Get Your GM Truck or Van Back to Peak Performance
Is your trusty GM truck, van, or SUV suddenly running rough, shifting erratically, or failing to start? A faulty Powertrain Control Module (PCM) is often the culprit, acting like a confused brain for your vehicle’s engine and transmission. This can lead to frustrating downtime, poor fuel economy, and persistent check engine lights. Don’t let a bad computer sideline the vehicle you depend on. This is the reliable, straightforward solution to get you back on the road with confidence.
Common Symptoms & Your Solution

- Harsh or erratic automatic transmission shifting
- Engine stalling or cutting out unexpectedly

A Technician’s Take: As a mechanic with over 20 years on the shop floor, I’ve seen drivers waste a lot of time and money on untested junkyard computers. The problem is, an unprogrammed module is just a metal box. The real value is in the software. Every vehicle’s programming is slightly different based on its engine, transmission, and options. Our process ensures your Programmed 16263494 PCM has the correct, updated software for your specific truck or van, which is the secret to fixing the problem right the first time.
Frequently Asked Questions
Do I need to have this programmed by a dealer?
No. The main benefit of our service is that we program the module to your vehicle’s VIN before we ship it. This means it arrives ready to be installed without any need for additional, expensive dealership programming.
What information do you need from me?
After you place your order, you will need to provide us with your vehicle’s 17-digit VIN. We cannot process and ship your order without it, as it’s essential for loading the correct software onto the module.
Is this difficult to install?
For most DIYers with basic tools, this is a straightforward installation. It typically involves disconnecting the vehicle’s battery, unplugging the electrical connectors from the old PCM, unbolting it, and then installing the new one in the reverse order. Some vehicles may require a simple security relearn procedure, which can be done without special tools.
How do I know for sure that my PCM is the problem?
While the symptoms listed above are strong indicators, it’s always best to have your vehicle properly diagnosed. A professional mechanic can confirm if the PCM is faulty, often by checking for specific trouble codes (like P0601 – Internal Control Module Memory Check Sum Error) and ruling out other potential issues like bad sensors or wiring.
Will this fix my check engine light?
If the check engine light is on due to an internal failure of your original PCM, then yes, this Programmed 16263494 PCM is designed to resolve that issue. If the light is caused by another failing part on the vehicle (like an oxygen sensor or ignition coil), that part will still need to be addressed.
What’s the difference between a PCM, ECM, and ECU?
The terms are often used interchangeably. ECM (Engine Control Module) and ECU (Engine Control Unit) typically refer to a computer that only controls engine functions. A PCM (Powertrain Control Module) is a more integrated unit that controls both the engine and the automatic transmission functions, which is common in the GM vehicles this part fits.
