Is Your Trusty GM Truck or SUV Suddenly Unreliable?
It’s frustrating when the vehicle you depend on every day starts acting up. If your late-90s Suburban, Tahoe, or GMC/Chevy pickup is suffering from a persistent Check Engine Light, erratic shifting, stalling, or even a no-start condition, the problem often points directly to a failing Powertrain Control Module (PCM). This isn’t just an inconvenience; it’s a critical issue that compromises your vehicle’s performance, fuel economy, and reliability. Driving with a faulty PCM can lead to further damage and leave you stranded. You need a solution that’s not only effective but also gets you back on the road without hassle.

- Engine stalling, stumbling, or rough idling.

Frequently Asked Questions
What is a PCM and what does it do?
The Powertrain Control Module (PCM), also known as the Engine Control Module (ECM), is the main computer in your vehicle. It controls all aspects of engine and transmission operation, including fuel injection, ignition timing, and transmission shift points, to ensure optimal performance, fuel economy, and emissions.
How do I provide my VIN for programming?
After you complete your purchase, you will need to send us your 17-digit Vehicle Identification Number (VIN). You can typically add it as a note during checkout or send it to us in a message referencing your order number. We cannot ship your part until we receive your VIN, as the programming is specific to your vehicle.
Is any additional programming needed after I install it?
No. This module is a complete plug-and-drive solution. Because we program it to your VIN before shipping, you will not need to take it to a dealer or mechanic for additional programming. However, on some models, a simple security relearn procedure may be necessary, which can be done without any special tools. We can provide instructions for this if needed.

Please check the extensive fitment list provided on this page. This module is a direct replacement for the part numbers listed.
