Are you tired of your 2005 Grand Prix’s unpredictable shifting, check engine light, and the nagging worry of a failing transmission?

Expert Insight: The Critical Role of VIN Programming
From the Technician’s Bench: Many people don’t realize that a TCM isn’t a generic part you can just swap out. On these GM vehicles, the module is the ‘brain’ of the transmission, and it needs to be perfectly matched to your car’s specific options and serial number (VIN). Using a module from another car or one that hasn’t been programmed is a recipe for failure. We handle this complex process for you, using your VIN to load the exact factory file your Grand Prix needs. This ensures all solenoids and sensors operate exactly as the engineers intended, which is the key to a successful and lasting repair with a Programmed 2005 Pontiac Grand Prix TCM.
Don’t let a faulty module sideline your car. This is the most effective way to address the core electrical issues plaguing your transmission. By providing us with your VIN at checkout, you ensure that the Programmed 2005 Pontiac Grand Prix TCM you receive is a true plug-and-play component, getting you back on the road quickly and confidently.
Frequently Asked Questions
Do I need to take this part to a dealer for programming?
No. The main benefit of our service is that we program the module to your vehicle’s specific VIN before we ship it. This means it arrives ready for installation without the need for expensive dealer tools or additional programming fees.
Where is the TCM located on a 2005 Pontiac Grand Prix?
On the 2005 Grand Prix, the Transmission Control Module is typically located in the engine bay, mounted to the lower air cleaner housing. Always disconnect the battery before attempting installation.
Is this a difficult part to install?
For someone with basic mechanical skills and tools, this is a very manageable DIY job. It involves removing the air cleaner assembly for access, disconnecting the electrical connectors, and unbolting the old module. Since ours is pre-programmed, no complex computer work is needed on your end.
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 and validate your VIN, as this is essential for the programming process.
Will this fix my check engine light?
If your check engine light is on due to a fault code directly related to the TCM or its functions (like shift solenoid errors or communication faults), then yes, this part is designed to correct that root cause. After installation, you may need to clear the codes with a standard OBD2 scanner.
My original part number isn’t YDLT. Will this still work?
Yes, this module is compatible with a range of part numbers. It is a direct replacement for the following: 24223112, 24226863, 24233595, 24234189, 24239427, YBWW, YDFC, YDFD, YDLT, YJHY, YKTB, and YKTF. We program it to function perfectly for your specific vehicle.
