Fix Your Cobalt’s Shifting Problems for Good
Is your 2006-2010 Chevrolet Cobalt suffering from harsh shifting, getting stuck in gear, or showing a check engine light with transmission codes? These are classic signs of a failing Transmission Control Module (TCM). Don’t let a faulty module sideline your vehicle. This OEM-quality T42 TCM, service number 24234503, is the definitive solution to restore your transmission’s performance and reliability. It arrives at your door pre-programmed to your vehicle’s specific VIN, ensuring a seamless, plug-and-play installation without any expensive trips to the dealership.
From the Diagnostic Bay
We recently had a 2009 Cobalt in the shop that was stuck in limp mode (3rd gear only) and throwing a P0700 code. The owner had already spent money replacing shift solenoids based on a generic code reader’s suggestion, but the problem persisted. Our diagnostics pointed directly to the TCM, which was sending erratic signals. We installed this exact VIN-programmed T42 module. After a 20-minute installation and clearing the codes, the car shifted perfectly through all gears. This case highlights how correctly diagnosing the issue and using a properly programmed module saves time, money, and unnecessary repairs.
Is Your Cobalt Exhibiting These Transmission Problems?
A failing TCM can manifest in various ways, often being misdiagnosed as an internal transmission failure. Before considering a costly transmission replacement, check if you’re experiencing any of these common symptoms:
- ✔ Harsh, erratic, or delayed gear shifts that make driving uncomfortable and unpredictable.
- ✔ The vehicle enters “limp mode,” getting stuck in a single gear (usually 2nd or 3rd) to prevent further damage.
- ✔ Check Engine Light or Transmission Warning Light is illuminated on your dashboard.
- ✔ Diagnostic Trouble Codes (DTCs) such as P0700, P0750, or other solenoid-related codes are stored.
- ✔ Complete failure to upshift or downshift, leading to poor acceleration and high RPMs.
- ✔ A noticeable decrease in fuel economy as the engine and transmission work inefficiently.

Frequently Asked Questions
What is VIN programming and why do I need it?
VIN programming is the process of loading your vehicle’s unique 17-digit Vehicle Identification Number into the module. This allows the TCM to communicate correctly with your car’s engine computer and other systems, ensuring proper shift timing, pressure control, and overall performance. Without it, the module won’t work correctly.
Do I need to take my car to a dealership for installation?
No. Because this module comes pre-programmed to your VIN, it is a true plug-and-play solution. You or your local mechanic can perform the installation without needing specialized dealer equipment, saving you significant time and money.
Where is the TCM located on my 2006-2010 Chevrolet Cobalt?
On the 2006-2010 Cobalt, the Transmission Control Module (TCM) is typically found in the engine bay, mounted to the driver’s side (LH) strut tower.
Is there a core charge for this Cobalt Transmission Module?
No, there is absolutely no core charge. You are not required to return your old, faulty module, which simplifies the replacement process for you.
Will this part fix transmission error codes like P0700?
Yes. A faulty TCM is a very common cause for generic transmission codes like P0700, as well as more specific solenoid and sensor codes. Replacing a bad module with this pre-programmed unit will resolve these codes, provided the module was the root cause of the problem.
