Restore Flawless Shifting to Your GM Vehicle
Is your 2005 Buick Allure or other GM vehicle suffering from erratic shifting, delayed gear engagement, or getting stuck in ‘limp mode’? These are classic symptoms of a failing Transmission Control Module (TCM). As a technician with over two decades of experience, I’ve seen how a faulty TCM can make a perfectly good car feel unreliable and unsafe. This isn’t just an inconvenience; it’s a critical failure that disrupts the communication between your engine and transmission, leading to poor performance and fuel economy.
This replacement 2005 Allure Transmission Control Module is the definitive solution. We take the guesswork and extra cost out of the repair by pre-programming the unit specifically for your vehicle. Simply provide us with your Vehicle Identification Number (VIN) after purchase, and our experts will flash the module with the latest, most stable software updates directly from GM. This means no expensive trips to the dealership for programming—it arrives at your door ready for a straightforward installation.
A Technician’s Notebook: The Intermittent Shifting Nightmare
A customer brought in a 2005 Pontiac Grand Prix with a complaint that stumped two other shops: intermittent, bone-jarring shifts from 1st to 2nd gear, but only after the car was fully warmed up. There were no consistent trouble codes, just a generic P0700 (Transmission Control System Malfunction) that would pop up occasionally. After checking fluid levels and solenoids, my gut told me it was the TCM. Heat soak was likely causing an internal circuit board failure. We swapped in a VIN-programmed TCM, and the problem vanished instantly. The pre-flashed module saved the customer a full day of dealership diagnostics and programming fees, turning a frustrating issue into a simple, one-hour fix.

A Straightforward Guide to Installation
Installing your new 2005 Allure Transmission Control Module is a job most DIYers can handle with basic tools. This plug-and-play solution eliminates the most difficult step—programming.
- Safety First: Disconnect the negative terminal from your vehicle’s battery to prevent any electrical shorts.
- Locate the Old TCM: On many of these models, the TCM is located under the air cleaner housing or on the LH side of the engine compartment. Consult a vehicle-specific repair guide if you’re unsure.
- Disconnect and Remove: Carefully unplug the electrical connectors from the old module. Press the release tabs firmly. Then, unbolt the module from its mounting bracket.
- Install the New Module: Bolt the new, pre-programmed TCM into place. Securely plug in the electrical connectors until they click, ensuring a solid connection.
- Reconnect and Test: Reconnect the negative battery terminal. Start the vehicle and allow it to idle for a minute. Take the vehicle for a test drive to confirm that shifting is smooth and the check engine light is off.

Frequently Asked Questions
Do I need to get this module programmed by a dealer?
No. We program the module to your car’s specific VIN before we ship it. It arrives ready to install, saving you time and money.
What information do you need from me?
After you place your order, you will need to provide us with your 17-digit Vehicle Identification Number (VIN). This is typically found on your driver’s side dashboard (visible through the windshield) or on the driver’s door jamb sticker.
Will this fix a P0700 trouble code?
A P0700 code is a general fault code indicating the TCM has detected a problem. While a faulty TCM is a very common cause, you should ensure other potential issues (like low fluid or bad solenoids) have been ruled out. In many cases, replacing the TCM will resolve the P0700 and related codes.
Is this a new or used part?
This is a high-quality, inspected replacement part that has been tested and prepared with new GM software to ensure reliability and performance.
How long does the programming process take?
Once we receive your VIN, programming is typically completed within one business day, after which your order will be shipped.
