Restore Your Impala’s Smooth, Reliable Shifting
Is your 2006-2011 Chevrolet Impala suffering from harsh shifting, getting stuck in gear, or displaying a persistent check engine light? These are classic signs of a failing Transmission Control Module (TCM). A faulty TCM can make your daily drive stressful and unpredictable, and ignoring it can lead to more significant transmission damage down the road. This professionally programmed GM T42 TCM is the definitive solution, designed to restore your vehicle’s performance and your peace of mind.
Common Symptoms & Your Solution
If your Impala is experiencing any of the following, a failing TCM is the likely culprit. This module is engineered to resolve these exact issues:
- Harsh or Erratic Shifting: Abrupt, jerky gear changes that make driving uncomfortable.
- Delayed Engagement: A noticeable pause when shifting from park into drive or reverse.
- Limp Mode: The vehicle gets stuck in a single gear (usually 2nd or 3rd) to prevent further damage.
- Warning Lights: The Check Engine Light or a specific transmission warning light is illuminated on your dash, often with Diagnostic Trouble Codes (DTCs) like P0700, P0750, or other solenoid-related codes.
- Poor Performance: A sudden drop in fuel economy, failure to upshift or downshift correctly, and a general feeling of sluggishness.
Installing our pre-programmed 2006-2011 Impala transmission control module is the most effective way to correct these problems, providing a reliable, long-term fix without the excessive cost and hassle of a dealership visit.

Expert Insight: Why VIN Programming is Non-Negotiable
In modern GM vehicles like your Impala, the TCM isn’t just a simple computer; it’s part of a complex network. It constantly communicates with the Engine Control Module (ECM) and Body Control Module (BCM). Without programming specific to your car’s VIN, the modules cannot ‘talk’ to each other correctly. This can lead to persistent error codes, poor performance, or even the vehicle not starting at all. Our VIN programming service uses the latest GM software updates, ensuring this 2006-2011 Impala transmission control module integrates seamlessly, just like the original part from the factory.
Frequently Asked Questions
Do I need to take this module to a dealer for programming?
Absolutely not. We handle all the programming before it ships. Simply provide your vehicle’s VIN during checkout, and the module will arrive ready for a direct, plug-and-play installation.
Where is the TCM located on a 2006-2011 Impala?
On this generation of Impala, the Transmission Control Module is typically found inside or mounted to the lower air cleaner housing in the engine bay, making it relatively accessible for replacement.
Is this a difficult part to install myself?
For someone with basic mechanical skills, this is a very manageable job that usually takes less than an hour. The key steps are disconnecting the battery, locating the old module, swapping the electrical connectors, and mounting the new one. No specialized tools are required.
Will this fix a P0700 trouble code?
A P0700 code is a general transmission fault code, meaning the TCM has detected a problem. In many cases, a failing TCM is the root cause of this code and the related specific codes it triggers. Replacing the module is a very common and effective solution for this issue.
What happens if I keep driving with a bad TCM?
Continuing to drive with a faulty TCM can cause long-term damage. Inconsistent hydraulic pressure and improper shifting can lead to premature wear on clutches and other internal transmission components, potentially turning a straightforward electronics replacement into a major mechanical overhaul.
