Is your Buick Allure suffering from transmission problems?
If you’re experiencing frustrating and unpredictable shifting, a check engine light that won’t go away, or the unnerving feeling of your car being stuck in ‘limp mode,’ a failing Transmission Control Module (TCM) is the most likely culprit. These symptoms can turn a comfortable daily drive into a stressful ordeal. This pre-programmed T42 TCM is the definitive solution, designed to restore the smooth, reliable performance your Buick was built for, without a costly trip to the dealership.
Common Symptoms & Your Solution
A faulty TCM can manifest in various ways, often leading to misdiagnosis. If your vehicle is showing any of these signs, this module is your answer:
- Harsh, jerky, or delayed gear shifts
- The vehicle gets stuck in a single gear (limp mode)
- Transmission or Check Engine warning lights are illuminated
- Diagnostic Trouble Codes (DTCs) such as P0700, P0750, or other solenoid-related codes
- Failure to upshift or downshift correctly
- Noticeably poor fuel economy
Replacing your old unit with our pre-programmed 2006-2009 Buick Allure Transmission Control Module directly resolves these issues, restoring communication between your engine and transmission for precise, factory-spec operation.

An Expert’s Note on Programming
Many people don’t realize that a new TCM won’t work correctly if it’s not programmed to the car’s unique VIN. Installing a non-programmed module from a junkyard or a generic online seller will often result in the car not starting or shifting at all. Our VIN programming service handles this critical step for you. We load the latest GM software onto the module before it ships, so you can install it with basic tools and be back on the road in under an hour. It’s the smartest way to fix your car right the first time.

You’re ensuring your vehicle is safe, reliable, and performs as it should. This is the ideal fix for the specific transmission issues found in the Buick Allure and a wide range of other GM vehicles. Don’t let a faulty module dictate your driving experience—install the trusted solution and regain control.
Frequently Asked Questions
Will I need to take my car to a dealership after installing this?
Absolutely not. The primary benefit of our service is that the 2006-2009 Buick Allure Transmission Control Module comes fully programmed to your vehicle’s VIN. This eliminates the need for any additional, expensive programming at a dealership or repair shop. It’s ready to install right out of the box.
Is this part difficult to install myself?
For most models, including the Buick Allure, the TCM is located in the engine compartment (often near the air cleaner housing) and is accessible with basic hand tools. The installation typically takes less than 30 minutes. We recommend disconnecting the battery before you begin to allow the vehicle’s systems to reset.
How do I provide my VIN for programming?
The VIN can be easily added during the checkout process on our website. You can find your 17-digit VIN on your vehicle’s registration, insurance card, or on the driver’s side dashboard viewable through the windshield.
What is a ‘core charge’ and why don’t you have one?
A core charge is a deposit that other sellers charge you until you return your old, faulty part. We’ve simplified the process by not requiring a core charge. This saves you the time, money, and hassle of shipping your old part back to us.
Does this module fit other GM vehicles?
Yes, this T42 TCM is compatible with a very wide range of 2006-2014 GM vehicles equipped with 4-speed automatic transmissions like the 4L60E and 4L65E. This includes many Chevrolet, GMC, Pontiac, Saturn, and Cadillac models. Please verify the part number or use our vehicle lookup tool to confirm an exact match.
