Is your 2005 Pontiac Grand Prix suffering from erratic shifting, getting stuck in gear, or throwing a persistent check engine light? A failing Transmission Control Module (TCM) can turn a great drive into a frustrating and unpredictable experience. This isn’t just an inconvenience; it’s a core performance issue that compromises your car’s reliability. We offer the definitive solution: a professionally programmed TCM, flashed specifically to your vehicle’s VIN, that restores the crisp, responsive shifting you expect.
Common Symptoms & Your Solution
A faulty TCM can manifest in several ways, often triggering Diagnostic Trouble Codes (DTCs) like P0700, P0751, P0756, or U0101.

It’s the reliable, intelligent fix that directly addresses the electronic brain of your transmission, getting you back on the road with confidence.

Expert Insight: The ‘Programmed’ Difference
Many people are tempted to grab a used TCM from a junkyard to save money. However, a TCM is not a simple mechanical part; it’s a computer coded to a specific car. A module from another vehicle will have the wrong software and calibration, leading to immediate shifting problems or complete failure to operate. Our process of programming the module to your car’s VIN before shipping is what makes this a true, effective repair. You receive a programmed 2005 Grand Prix TCM that communicates flawlessly with your engine and other vehicle systems right out of the box.
Frequently Asked Questions
How do I provide my VIN number?
After you complete your purchase, you will receive instructions on how to send us your vehicle’s 17-digit VIN. We cannot ship your part until we receive this information, as the programming is essential for the part to function correctly.
Is this a difficult part to install?
For the 2005 Grand Prix, the TCM is typically located under the lower air cleaner housing, making it accessible for those with basic mechanical skills. Since our module comes pre-programmed, the installation is a direct swap. However, we always recommend consulting a service manual for your specific vehicle or having a qualified mechanic perform the installation if you are unsure.
Will this fix my specific transmission problem?
This programmed 2005 Grand Prix TCM is the correct solution for issues caused by a failed module, such as specific electronic fault codes and erratic shifting behavior. While it solves the most common problems, it’s important to ensure a proper diagnosis has been performed, as mechanical issues within the transmission can sometimes present similar symptoms.
Do I need to send my old part back?
No core charge or return is required for this part. You can keep or responsibly dispose of your old module.
What if I have a different 2005 GM vehicle?
This TCM is compatible with a wide range of 2005 GM models listed in the fitment chart, including the Corvette, GTO, Trailblazer, and more. As long as your vehicle is on the list and requires one of the compatible part numbers, this unit will be programmed for your specific model using your VIN.
