Is Your Trusty GM Truck or Van Suddenly Unreliable?
There’s nothing more frustrating than turning the key on your work truck or family SUV and being met with a sputtering engine, a check engine light that won’t quit, or a complete no-start condition. These classic GM vehicles are known for their durability, but when the central computer—the Powertrain Control Module (PCM)—starts to fail, it can cause a host of confusing and debilitating problems. This isn’t just an inconvenience; it’s a loss of the reliability you depend on. You need a solution that’s straightforward, effective, and gets you back on the road without the exorbitant cost and hassle of a dealership visit.

Expert Insight: The Critical Role of VIN Programming
Many people are tempted to grab a used computer from a salvage yard, thinking it’s a cheap fix. This is a critical error. The PCM in your GM vehicle is tied to the specific VIN and its security system (like GM’s Passlock or VATS). Installing a module from another vehicle without proper programming will result in a no-start condition 100% of the time. Our service completely bypasses this issue. By flashing the module with your vehicle’s VIN and the latest GM calibrations before it ships, we deliver a true plug-and-play solution that saves you time, money, and the immense frustration of a failed repair.
Getting your vehicle back to its dependable self is simple. After placing your order, just provide us with your VIN, and we’ll handle the complex programming. You’ll receive a module that’s ready to be installed, allowing you to quickly restore the performance and peace of mind you’ve been missing. This is the smart, professional way to solve your engine computer problems and keep your GM vehicle working hard for years to come. With a properly functioning and Programmed 16263494 PCM, you can get back to work and life with confidence.
Frequently Asked Questions
Do I need to do anything after I install this PCM?
In most cases, you will need to perform a simple security relearn procedure. This can typically be done without any special tools and involves a sequence of turning the key on and off. We include instructions for this common procedure to make your installation as smooth as possible.
How do I provide my vehicle’s VIN?
After you complete your purchase, you can send us a message with your 17-digit VIN. You can find your VIN on your vehicle’s dashboard (visible through the windshield), on the driver’s side door jamb sticker, or on your vehicle’s registration and insurance documents.
Is this a brand new part?
This is a high-quality, OEM-grade component that has been thoroughly inspected and tested to ensure it meets or exceeds original factory specifications. It is then programmed with fresh, vehicle-specific software to provide lasting reliability.
What if my original part number isn’t an exact match to 16263494?
This module is compatible with several interchangeable part numbers, including 16265035 and 8162634940. Please check the detailed fitment list on this page. As long as your vehicle’s year, make, and model are listed, this programmed module will be the correct replacement.
Will this fix my transmission shifting problems?
In many GM vehicles of this era, the PCM controls both the engine and the transmission. If your shifting issues, such as harsh shifts or delayed engagement, are caused by faulty electronic signals from the computer, this replacement module can absolutely solve the problem.
Why is a programmed PCM better than a used one from a junkyard?
A used, un-programmed PCM will not start your vehicle due to the anti-theft system. Our service programs the module to your specific VIN, making it ready for your vehicle. Additionally, we load the latest GM software updates, which can correct factory bugs and improve performance and efficiency—benefits you won’t get from an old, used part.
