End Frustrating Shifting Problems for Good
Are you battling harsh shifts, a flashing check engine light, or a transmission that seems to have a mind of its own? A faulty Transmission Control Module (TCM) is one of the most common causes of these debilitating issues in your 2005 GM vehicle. Stop guessing and get the definitive solution. This module is professionally programmed with the latest GM software updates specifically for your vehicle’s VIN, ensuring a seamless installation and restoring the smooth, reliable performance you depend on.

Expert Insight: Why VIN Programming is Non-Negotiable
A common mistake is installing a used TCM from a salvage yard. While it might fit physically, it won’t work correctly without being programmed to your car’s specific VIN, engine, and options. This mismatch causes communication errors with the Engine Control Module (ECM) and Body Control Module (BCM), leading to more error codes and potentially damaging your transmission. Our VIN-matching service eliminates this risk entirely, ensuring the module communicates perfectly with your car’s network from the moment you install it. It’s the single most important step for a successful, long-lasting repair.

Frequently Asked Questions
Do I need to get this module programmed?
No. The main benefit of our service is that we program the module for you before it ships. It will arrive ready to be installed in your vehicle.
How do I provide my VIN number?
After you complete your purchase, you can send us a message with your 17-digit Vehicle Identification Number (VIN). We cannot ship your part until we receive it.
Is any other procedure needed after installation?
Yes. After installing the new TCM, you will need to perform a standard transmission adaptive pressure relearn procedure. This is a common step that can be done with many professional-grade scan tools and allows the module to learn the specific characteristics of your transmission for optimal shifting.
How can I be sure my TCM is the problem?
The symptoms listed above are strong indicators of a failing TCM. However, we always recommend having your vehicle professionally diagnosed to confirm the source of the issue. A proper diagnosis can rule out wiring problems or faulty solenoids, saving you time and money.
Will this fit models other than the 2005 Grand Prix?
Yes. Please check the detailed fitment list in the description. This module is compatible with many 2005 and some 2004 GM models, including the Corvette, Envoy, Cobalt, and more. Ensure your vehicle and specific options are listed.
