Expert Insight: The Critical Role of VIN Programming
Many people are tempted to grab a used computer from a salvage yard, hoping for a cheap fix. What they often discover is that a PCM is not a one-size-fits-all part.

Our process eliminates that risk entirely. We ensure the 2004 Corvette PCM 12581565 you receive is not just a compatible part, but the correct part for your unique vehicle.
Frequently Asked Questions
Is programming really included in the price?
Yes, it is. We flash the module with the latest dealer-level software from GM using the VIN you provide during checkout. There are no hidden fees for this essential service.
How do I provide my 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 have this information to program the module correctly.
Will I need to do anything after I install it?

This module is a direct replacement for several service numbers, including 12570557, 12576106, and 89017733, among others listed in the description. As long as your original number is on our compatibility list, this part will function correctly once programmed to your VIN.
