting, or even a no-start condition. This isn’t just an inconvenience—it’s costing you time and money. It’s time for a reliable, permanent solution that gets you back on the road with confidence.
Common Symptoms & Your Solution
If you’re experiencing any of the following, a failing PCM is the likely culprit:
- Engine stalling or cutting out unexpectedly
- Rough or inconsistent idling
- Harsh or delayed transmission shifting
- No communication with scan tools
- Diagnostic Trouble Codes (DTCs) like P0601, P0602, or P0606
- Vehicle won’t start despite a good battery and starter

Expert Insight: The Power of Proper Programming
As a technician with over two decades of experience, I’ve seen countless issues arise from improperly matched engine computers. On these classic GM Vortec engines, the PCM is the absolute brain of the operation. It controls everything from fuel mixture and spark timing to transmission shift points. Using a generic, non-programmed module is a recipe for disaster. Our process ensures your new Programmed 16265035 PCM has the exact software calibration your vehicle needs to operate as the engineers intended, resolving complex electronic issues that a simple parts swap can’t fix.
Frequently Asked Questions
How do I provide my VIN number?
After you complete your purchase, you will need to send us your 17-digit VIN. You can typically add it as a note during checkout or reply to your order confirmation email. We cannot ship your part until we have this information.
Is this part difficult to install?
Installation is straightforward for anyone with basic mechanical skills. The PCM is usually located in the engine compartment. Simply disconnect the negative battery terminal, unplug the electrical connectors from the old module, unbolt it, and install the new one in its place. Then reconnect everything. The most important part is ensuring the battery is disconnected before you begin.
Will I need to do anything after installation?
For many vehicles, this module is plug-and-play. However, some GM vehicles from this era require a security relearn procedure (often called a CASE relearn or Passlock relearn) to sync the new PCM with your vehicle’s anti-theft system. This is a simple procedure that typically involves turning the key on and off in a specific sequence and does not require special tools.
What if this doesn’t fix my problem?
While this Programmed 16265035 PCM resolves the vast majority of electronic control issues, it’s crucial to ensure your vehicle’s underlying mechanical and electrical systems (like wiring and sensors) are in good condition. Proper diagnosis is key. This part is a high-quality component designed to fix a faulty module, not other vehicle problems.
Is this a new or a used part?
This is a high-quality, inspected, and tested component that has been prepared for service. It is programmed with the latest software and is guaranteed to function correctly upon installation.
