Is Your Impala’s Transmission Acting Up?
Is your 2006-2011 Chevrolet Impala suffering from harsh, unpredictable shifting, getting stuck in gear, or flashing a check engine light? A failing Transmission Control Module (TCM) can turn your reliable daily driver into a source of constant stress.

Common Symptoms & Your Solution
A faulty TCM can manifest in several ways, making your car feel unreliable and unsafe. If you’re experiencing any of the following, it’s a strong indicator that your module needs replacement:
- Erratic or Harsh Shifting: Abrupt, jerky gear changes or a noticeable delay when the transmission shifts.
- 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.
- Diagnostic Trouble Codes (DTCs): Common codes like P0700, P0750, or other solenoid-related faults are stored in the computer.
- Poor Performance: A noticeable drop in fuel economy, sluggish acceleration, or a complete failure to shift.

Frequently Asked Questions
What does a TCM do on my 2006-2011 Impala?
The Transmission Control Module, or TCM, is the electronic brain of your automatic transmission. It collects data from various sensors in the engine and transmission to control exactly when and how the car shifts gears, ensuring optimal performance, fuel efficiency, and smoothness.
Is this module difficult to install?
For the Impala, the TCM is typically located in the engine bay under the air cleaner housing. Installation is straightforward for someone with basic mechanical skills and can often be completed in under an hour. We recommend disconnecting the battery before starting the replacement.
Do I need to take my car to a dealer after installation?
No. Because this unit is pre-programmed to your car’s VIN, no additional programming or dealer visits are required. It is a true plug-and-play solution. You may need a basic scan tool to clear any old fault codes after installation.
How do I know this is the right part for my car?
This 2006-2011 Impala T42 Transmission Control Module is guaranteed to be the correct fit for the specified model years. You can also verify by matching your old part number to the service numbers listed, such as 24241806, 24252114, or 24234503.
What happens if I don’t replace a failing TCM?
Ignoring a failing TCM can lead to more severe and expensive problems. Continued harsh shifting can cause premature wear on internal transmission components like clutches and bands, potentially leading to a complete transmission failure that requires a costly rebuild or replacement.
