Expert Insight: The Ghost in the Machine
“We had a customer with a 2003 Silverado 2500 with the 8.1L engine who was about to replace his transmission. It was shifting hard and intermittently throwing codes that pointed to internal transmission failure. He’d already replaced multiple sensors. On a hunch, we suggested he check the PCM. After installing our pre-programmed unit, every single shifting problem vanished instantly. The ‘bad transmission’ was actually a faulty computer all along. It saved him thousands in unnecessary repairs and got his work truck back on the job.”
Don’t let a faulty computer keep your vehicle sidelined. This programmed GM PCM 12581565 is the most reliable and efficient way to solve complex electronic issues and restore your vehicle to its peak operational state. Simply provide your VIN at checkout, and we’ll handle the rest.
Frequently Asked Questions
Where do I provide my Vehicle Identification Number (VIN)?
After you complete your purchase, you will need to send us your 17-digit VIN. We cannot ship your part until we receive this information, as the programming is essential for the module to function in your vehicle.

In many cases, you may need to perform a security relearn procedure, which can often be done without special tools. Some vehicles may also require a Crankshaft Variation Relearn (CASE Relearn) to be performed with a capable scan tool for optimal performance and to clear certain codes.
Is this a new or used part?
This is a quality, inspected, and tested used OEM component. Each unit is verified to be fully functional before being programmed with the latest GM software for your specific vehicle.
