Is Your GM Truck or SUV Running Rough?
If you’re dealing with frustrating issues like a no-start condition, erratic engine behavior, poor fuel economy, or a persistent check engine light, a failing Powertrain Control Module (PCM) is often the culprit. Your vehicle’s computer is its brain, and when it starts to fail, it can cause a cascade of problems that leave you stranded and stressed. Don’t let a faulty computer sideline your reliable workhorse. This is the straightforward, professional solution to get your vehicle back in top form.

A failing PCM can manifest in many ways. You might be experiencing:
- Harsh or failed shifting

Expert Insight: The Junkyard Gamble vs. A Sure Bet
As a technician, I’ve seen it countless times: someone grabs a used computer from a salvage yard to save a few bucks. The problem is, that computer is programmed for a different vehicle’s VIN and options. It won’t work correctly without being flashed by a dealer, which can cost hundreds and often results in compatibility headaches. Our Programmed 16263494 PCM completely bypasses that gamble. You get a reliable component, loaded with the correct, updated software for your truck, saving you immense time, money, and frustration.
Frequently Asked Questions
How does the programming process work?
It’s simple. After you place your order, you provide us with your vehicle’s 17-digit VIN. Our technicians use this VIN to access the official GM database and load the exact software and calibrations your vehicle requires. We then ship the ready-to-install module directly to you.
Do I need to do anything after installing it?
Yes. After installation, you will need to perform a security relearn procedure (also known as a Passlock or anti-theft relearn). This process syncs the new PCM with your vehicle’s anti-theft system and can typically be done in your driveway with just the ignition key. Instructions are readily available online for your specific model.
Is this part compatible with my vehicle?
This module is a direct replacement for part numbers 16263494, 16265035, and others. Please review the detailed fitment list on this page to confirm it matches your specific year, make, and model. Programming to your VIN guarantees it works with your vehicle’s options.
What is a “CASE Relearn” and is it required?
A CASE (Crankshaft Angle Sensor Error) relearn may be required to prevent a P1336 trouble code. This procedure calibrates the PCM to the specific signal from your crankshaft position sensor. Most professional scan tools can perform this function in a few minutes. While the vehicle will often run without it, we recommend performing it for optimal performance.
What if I provide the wrong VIN?
The VIN is critical for correct programming. Please double-check the VIN from your driver’s side dashboard or door jamb sticker before sending it. An incorrect VIN will result in a module that will not function in your vehicle, so accuracy is essential.
