Is Your Truck or Van Running Rough? Get Back on the Road with Confidence.
There’s nothing more frustrating than a dependable workhorse that suddenly starts acting up. If your Chevrolet, GMC, or GM vehicle is suffering from a persistent Check Engine Light, erratic shifting, poor fuel economy, or even a no-start condition, a failing Powertrain Control Module (PCM) is often the culprit. This isn’t just an inconvenience; it’s a problem that affects your vehicle’s reliability and performance. This module is the heart of your vehicle’s operation, and we provide the direct, reliable solution to get it beating strong again.

Expert Insight: Why Fresh Software Matters
As a technician, I’ve seen countless vehicles from this era with persistent, nagging issues that even new parts couldn’t fix. Often, the root cause was a software glitch in the original PCM that GM corrected years later. When you buy a used module, you’re just getting that same old, potentially flawed software. Our process ensures your new 16263494 PCM is loaded with the most recent, stable, and efficient software available from GM. It’s like giving your vehicle’s brain a fresh start with all the lessons learned over the last two decades, ensuring a smoother, more reliable drive.
Frequently Asked Questions
Will this PCM be plug-and-play?
Yes, this module is programmed to your VIN and is ready for installation. However, on many GM vehicles of this era, you may need to perform a simple Security Relearn Procedure after installation. This procedure pairs the new PCM to your vehicle’s anti-theft system and can typically be done in your driveway with just the ignition key. Instructions are widely available online or in service manuals.
How do I provide my VIN?
After you complete your purchase, you will need to send us your 17-digit Vehicle Identification Number (VIN). We cannot ship your part until we receive this information, as it is essential for the programming process.
Is this the correct part for my vehicle?
This module replaces part number 16263494 and the other compatible numbers listed in the description. The best way to ensure compatibility is to check the part number on your vehicle’s original module. If it matches one of the numbers listed, this is the correct part for you.
What if my original part number is slightly different?
This module is a direct replacement for all part numbers listed in the compatibility section (16263494, 16265035, 8162634940, etc.). These numbers are interchangeable, and our unit will function correctly for any of them.
What tools are needed for installation?
Installation typically requires only basic hand tools, such as a socket set and ratchet, to access and unbolt the module. Always remember to disconnect the vehicle’s battery before beginning any work on the electrical system.
