If your 2006-2010 Chevrolet Malibu is suffering from poor shifting, getting stuck in gear, or has an illuminated check engine light, a failing Transmission Control Module (TCM) is a very likely culprit. As a technician with over two decades of experience, I’ve seen countless drivers worry about a complete transmission rebuild when the real issue was this electronic brain. This OEM-quality T42 TCM, part number 24252114, is the definitive solution to restore your vehicle’s performance and peace of mind.
The TCM is the nerve center of your automatic transmission. It processes data from vehicle sensors to control shift solenoids, manage torque converter clutch lockup, and regulate fluid pressure. When it fails, communication breaks down, leading to the frustrating and sometimes dangerous symptoms you’re experiencing. Our replacement module is expertly programmed to your vehicle’s specific VIN, ensuring it works perfectly right out of the box, with no expensive trip to the dealership required for coding.
Is Your Malibu Showing These Transmission Warning Signs?
A faulty 2006-2010 Malibu TCM can mimic the symptoms of a much more serious mechanical failure. Before you condemn the transmission, check for these common indicators of a bad module:
- ✔ Jerky, unpredictable gear changes or a noticeable ‘bang’ when shifting.
- ✔ The vehicle is stuck in a single gear, often called ‘limp mode,’ to prevent further damage.
- ✔ Check Engine Light or Transmission Warning Light is on, with Diagnostic Trouble Codes (DTCs) like P0700, P0750, or other solenoid-specific codes.
- ✔ Failure to upshift or downshift, resulting in poor acceleration and terrible fuel economy.
- ✔ Delayed engagement when shifting from Park to Drive or Reverse.
- ✔ Inconsistent performance that seems to worsen as the vehicle warms up.
Case Study: A Tricky Diagnosis
A customer brought in a 2009 Malibu, convinced the transmission was shot. It was slamming into gear and wouldn’t shift past 2nd. The quote from another shop was for a full transmission replacement. I hooked up my pro-level scan tool and saw a classic P0700 (Transmission Control System Malfunction) and a U0101 (Lost Communication with TCM). Instead of a multi-thousand dollar repair, the fix was this exact part. After a 20-minute swap and clearing the codes, the car shifted like it just left the factory. This module saved the customer a huge amount of money and stress.
A Straightforward Guide to Your Malibu TCM Swap
Replacing the 2006-2010 Malibu TCM is a job most DIYers can handle in their own driveway. For the Malibu, you’ll find it located on the driver’s side frame rail. Follow these steps for a successful installation:
- Safety First: Always disconnect the negative terminal from your vehicle’s battery to prevent electrical shorts and help reset the vehicle’s electronic systems.
- Locate the Module: On the 2006-2010 Malibu, the TCM is typically mounted to the left-hand (driver’s side) frame rail in the engine compartment.
- Disconnect and Remove: Carefully unclip the electrical connectors. Press the release tabs firmly. Then, unbolt the module from its mounting bracket.
- Install the New Module: Bolt the new, pre-programmed TCM into place. Reconnect the electrical harnesses, ensuring they click securely into position.
- Final Steps: Reconnect the battery terminal. Start the vehicle and allow it to idle for a few minutes. If you have a basic scan tool, it’s good practice to clear any stored DTCs from the system.

Is this part really plug-and-play?
Is this part really plug-and-play?
Yes. We program the module to the VIN you provide during checkout. This ensures it has the correct software for your Malibu’s specific configuration, allowing for immediate installation without any need for a dealership visit or special programming tools.
Do I need to return my old TCM?
No, there is no core charge for this part. You can keep your old module, which saves you the hassle and cost of return shipping.
What happens if I don’t disconnect the battery?
While the replacement might still work, skipping this step is not recommended. Disconnecting the battery helps protect the new module and your vehicle’s electrical system from potential damage during installation and forces a ‘hard reset’ of the onboard computers, which helps them recognize the new part.
Will this fix a P0700 code?
A P0700 code is a general fault code indicating the TCM has detected a problem. In many cases, replacing a faulty TCM will resolve the P0700 and any related codes (like solenoid faults). However, you should always ensure the wiring and transmission components are in good condition as well.
What is the warranty on this module?
This Transmission Control Module comes with a one-year warranty, giving you confidence in the quality and reliability of your repair.
