Expert Insight: The Ghost in the Transmission
We once worked with a customer whose 2005 Silverado 2500 had what he called a ‘ghost in the transmission.’ It would slam into gear randomly and sometimes refuse to shift out of first. He spent hundreds on fluid flushes and new sensors with no luck. The real issue was a failing processor inside his original PCM sending corrupt data to the transmission. Installing a properly Programmed GM 89017750 PCM solved the problem instantly. The ‘transmission problem’ was never in the transmission at all—it was in the computer. This is a very common scenario for these vehicles.

Frequently Asked Questions
Where do I find my vehicle’s VIN?
Your 17-digit VIN can be found on a sticker inside the driver’s side door jamb, on a metal plate on the driver’s side of the dashboard (visible through the windshield), or on your vehicle’s registration and insurance documents.
Will I need to do anything after installation?
In most cases, you will need to perform a security relearn procedure (often called a Passlock or CASE relearn). This is a simple process that can typically be done without special tools and involves a sequence of key turns. Instructions are widely available online for your specific model.
Is this a plug-and-play part?
Because we program it to your VIN, it is as close to plug-and-play as possible. After the physical installation and the security relearn procedure, your vehicle should start and run correctly without requiring a trip to a dealer.
How do I provide my VIN after purchase?
After you complete your purchase, you will receive an order confirmation email. You can simply reply to that email with your VIN, or follow the specific instructions provided in the email to ensure we receive it promptly.
