Restore Flawless Shifting to Your Chevrolet Impala

If your 2006-2011 Chevrolet Impala is suffering from jarring shifts, getting stuck in gear, or has an illuminated check engine light, a failing Transmission Control Module (TCM) is the most likely culprit. As a technician with over two decades of experience, I’ve seen firsthand how a faulty TCM can make a reliable car feel unpredictable and unsafe. This isn’t just an annoyance; it’s a critical failure that compromises your car’s performance and fuel economy. This direct-fit T42 TCM, part number 24256960, is the definitive solution, arriving pre-programmed to your car’s specific VIN for a true plug-and-play repair.

From the Diagnostic Bay: The P0752 Solenoid Ghost

A customer brought in his ’08 Impala with a persistent P0752 code (Shift Solenoid ‘A’ Stuck On). He had already replaced the solenoid twice at another shop, but the code and the harsh 1-2 shift kept returning. We hooked up our scope and monitored the command signal from the TCM. The signal was erratic and inconsistent, even when the solenoid should have been off. The issue wasn’t the solenoid at all; it was a failing driver circuit inside the original TCM. We installed one of our VIN-programmed modules, cleared the codes, and the car shifted perfectly. It’s a classic case where chasing codes costs more than correctly diagnosing the root cause—the module itself.

Is Your Impala Showing These Telltale Signs?

A failing TCM doesn’t always mean total transmission failure. Often, it presents as a series of frustrating electronic and mechanical symptoms. If you’re experiencing any of the following, this module is your solution:

  • ✔ Harsh, banging, or erratic gear shifts.
  • ✔ The vehicle is stuck in “limp mode” (usually 2nd or 3rd gear).
  • ✔ Check Engine Light is on with transmission-related Diagnostic Trouble Codes (DTCs) like P0700, P0750, P0752, or other solenoid circuit faults.
  • ✔ Delayed engagement when shifting from Park to Drive or Reverse.
  • ✔ Failure to upshift or downshift properly, leading to poor acceleration.
  • ✔ A noticeable drop in fuel efficiency.

A Straightforward Guide to Installation

One of the best features of this module is its simple installation, which a DIY enthusiast can complete in their driveway in under 30 minutes. For the 2006-2011 Impala, the TCM is located right under the lower air cleaner housing, making it easily accessible.

  1. Safety First: Disconnect the negative terminal from your vehicle’s battery to prevent any electrical shorts and to help reset the system.
  2. Locate the Module: Remove the engine cover and the air cleaner assembly. You will see the TCM mounted below it.
  3. Disconnect and Remove: Carefully unplug the electrical connectors from the old TCM. Then, unbolt the module from its mounting bracket.
  4. Install the New Module: Bolt the new, pre-programmed TCM into place. Reconnect the electrical connectors, ensuring they click securely into place.
  5. Reassemble and Finalize: Reinstall the air cleaner housing and engine cover. Reconnect the battery terminal. Use a basic OBD2 scan tool to clear any stored fault codes. Start the vehicle and take it for a test drive to confirm smooth shifting.
