Is Your 2006-2011 Chevrolet Impala Shifting Erratically?
If you’re experiencing harsh shifts, delayed gear engagement, or your Impala is stuck in ‘limp mode,’ a failing Transmission Control Module (TCM) is the most likely culprit. The TCM is the electronic brain of your automatic transmission, responsible for orchestrating every gear change with precision. When it begins to fail, it can cause a cascade of frustrating and potentially damaging issues, from poor fuel economy to a complete inability to shift gears. Don’t let a faulty module sideline your vehicle. This OEM-quality T42 TCM, part number 24235753, is the definitive solution to restore your transmission’s performance and your driving confidence.
From the Diagnostic Bay
We recently had a 2009 Impala towed in with the check engine light on and the transmission locked in 3rd gear. The owner was worried about a costly transmission rebuild. After connecting our scan tool, we pulled a P0700 code (Transmission Control System Malfunction) along with several solenoid circuit codes. Instead of jumping to conclusions, we checked the TCM connections and power. Everything was fine. Experience pointed directly to an internal failure in the original TCM. We installed one of our VIN-programmed T42 modules, cleared the codes, and the car was shifting perfectly on the test drive. It’s a common story, and this module saved the customer thousands compared to a full transmission replacement.
Key Symptoms of a Failing 2006-2011 Impala TCM
A failing TCM doesn’t always mean a complete transmission shutdown. Often, the symptoms start intermittently and worsen over time. Recognizing these early warning signs can save you from further component damage. This module is engineered to resolve these exact issues.
- ✔️ Harsh or Erratic Shifting: Gears may slam into place, or the transmission might hesitate and hunt for the right gear.
- ✔️ Stuck in Gear / Limp Mode: The vehicle may refuse to shift out of a single gear (often 2nd or 3rd) as a protective measure.
- ✔️ Warning Lights: The Check Engine Light or a dedicated transmission warning light will illuminate on your dashboard.
- ✔️ Diagnostic Trouble Codes (DTCs): Common codes include P0700, P0750, and other solenoid-specific faults that point to an electronic control issue.
- ✔️ Delayed Engagement: A noticeable lag when shifting from Park into Drive or Reverse.
- ✔️ Poor Fuel Economy: Inefficient shifting and torque converter lock-up issues caused by the faulty TCM can lead to a significant drop in MPG.
- ✔️ No Communication: In severe cases, a scan tool may be unable to communicate with the TCM, indicating a total failure.

Frequently Asked Questions
Do I need to take my car to the dealer after installing this TCM?
No. This Transmission Control Module is pre-programmed to your vehicle’s VIN before it ships. This makes it a true plug-and-play solution, requiring no additional programming or trips to the dealership.
Where is the TCM located on my 2006-2011 Impala?
On the 2006-2011 Chevrolet Impala, the TCM is typically found in the engine bay, mounted to the lower air cleaner housing. This location makes it easily accessible for replacement.
Will this fix my 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 (such as internal TCM failure), it’s essential to diagnose any other specific codes that accompany the P0700. In most cases where the TCM itself is faulty, this part is the correct fix.
Is this part compatible with other GM vehicles?
Yes, this T42 TCM is compatible with a wide array of GM vehicles from 2006-2014 that use 4-speed automatic transmissions like the 4L60E and 4L65E. This includes models like the Silverado, Tahoe, Yukon, LaCrosse, Grand Prix, and more. Please verify the fitment list for your specific vehicle.
