Expert Technician’s Insight
I once worked on a 2004 Corvette with a mysterious hesitation under acceleration that had stumped two other shops. They had replaced sensors and fuel system components to no avail. The issue was a failing processor inside the original PCM that only malfunctioned under specific loads. Swapping in a correctly programmed 2004 Corvette PCM 89017733 didn’t just fix the problemโit transformed the car. The owner called back a week later, ecstatic that his Corvette felt more responsive and powerful than it had in years. That’s the difference a healthy, correctly updated PCM makes.
Frequently Asked Questions
Do I need to do any programming after I receive it?
No. We program the module to the VIN you provide before shipping. It arrives ready to be installed. However, you will need to perform a security relearn procedure (often called a CASE or Crankshaft Variation Relearn) after installation, which can be done with a capable scan tool or by a qualified mechanic. This is a standard procedure required for any PCM replacement on these vehicles.
How do I provide my VIN?
After you complete your purchase, simply reply to your order confirmation email with your vehicle’s 17-digit VIN. We cannot ship your part until we receive this information, as the programming is specific to your car.
Is this a genuine GM part?
Yes, this is a genuine GM service component, ensuring the highest quality and perfect compatibility with your vehicle’s systems. We use only official GM software for all programming.
Will this fix my specific problem?
This 2004 Corvette PCM 89017733 is the solution for failures within the module itself. While it resolves the most common electronic engine and transmission issues, it’s crucial to ensure your vehicle has been properly diagnosed. This part will not fix problems related to faulty wiring, sensors, or mechanical components.
Where is the PCM located on my 2004 Corvette?
On the 2004 Corvette, the PCM is located in the engine compartment on the right-hand (passenger) side, near the firewall.
