Restore Your Malibu’s Driveability and Performance
If your 2006-2010 Chevrolet Malibu is suffering from erratic shifting, getting stuck in gear, or has an illuminated Check Engine Light, a failing Transmission Control Module (TCM) is a likely culprit. As a technician with over two decades of experience, I’ve seen how a faulty TCM can make a reliable car feel unpredictable and unsafe. This T42 TCM, part number 24256960, is the definitive solution, arriving pre-programmed to your car’s specific Vehicle Identification Number (VIN). This means you can skip the expensive dealership visit for programming and get your Malibu back to shifting smoothly and efficiently.
The TCM is the brain of your automatic transmission, controlling everything from gear changes to torque converter lockup. When it fails, communication between the engine and transmission breaks down, leading to the frustrating symptoms you’re likely experiencing. Our module restores that critical link, ensuring your transmission receives the correct commands for optimal performance and longevity.
A Technician’s Notebook: The Elusive Malibu Shifting Gremlin
I remember a 2009 Malibu that came into the shop with a complaint that stumped a few other mechanics. The owner reported harsh 1-2 shifts and occasional ‘limp mode’ engagement, but only after driving for 30+ minutes in city traffic. We scanned it and found intermittent solenoid codes (like P0752). The wiring checked out, and the solenoids themselves tested fine when cool. The problem was heat soak. The original TCM’s internal circuits were failing as under-hood temperatures rose, causing erratic signals. We installed one of our VIN-programmed T42 modules, and the problem vanished instantly. It’s a classic failure mode for these units, and this part is the direct fix.
Is Your Malibu Showing These Telltale Signs?
A failing TCM doesn’t always mean total transmission failure. Often, the signs are subtle at first. Here’s what to look for:
- âś” Harsh, jerky, or delayed gear shifts.
- âś” The vehicle getting stuck in one gear (often called “limp mode”).
- âś” Check Engine Light or Transmission Warning Light is on.
- âś” Diagnostic Trouble Codes (DTCs) stored, especially P0700 (Transmission Control System Malfunction) or various solenoid-specific codes.
- âś” A sudden drop in fuel economy.
- âś” The transmission seems to slip between gears.
A Straightforward Guide to Your Malibu TCM Installation
One of the best features of this part is its simple installation, which most DIYers can complete in under an hour with basic hand tools. For the 2006-2010 Malibu, the TCM is located on the left-hand (driver’s side) frame rail. Follow these steps for a successful replacement:
- Safety First: Always disconnect the negative terminal from your car’s battery before starting any electrical work. This prevents short circuits and helps reset the vehicle’s electronic systems.
- Locate the Module: Find the TCM mounted to the driver’s side frame rail in the engine compartment. You may need to move the air cleaner box for better access.
- Disconnect and Remove: Carefully unplug the electrical connectors. They have locking tabs, so be gentle. Then, unbolt the module from its mounting bracket.
- Install the New TCM: Bolt the new, pre-programmed module into place. Reconnect the electrical connectors, ensuring they click securely into place.
- Final Steps: Reconnect the battery terminal. While our VIN programming handles the critical setup, it’s good practice to use a basic OBD2 scan tool to clear any lingering fault codes from the computer’s memory. Start the car and take it for a test drive to confirm the smooth shifting.

Frequently Asked Questions
What exactly does a VIN-programmed TCM do for my Malibu?
VIN programming loads your car’s specific software and calibrations onto the module before it ships. This ensures it communicates perfectly with your Malibu’s engine computer and other systems right out of the box, just like the original part did from the factory.
Do I need to take my car to a dealership after installation?
No. Because this module comes pre-programmed to your VIN, you do not need any additional, expensive programming from a dealer or specialized shop. It’s designed for plug-and-play installation.
How difficult is it to replace the TCM on a 2006-2010 Malibu?
It’s a straightforward job for a confident DIYer. The module is accessible on the driver’s side frame rail and only requires basic hand tools to unbolt and swap the connectors. The entire process typically takes less than 30 minutes.
Will this part 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 internal failure), P0700 can also be triggered by other issues. However, if you’re also experiencing shifting problems, a faulty TCM is the most common cause.
Is there a core charge for this part?
No, there is no core charge. You are not required to send your old, faulty module back to us, saving you time and return shipping costs.
