Restore Your Vehicle’s Performance and Reliability
Is your Buick Lucerne, Chevy Impala, or other GM vehicle running rough, stalling unexpectedly, or showing a persistent Check Engine Light? A failing Powertrain Control Module (PCM) is often the culprit behind these frustrating and complex issues. This genuine GM PCM, part number 19210736 (interchangeable with 12605843), is the definitive solution to get your vehicle running like new again. We take the guesswork out of the repair by pre-programming the unit specifically for your car using your VIN. This isn’t just a part; it’s a complete, ready-to-install fix that restores communication between your engine and transmission, bringing back the smooth, reliable performance you depend on.
Common Symptoms & Your Solution
If you’re experiencing any of the following, a faulty PCM is the likely cause. This module is the solution for:
- Unexplained Check Engine Lights (CEL)
- Engine stalling, sputtering, or misfiring
- Poor fuel economy
- Harsh or erratic transmission shifting
- No-start conditions where the engine cranks but won’t fire

Expert Insight: Why VIN Programming is Non-Negotiable
As a veteran technician, I’ve seen countless drivers buy used modules online only to find they don’t work. The reason is simple: a PCM isn’t a one-size-fits-all part. It’s programmed with specific data for the original vehicle’s engine, transmission, and options. Without proper programming to your VIN, the module won’t communicate correctly, leading to performance problems or even a no-start situation. Our service eliminates that risk. We ensure the Programmed 19210736 PCM you receive is a perfect digital match for your car, saving you time, money, and headaches.
Frequently Asked Questions
How do I provide my VIN number?
After you complete your purchase, you will need to send us your 17-digit Vehicle Identification Number (VIN). We cannot ship the module until we have this information, as the programming is a critical part of your order.
Is this a new part?
No, this is a high-quality, used OEM computer that has been carefully removed from a salvaged vehicle, inspected, and fully tested to ensure it is ready for programming and installation in your car.
Will I need to do anything else after installing it?
The module arrives ready to install. However, many GM vehicles from this era have an anti-theft system (Passlock/VATS) that may require a simple security relearn procedure after installation. This procedure can typically be done without any special tools and instructions are widely available online.
How can I be sure this part fits my vehicle?
Please review the detailed fitment list on this page. The most important step is to match the part number (19210736 or 12605843) to your original module. Providing your VIN for programming ensures it will function correctly for your specific model and options.
What does the one-year replacement warranty cover?
The warranty covers the module itself. If the unit fails within one year of the purchase date, we will provide a replacement part. It covers defects in the part but does not cover issues caused by improper installation or other failing components on the vehicle.
