Restore Your GM’s Core Performance and Reliability
Is your trusty GM truck, van, or SUV suddenly giving you headaches? Unpredictable stalling, a persistent check engine light, poor fuel economy, or harsh transmission shifts can be incredibly frustrating. These aren’t just annoyances; they’re often symptoms of a failing Powertrain Control Module (PCM), the central computer of your vehicle. Instead of chasing endless repairs or facing a costly trip to the dealership, get the definitive, plug-and-drive solution that restores your vehicle’s factory-spec operation.
Common Symptoms of a Failing PCM & Your Direct Solution
If you’re experiencing any of the following issues, a failing computer is the likely culprit. This module is the solution for a faulty original unit, correcting problems such as:
- Check Engine Light (CEL) with communication-related codes (e.g., P0601, P0605, P0606)
- Engine stalling or cutting out intermittently
- No-start condition where the engine cranks but won’t fire
- Poor engine performance and reduced power
- Noticeably worse fuel mileage
- Erratic or harsh automatic transmission shifting
- Failure to communicate with OBD-II scan tools
This replacement programmed 16263494 PCM is your direct path to resolving these issues. We take the guesswork out of the equation by pre-programming the module to your vehicle’s specific Vehicle Identification Number (VIN), ensuring it works seamlessly right out of the box.

An Expert’s Note on These GM Computers
As a technician with over two decades of experience, I’ve seen countless GM trucks and vans from this era. They are legendary workhorses, but their electronics are now reaching an age where failure is common. The PCM is the brain, and when it starts to fail, it can create bizarre, phantom problems that are a nightmare to diagnose. Drivers often replace sensors and parts unnecessarily, chasing a ghost that lives inside the computer. Installing a properly programmed 16263494 PCM isn’t just a repair; it’s like giving your vehicle a clean bill of health, wiping the slate clean of those frustrating electronic gremlins and restoring the solid, dependable performance these trucks are famous for.
Frequently Asked Questions
What information do you need from me after I order?
After you complete your purchase, we simply need your 17-digit Vehicle Identification Number (VIN). We will contact you for this information. This allows us to program the module specifically for your vehicle’s configuration.
Will I need to do any extra programming after installation?
No. The module arrives fully programmed and ready for installation. However, some GM vehicles of this era may require a simple security relearn procedure (for VATS/Passlock) which takes about 30 minutes and requires only the ignition key. We provide easy-to-follow instructions for this process.
How do I find my vehicle’s VIN?
Your VIN can be found in several places: on a metal plate on the driver’s side of the dashboard (visible through the windshield), on the driver’s side door jamb sticker, and on your vehicle’s registration and insurance documents.
Is this a guaranteed fix for my vehicle’s problem?
This module will correct any and all issues originating from a faulty PCM. While it is a common point of failure, we always recommend that a proper diagnosis is performed to confirm the PCM is the root cause of your issue before purchasing.
What’s the difference between a PCM, ECM, and ECU?
The terms are often used interchangeably. ECU (Electronic Control Unit) is a generic term. ECM (Engine Control Module) typically controls only engine functions. A PCM (Powertrain Control Module), like this unit, is more comprehensive and manages both the engine and the transmission, which is standard for most of the compatible vehicles.
