Restore Your GM Truck’s Brain and Get Back to Work
Is your trusty Chevrolet, GMC, or GM vehicle suffering from frustrating and unpredictable issues? A faulty Powertrain Control Module (PCM) can cause a cascade of problems, from a simple check engine light to a vehicle that refuses to start. This isn’t just an inconvenience; it’s a roadblock to getting your job done. This replacement PCM, compatible with service number 16265035, is the definitive solution to restore your vehicle’s reliability and performance.

Common Symptoms & Your Direct-Fit Solution
If you’re experiencing any of the following, a failing engine computer is the likely culprit:
- Persistent Check Engine Light (CEL)
- Engine stalling or cutting out while driving
- Rough or erratic idling
- Poor acceleration and loss of power
- Decreased fuel economy
- Harsh or incorrect transmission shifting
- No-start condition where the engine cranks but won’t fire
- Diagnostic Trouble Codes (DTCs) related to internal module failure (e.g., P0601, P0605)

An Expert’s Note on PCM Replacement
As a technician for over 20 years, I’ve seen countless vehicle owners chase phantom issues, replacing sensors and parts only to find the core problem was the PCM itself. A common mistake is grabbing a used module from a salvage yard. While it might have the same part number, it’s programmed for a different vehicle with different options, and it will almost never work correctly. That’s why a pre-programmed module is so critical. Getting a programmed 16265035 PCM that is already matched to your VIN is the single most effective way to guarantee a successful, one-time repair and get your vehicle back to being the reliable workhorse you depend on.
Frequently Asked Questions
Do I need to do anything after I install the PCM?
In many of these GM vehicles, you may need to perform a simple Security Relearn Procedure (also known as Passlock/Passkey relearn) to sync the new PCM with your vehicle’s anti-theft system. This procedure does not require special tools and typically involves a sequence of turning the key on and off. We include instructions to guide you through this easy process.
How do I provide you with my VIN?
After you complete your purchase, you can either add your 17-digit Vehicle Identification Number (VIN) to the ‘notes’ section at checkout, or you can simply reply to your order confirmation email with the VIN. We cannot ship your part until we receive this information.
Will this fix my transmission shifting problems?
Yes, in many cases it will. The Powertrain Control Module (PCM) controls both engine and transmission functions. Erratic shifting, getting stuck in a gear, or delayed engagement are common symptoms of a failing PCM. This module will restore proper communication and control over your transmission’s electronic solenoids.
Is this a new part?
This is a genuine, Original Equipment (OE) module that has been professionally inspected, tested, and prepared for service. We use OE hardware because it provides the best long-term reliability and perfect fitment, ensuring it performs to factory specifications once programmed for your vehicle.
My original part number is 16263494. Will this work?
Absolutely. This module is a direct, compatible replacement for all part numbers listed in the description, including 16263494, 8162634940, and others. As long as your vehicle is on the compatibility list and you provide your VIN, we guarantee it will be the correct, programmed part for your application.
