Restore Peak Performance to Your GM Vehicle
Is your reliable GM truck, van, or SUV suddenly plagued with frustrating issues? An intermittent check engine light, poor fuel economy, or harsh shifting can sideline the vehicle you depend on. The Powertrain Control Module (PCM) is the brain of your vehicle’s operation, and when it fails, it can cause a cascade of problems. This is your direct-fit, professionally programmed solution to get your vehicle running right again.
Common Symptoms & Your Solution
A failing engine computer can be difficult to diagnose, often mimicking other component failures. If you’re experiencing any of the following, a faulty PCM is a likely culprit:
- Check Engine Light with communication-related Diagnostic Trouble Codes (DTCs) like P0601, P0604, or P0606.
- No-Start Condition where the engine cranks but won’t fire up.
- Poor Fuel Economy and a noticeable loss of engine power.
- Erratic or Harsh Shifting from the automatic transmission.
- Stalling or Misfiring for no apparent reason.
This isn’t just a replacement part; it’s a complete solution. We program this 16263494 PCM to your vehicle’s unique VIN, loading it with the latest GM software updates. This ensures it communicates perfectly with your vehicle’s existing systems right out of the box, eliminating the need for an expensive trip to the dealership for programming.

From the Technician’s Bench
“I’ve seen it a dozen times. A customer comes in with a work van that’s shifting hard. They’ve already replaced the transmission solenoids, but the problem persists. The issue wasn’t mechanical; it was electronic. The original PCM was sending faulty signals. Installing a properly programmed 16263494 PCM didn’t just fix the shifting—it smoothed out the idle and improved the throttle response. Don’t chase ghosts in the machine; address the source of the problem and get your vehicle back to earning its keep.”
Frequently Asked Questions
Why do you need my VIN?
Your Vehicle Identification Number (VIN) is essential because it allows us to load the exact, correct software for your vehicle’s specific configuration, including engine, transmission, and emissions options. This makes the installation process simple and ensures the part works correctly right away.
Is this part difficult to install?
For most of the compatible vehicles, the PCM is located in the engine bay and is held in by a few bolts and electrical connectors. Installation is typically straightforward for a DIYer with basic tools. After installation, you may need to perform a security relearn procedure, which can often be done without special tools. We recommend disconnecting the battery before starting.
Will this fix my check engine light?
If the check engine light is caused by an internal fault in your old computer (like a P0601 code), this replacement 16263494 PCM is the correct solution. However, you should always ensure that any other codes related to sensors or wiring are addressed first, as the PCM can only operate with good information from the rest of the vehicle.
What happens after I place my order?
After you complete your purchase, you will need to provide us with your 17-digit VIN. You can typically add this in the notes section at checkout or reply to your order confirmation email. We cannot program and ship your module without it.
Does this module come with keys?
No, this is only the engine control module. Your vehicle’s existing keys will need to be relearned to the replacement PCM. This is a standard anti-theft security step. For many of these GM vehicles, the procedure can be done at home and involves turning the key in the ignition in a specific sequence.
