Are you battling a persistent check engine light, rough idling, or frustrating stalling issues in your GM vehicle? An unpredictable engine can turn any drive into a stressful gamble. It’s time to stop guessing and install a definitive solution. This Powertrain Control Module (PCM), compatible with service number 16236757, is the brain of your vehicle, and we deliver it fully programmed to your car’s specific Vehicle Identification Number (VIN), ensuring a seamless restoration of performance and reliability.
Common Symptoms & Your Solution
A failing PCM can cause a cascade of confusing problems that are often misdiagnosed. If you’re experiencing any of the following, this module is the likely solution:
- Erratic engine performance, including stalling or hesitation
- Poor fuel economy
- Failure to pass emissions tests
- Illuminated Check Engine Light (CEL) with communication-related codes (e.g., P0601, P0605)
- Harsh or incorrect transmission shifting
- Complete no-start condition where the engine cranks but won’t fire
Replacing your old module with our professionally programmed 16236757 PCM is the most effective way to resolve these issues and restore your vehicle’s factory-spec operation. We take care of the complex flashing process so you can focus on a simple installation.

Expert Insight: The Critical Role of Correct Programming
As a technician, I’ve seen countless drivers install a used computer from a salvage yard, only to find their problems get worse. A PCM isn’t just a part; it’s a component that must be perfectly matched to your car’s unique options, security system, and engine parameters. Our programmed 16236757 PCM isn’t just a replacement part; it’s a restoration of your vehicle’s electronic DNA. We ensure the software is correct, preventing issues like transmission damage, security lockouts (GM Passlock), and incorrect sensor readings that an un-programmed module would cause.
Frequently Asked Questions
What exactly does a PCM do?
The Powertrain Control Module (PCM) is the central computer that controls all aspects of your vehicle’s engine and transmission. It reads data from dozens of sensors to manage fuel injection, ignition timing, emissions systems, and automatic transmission shift points to ensure optimal performance and efficiency.
Where do I provide my vehicle’s VIN?
After you complete your purchase, you will need to send us your 17-digit Vehicle Identification Number (VIN). We cannot ship your part until we receive this information, as each programmed 16236757 PCM is flashed specifically for the vehicle it will be installed in.
Will I need to do anything after installing this part?
Yes. While the main engine programming is done for you, most GM vehicles of this era require a simple ‘security relearn procedure’ to sync the new PCM with your vehicle’s anti-theft system. This procedure typically takes 10-30 minutes and can be done without any special tools. We can provide instructions for this process.
How do I know this will fit my car?
This module is a direct replacement for service number 16236757 and the other numbers listed in the description. Please check the detailed fitment list on this page to confirm compatibility with your specific make, model, and year. Providing your VIN ensures we program it perfectly for your vehicle’s options.
Is this a difficult part to replace?
The physical replacement of the PCM is generally straightforward for someone with basic mechanical skills. It is typically located in the engine bay or under the dashboard. The most important step is disconnecting the vehicle’s battery before you begin. The real value we provide is handling the complex programming, which is the most difficult part of the job.
