- ✔ Engine stalling, stumbling, or hesitating during acceleration
- ✔ Harsh or erratic transmission shifting
- ✔ Complete no-start or intermittent starting issues

Guided Installation to Restore Peace of Mind
You don’t need to be a master mechanic to complete this job. With basic tools and a little patience, you can have your car back on the road in under an hour. Follow these simple steps for a successful installation.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery before beginning any electrical work.
- Locate the Old PCM: On most compatible models, the PCM is found in the engine bay, often near the battery, air filter box, or on the firewall. It’s a metal box with several large electrical connectors.
- Disconnect and Remove: Carefully unplug the wiring harnesses from the old module. There are typically release tabs that need to be pressed or lifted. Once disconnected, unbolt the module from its mounting bracket.
- Install the New Module: Mount your new, pre-programmed PCM securely in place of the old one. Reconnect the wiring harnesses, ensuring they click firmly into place.
- Power Up: Reconnect the negative battery terminal. The vehicle may require a security relearn procedure, which typically involves turning the key to the ‘ON’ position for 10-15 minutes. Consult your owner’s manual for specific instructions.
- Start and Verify: Start the engine and let it run. The check engine light should be off, and the engine should run smoothly. Your repair is complete!
From a Mechanic’s Notebook
“I had a customer with a Chevy Cobalt who was at his wit’s end. The car would stall randomly at red lights, and two different shops couldn’t give him a straight answer, just a huge estimate. He was ready to sell the car for scrap. We identified a failing PCM. Instead of a costly dealer part, we ordered one of these pre-programmed units. An hour after it arrived, his car was running like new. The relief on his face was incredible—he went from feeling defeated to feeling empowered, all because he found the right part that didn’t require complicated follow-ups.”

Frequently Asked Questions
Do I need to do any programming after I receive this part?
No. We program the module to the VIN you provide before shipping. It arrives ready for installation. In some cases, a simple security or crankshaft variation relearn procedure may be necessary, which can be done without special tools.
Where do I provide my VIN?
Please enter your 17-digit Vehicle Identification Number (VIN) in the notes section during checkout or send it to us in a message after your purchase. We cannot ship your part until we have this information.
What is the difference between a PCM, ECM, and ECU?
These terms are often used interchangeably. PCM (Powertrain Control Module) typically controls both the engine and transmission. ECM (Engine Control Module) or ECU (Engine Control Unit) usually refers to a computer that controls only the engine functions. For your vehicle, this module serves as the central powertrain computer.
Is this a reliable, long-term solution?
Absolutely. Each module is meticulously inspected and programmed with the latest stable software from GM to address common factory issues. This ensures a durable and dependable repair that restores your vehicle’s original performance and reliability.
What happens if I install it and still have problems?
While this module solves the vast majority of electronic powertrain issues, it’s important to ensure your vehicle’s underlying mechanical and electrical systems (like wiring and sensors) are in good condition. We stand by our products and are here to help with troubleshooting if you encounter any issues after installation.
