From the Mechanic’s Bench: I remember a customer with a 2004 Chevy Venture, the family’s only vehicle. It was stalling intermittently, making his wife afraid to drive it with the kids. The dealer quoted them over a thousand dollars for a new computer and the required programming. They were stressed and felt stuck. We provided them with a Programmed 89017735 PCM, just like this one. He installed it himself in under an hour in his driveway. The van started right up, the check engine light was gone, and the stalling issue vanished completely. He didn’t just fix his van; he restored his family’s safety and his own peace of mind, all for a fraction of the dealer’s price.
Frequently Asked Questions
Do I need to do any programming myself?
Absolutely not. We handle all the programming before the part is shipped. Once you receive the module, you simply install it, and your vehicle will be ready to go. This is a true plug-and-play solution.
How do I provide my Vehicle Identification Number (VIN)?
After you complete your purchase, we will send you a message requesting your vehicle’s 17-digit VIN. We cannot ship your part until we receive the VIN, as the programming is specific to your exact vehicle.
Will I need to perform a CASE Relearn procedure?
In some cases, a Crankshaft Variation Relearn (also known as CASE Relearn) may be needed to prevent a P1336 trouble code and ensure optimal engine timing. This is a simple procedure that can be performed with many mid-range professional scan tools but is not always required.
How can I be sure this fits my vehicle?
This module fits a wide range of GM vehicles. Please review the detailed fitment list on this page. The most important step is to confirm that your original module has one of these part numbers on its label: 89017735, 12583827, or 12583826. Matching the part number is the best way to guarantee compatibility.
What if I have an anti-theft system?
For vehicles equipped with a Passlock or other anti-theft system, a security relearn procedure may be required after installation. This is a simple process that typically involves turning the key on and off in a specific sequence and does not require any special tools. Instructions are widely available online for your specific model.
