Restore Smooth, Reliable Shifting to Your Chevrolet Malibu
If your 2006-2010 Chevrolet Malibu is suffering from harsh shifting, getting stuck in gear, or throwing transmission-related trouble codes, the problem is very likely a failing Transmission Control Module (TCM). As a technician with over two decades of experience, I’ve seen countless GM vehicles, including the Malibu, come into the bay with these exact issues. The T42 TCM is the electronic brain of your automatic transmission, and when it fails, it can make your car feel unpredictable and unsafe. This replacement module, part number 24235732, is the definitive solution to get your car driving like new again.
The biggest headache with replacing a TCM has always been the expensive and time-consuming trip to the dealership for programming. We eliminate that step entirely. We pre-program this module to your car’s specific Vehicle Identification Number (VIN) before it ships. This means it arrives at your door ready for a true plug-and-play installation, instantly communicating with your vehicle’s systems for optimal performance and clearing those persistent fault codes. This is the same process we use in our own shop to guarantee a fast, effective repair.
From the Diagnostic Bay: The ‘Ghost in the Machine’ Malibu
A customer brought in a 2009 Malibu complaining of intermittent ‘slamming’ into gear and occasional failure to shift out of 2nd. They’d already replaced a shift solenoid with no luck. On my scan tool, I saw a generic P0700 code but also a history of communication loss codes with the TCM. This is a classic sign. The module wasn’t just failing; it was intermittently dropping offline, causing the erratic behavior. We installed a VIN-programmed 2006-2010 Malibu TCM, and the problem was solved in under an hour. The issue wasn’t a mechanical fault in the transmission, but a faulty computer controlling it.
Is Your Malibu Showing These Telltale Signs?
- ✔ Harsh, jerky, or delayed gear shifts.
- ✔ Vehicle is stuck in “limp mode” (usually 2nd or 3rd gear).
- ✔ Check Engine Light or Transmission Warning Light is on.
- ✔ Diagnostic Trouble Codes (DTCs) are present, such as P0700, P0750, or other solenoid-specific codes.
- ✔ A complete loss of shifting ability or failure to engage a gear from park.
- ✔ Poor fuel economy and a feeling of sluggish performance.
A Straightforward DIY Installation Guide
You don’t need to be a master mechanic to replace the 2006-2010 Malibu TCM. With basic hand tools, you can complete this job in your own driveway in about 30 minutes. For the 2006-2010 Malibu, the TCM is typically located on the driver’s side frame rail, in the front of the engine compartment.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery before beginning any electronic work.
- Locate the Module: Find the TCM on the driver’s side (LH) frame rail. It’s a small silver box with electrical connectors.
- Disconnect and Remove: Carefully unplug the wiring harness connectors. Then, unbolt the old module from its mounting bracket.
- Install the New TCM: Bolt the new, pre-programmed module into place and securely reconnect the wiring harnesses. Ensure they click into place.
- Final Steps: Reconnect the battery terminal. While our programming handles the critical setup, it’s always best practice to use a basic OBD2 scanner to clear any stored fault codes from the ECU.

What does a Transmission Control Module do?
What does a Transmission Control Module do?
The TCM is a computer that controls your automatic transmission’s functions. It reads data from sensors to manage shift timing, line pressure, and torque converter lockup, ensuring smooth and efficient operation.
Why is VIN programming so important?
VIN programming loads your vehicle’s specific software and calibrations onto the module. Without it, the TCM won’t communicate correctly with your car’s other computers, leading to continued shifting problems or a no-start condition. Our service saves you a mandatory trip to the dealer.
Is this a difficult part to install myself?
Not at all. For the Malibu, it’s located in an accessible spot on the driver’s side frame rail. With basic tools, it’s a simple unbolt-and-unplug process that most DIYers can handle in under an hour.
Will this fix a P0700 trouble code?
A P0700 code is a general fault code indicating the TCM has detected a problem. In many cases, a failing TCM is the root cause. Replacing the module with our pre-programmed unit will often resolve the P0700 and any related transmission codes.
Is there a core charge?
No, there is no core charge for this part. You can keep or dispose of your old module without any extra hassle or fees.
