Is Your Chevrolet Cobalt Experiencing Transmission Problems?
If your 2006-2010 Chevrolet Cobalt is suffering from erratic shifting, getting stuck in gear, or has an illuminated check engine light, a failing Transmission Control Module (TCM) is the most likely culprit. The TCM is the electronic brain of your automatic transmission, responsible for controlling shift points, torque converter clutch engagement, and line pressure. When it fails, it can mimic the symptoms of a catastrophic mechanical failure, leading to drivability issues and diagnostic headaches. This genuine OEM-quality T42 TCM, service number 24234274, is the definitive solution to restore your vehicle’s performance and reliability.
From the Diagnostic Bay
We recently had a 2008 Cobalt come into the shop with the classic complaint: “It slams into gear and won’t shift past second.” The owner was worried they needed a complete transmission rebuild, which would have cost thousands. After connecting our scan tool, we pulled a P0752 code for ‘Shift Solenoid A Stuck On’. While this can sometimes be a solenoid issue, experience with these platforms points directly to the TCM. Instead of a costly internal repair, we installed a VIN-programmed 2006-2010 Cobalt TCM. After a 20-minute installation and clearing the codes, the car shifted perfectly. The customer saved a fortune and was back on the road the same day. It’s a prime example of how diagnosing the electronics first can prevent unnecessary and expensive mechanical work.
Why Choose Our Programmed 2006-2010 Cobalt TCM?
This isn’t just a replacement part; it’s a complete, ready-to-install solution. We take the guesswork and extra expense out of the repair by pre-programming the module to your vehicle’s specific Vehicle Identification Number (VIN). This critical step ensures that the TCM has the latest GM software and is perfectly calibrated for your Cobalt’s powertrain configuration. You can bypass the costly programming fees and scheduling delays at a dealership. Simply install the module, connect the harnesses, and you’re ready to go.

Frequently Asked Questions
What does a Transmission Control Module do on a Chevy Cobalt?
The TCM acts as the central computer for your automatic transmission. It collects data from various sensors (like vehicle speed and engine RPM) to make precise decisions about when to shift gears, control fluid pressure, and lock the torque converter for optimal performance and fuel efficiency.
Is this TCM difficult to install myself?
For the 2006-2010 Cobalt, the TCM is typically located on the driver’s side strut tower in the engine compartment, making it very accessible. The installation process is straightforward for someone with basic mechanical skills and can usually be completed in under 30 minutes. Simply disconnect the battery, unplug the old module, unbolt it, and install the new one in its place.
What does “VIN Programmed” actually mean for me?
“VIN Programmed” means we load the module with your vehicle’s specific software from GM before we ship it. This makes the installation plug-and-play. You will not need to take your car to a dealership for expensive programming, saving you time and money.
Will this module fix a P0700 trouble code?
A P0700 code is a general fault code indicating that the TCM has detected a problem and has requested the check engine light be turned on. While the P0700 itself doesn’t specify the issue, it is very often triggered by an internal failure of the TCM. Replacing the module is a common and effective fix for this code, especially when accompanied by other transmission-specific codes.
Do I need to send my old TCM back (core charge)?
No, there is no core charge required for this part. You can keep your old module or dispose of it at your convenience without any additional fees or hassle.
