Is your 2006-2010 Chevrolet Malibu struggling with shifting problems? If you’re dealing with jerky gear changes, a car that won’t shift out of a low gear, or an illuminated Check Engine Light, a failing Transmission Control Module (TCM) is the most likely cause. As a technician with over two decades of experience, I’ve seen countless drivers worry they need a full transmission rebuild when the real issue is this electronic module. This T42 TCM, part number 24256960, is the definitive solution, pre-programmed to your vehicle’s VIN for a true plug-and-play repair.
A Technician’s Notebook
A customer brought in a 2008 Malibu, complaining it was “stuck in gear” and the ride was incredibly harsh. The dashboard was lit up with a Check Engine light. A quick scan pulled a P0700 (Transmission Control System Malfunction) and a few solenoid-specific codes. Instead of immediately quoting a costly internal transmission repair, we checked the TCM. Sure enough, it was failing. We installed one of our VIN-programmed T42 modules, cleared the codes, and took it for a test drive. The shifting was immediately smooth and responsive. The customer saved thousands and was back on the road in under an hour—a classic case where the electronic ‘brain’ was the problem, not the mechanical ‘body’ of the transmission.
Is Your Malibu Showing These Telltale Signs?
A faulty TCM can mimic more serious mechanical failures. Before you assume the worst, check if your vehicle is experiencing any of these common symptoms:
- ✔ Harsh, erratic, or delayed gear shifts that make driving uncomfortable.
- ✔ Vehicle is stuck in “limp mode,” often refusing to shift past 2nd or 3rd gear.
- ✔ Active Check Engine or Transmission warning lights on your dashboard.
- ✔ Diagnostic Trouble Codes (DTCs) present, such as P0700, P0750, or other solenoid-related faults.
- ✔ A noticeable drop in fuel economy or signs of the transmission overheating.
- ✔ Complete loss of communication with the transmission, preventing shifting.
DIY-Friendly Installation in Under 30 Minutes
Replacing the 2006-2010 Malibu Transmission Control Module is a straightforward job you can do at home. Because we pre-program the module to your VIN, you can skip the expensive trip to the dealership. Just follow these simple steps:
- Safety First: Always disconnect the negative terminal from your vehicle’s battery before starting any electronic repair.
- Locate the Module: On the 2006-2010 Malibu, the TCM is typically found mounted on the left-hand (driver’s side) frame rail in the front of the engine compartment.
- Swap the Part: Carefully unplug the wiring harnesses from the old module. Unbolt it from its mounting bracket and set it aside. Bolt the new module in its place and securely reconnect the harnesses.
- Final Steps: Reconnect the battery terminal. Use a standard OBD2 scan tool to clear any stored transmission codes. Start the vehicle and take it for a test drive to confirm smooth operation.

Frequently Asked Questions
Do I need to program this module?
No. This is the biggest benefit of our service. We pre-program the module to your car’s specific Vehicle Identification Number (VIN) before shipping. It arrives ready for installation, with no need for expensive scan tools or a trip to the dealership.
Where is the TCM on a 2006-2010 Chevy Malibu?
The TCM is located in the engine bay, attached to the driver’s side (LH) frame rail, near the front of the vehicle. It’s an external module, not inside the transmission pan, which makes for a much easier replacement.
Will this fix a P0700 trouble code?
Often, yes. P0700 is a general code indicating a fault within the transmission control system. It’s usually accompanied by more specific codes that point to a solenoid or the TCM itself. Replacing a faulty TCM is a very common fix for a P0700 code.
Is this a reliable, quality part?
Absolutely. This module is built to meet or exceed OEM specifications and is rigorously tested to ensure performance and durability. It’s backed by our one-year warranty for your peace of mind.
Is there a core charge?
No, we do not require a core charge. You can keep your old part, so there’s no hassle of shipping it back to us.
