Common Symptoms & Your Solution
A failing TCM can manifest in several ways, often getting progressively worse. If you’re noticing any of the following, it’s a strong indicator that your module needs replacement:
- Harsh, erratic, or delayed gear shifting
- The vehicle entering “limp mode,” often stuck in 2nd or 3rd gear
- Illuminated Check Engine or Transmission warning lights
- Diagnostic Trouble Codes (DTCs) such as P0700, P0750, or other solenoid-related faults
- Failure to upshift or downshift, leading to poor acceleration and fuel economy
This pre-programmed 2006-2011 Impala Transmission Control Module is the direct answer to these problems, arriving ready for a plug-and-play installation without requiring an expensive trip to the dealership for programming.

An Expert’s Insight: Skip the Dealership Headaches
Many drivers don’t realize that a standard replacement TCM is just a metal box until it’s programmed. This usually means installing the part and then having your vehicle towed to a dealership, where you’ll pay a premium for them to flash it with the correct software. Our VIN programming service completely eliminates that costly and time-consuming step. We handle the complex software side for you, so when the part arrives, your mechanic—or you, if you’re a skilled DIYer—can simply install it, clear any old codes, and be back on the road. It’s the smartest way to fix your transmission electronics.
By choosing this expertly prepared 2006-2011 Impala Transmission Control Module, you’re not just buying a part; you’re investing in a reliable, long-term solution that brings peace of mind. End the transmission troubles and restore your vehicle’s dependability today.
Frequently Asked Questions
Do I need to get this TCM programmed by a dealer?
No. This is the primary benefit of our service. We pre-program the module to your vehicle’s VIN before it ships, so it is ready to install right out of the box. No additional flashing or programming is required.
Where is the TCM located on a 2006-2011 Impala?
On the 2006-2011 Chevrolet Impala, the transmission control module is typically located inside or attached to the lower air cleaner housing in the engine bay. Always disconnect the battery before beginning the replacement.
Will this fix a P0700 trouble code?
A P0700 code is a general fault code indicating the TCM has detected a problem. While this module often resolves the root cause (like a faulty solenoid circuit within the TCM), you should always diagnose any other related codes to ensure there aren’t external wiring or sensor issues. Replacing a faulty 2006-2011 Impala Transmission Control Module is a very common fix for this code.
Is this a difficult part to install?
For someone with moderate mechanical experience, the installation is straightforward and can typically be completed in under an hour. It involves locating the module, disconnecting the battery, unplugging the electrical connectors, and unbolting the unit. Since it’s pre-programmed, there are no complicated software steps involved.
What happens if I don’t replace a failing TCM?
Ignoring the symptoms of a failing TCM can lead to more severe issues. Continued harsh shifting can cause premature wear on internal transmission components, potentially leading to a much more expensive mechanical failure down the road. It can also leave you stranded if the vehicle gets stuck in limp mode.
Is there a core charge for this part?
No, there is no core charge. You are not required to return your old, non-working part, which simplifies the process for you.
