If your 2006-2010 Chevrolet Malibu is suffering from harsh, delayed, or unpredictable shifting, the problem often points directly to a failing Transmission Control Module (TCM). As an experienced technician, I’ve seen countless drivers chase expensive mechanical repairs when the real culprit was electronic. This T42 TCM, part number 24235753, is the definitive solution, arriving expertly programmed to your vehicle’s specific VIN for a true plug-and-play fix.
The TCM is the brain of your automatic transmission, controlling everything from gear changes to torque converter lockup. When it fails, you’ll experience frustrating and potentially unsafe driving conditions. Our service eliminates the guesswork and the costly trip to the dealership for programming. We handle the complex part, so you can perform a simple, straightforward replacement and get your Malibu’s reliable performance back.
Case Study: A Tricky Diagnosis
A customer brought in a 2009 Malibu with a complaint of intermittent, hard 1-2 shifts and occasionally getting stuck in 3rd gear (limp mode). No check engine light was on, but a scan revealed a stored history code, P0750 (Shift Solenoid A Malfunction). The owner had already replaced the solenoid with no change. After checking the wiring harness for continuity, I suspected the driver circuit within the TCM. We installed one of our pre-programmed T42 modules, and the problem was solved instantly. The vehicle shifted perfectly on the test drive. It’s a classic case where the TCM itself is the point of failure, not the components it controls.
Is Your Malibu Showing These Transmission Problems?
- ✔ Harsh, slamming, or erratic gear shifts.
- ✔ The vehicle is stuck in “limp mode” and won’t shift out of a single gear.
- ✔ Check Engine Light or Transmission Warning Light is illuminated with codes like P0700, P0750, or other solenoid-related DTCs.
- ✔ Delayed engagement when shifting from Park to Drive or Reverse.
- ✔ Poor acceleration and a sudden drop in fuel economy.
- ✔ Complete loss of communication with the transmission module.
Simple Steps to Install Your New TCM
For the 2006-2010 Malibu, this is a repair most DIYers can handle in their driveway in under 30 minutes. The module is located on the driver’s side frame rail, making it accessible from underneath the vehicle.
- Safety First: Disconnect the negative terminal from your vehicle’s battery to prevent any electrical shorts and to help reset the system.
- Locate the TCM: Safely raise the front of the vehicle and secure it with jack stands. The TCM is mounted to the LH (driver’s side) frame rail.
- Disconnect and Remove: Carefully unplug the electrical connectors. Note the locking tabs to avoid damage. Then, unbolt the module from its mounting bracket.
- Install the New Module: Bolt the new, pre-programmed TCM into place and securely reconnect the electrical harnesses. You should hear a ‘click’ as they lock.
- Final Steps: Reconnect the battery terminal. Start the vehicle and use a basic OBD2 scan tool to clear any lingering fault codes from the computer’s memory. Test drive to confirm smooth shifting.

Frequently Asked Questions
What does ‘VIN Programmed’ actually mean?
It means we load the module with your car’s unique Vehicle Identification Number (VIN) and the latest GM-approved software. This makes the TCM communicate perfectly with your car’s engine computer and other systems right out of the box, avoiding conflicts and the need for a dealer visit.
Do I need to send my old TCM back (core charge)?
No, there is absolutely no core charge. You can keep your old part or dispose of it without any hassle or extra fees.
Where is the TCM on a 2008 Chevy Malibu?
On the 2006-2010 Chevrolet Malibu, the Transmission Control Module is typically mounted on the left-hand (driver’s side) frame rail, accessible from under the car.
Will this fix a P0700 trouble code?
A P0700 code is a general fault request from the TCM to the main engine computer. While this module often resolves the underlying issue causing the P0700 (like a bad solenoid driver), you should always diagnose the specific codes stored within the TCM itself for a complete picture.
Is this a difficult part to install myself?
For most individuals with basic mechanical skills and tools, this is a very straightforward installation. Since it’s pre-programmed, the most difficult part of the job (the software) is already done for you.
