Restore Peak Performance to Your Chevrolet Cobalt
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. This critical component is the brain of your automatic transmission, and when it fails, it can cause a cascade of frustrating and potentially damaging issues. This genuine quality GM T42 TCM, part number 24235753, is the definitive solution, pre-programmed to your vehicle’s specific VIN for a seamless, plug-and-play installation that restores the smooth, reliable performance you expect.
Expert Pro Tip
Before installing your new TCM, always disconnect the negative terminal of your vehicle’s battery for at least 15 minutes. This not only ensures your safety but also helps clear the old adaptive learning values from the vehicle’s powertrain computer. After installation, reconnect the battery and use a scan tool to clear any stored Diagnostic Trouble Codes (DTCs) for a fresh start.
Is Your Cobalt Showing Signs of a Failing TCM?
A faulty TCM can manifest in various ways, often starting as minor annoyances and escalating to major drivability problems. If you’re experiencing any of the following, it’s time to diagnose your module:
- ✔ Harsh Shifting: Abrupt, jerky, or clunky gear changes during acceleration or deceleration.
- ✔ Delayed Engagement: A noticeable pause when shifting from Park into Drive or Reverse.
- ✔ Limp Mode Activation: The vehicle gets stuck in a single gear (usually 2nd or 3rd) to prevent further damage, severely limiting speed.
- ✔ Warning Lights: The Check Engine Light or a specific transmission warning light is illuminated on your dashboard.
- ✔ Diagnostic Trouble Codes (DTCs): Common codes like P0700 (Transmission Control System Malfunction), P0750-P0758 (Shift Solenoid Errors), or other transmission-related codes are stored.
- ✔ Poor Fuel Economy: Inefficient shifting patterns cause the engine to work harder, leading to a sudden drop in MPG.
- ✔ Complete Failure to Shift: The transmission may refuse to shift up or down, regardless of speed or engine RPM.
The Technical Role of the 2006-2010 Cobalt Transmission Control Module
The Cobalt Transmission Control Module serves as the central command center for the 4-speed automatic transmission (like the 4L60E, 4L65E, or 4T45-E). It continuously analyzes data from various sensors, including vehicle speed, engine RPM, throttle position, and fluid temperature. Using this information, it precisely controls hydraulic pressure to activate shift solenoids, engage the torque converter clutch, and ensure every gear change is perfectly timed. A failing module disrupts this communication, leading to the symptoms listed above. Our replacement module restores this critical link, ensuring your transmission operates exactly as the manufacturer intended.

Frequently Asked Questions
What does a VIN-programmed TCM mean?
It means we load the module with the specific software and calibration files from General Motors that match your vehicle’s exact Vehicle Identification Number (VIN). This makes the part a direct, plug-and-play replacement without needing a trip to the dealer for expensive programming.
Do I need to take my car to a dealership after installing this part?
No. Our VIN programming service completely eliminates the need for post-installation programming at a dealership or repair shop, saving you time and money.
Will this fix a P0700 code on my Cobalt?
A P0700 code is a general fault code indicating the TCM has detected a problem. While this module often resolves the root cause (such as internal TCM failure), you should always diagnose any other accompanying codes (like solenoid codes) to ensure a complete repair.
Where is the TCM located on a 2006-2010 Chevy Cobalt?
On the Chevrolet Cobalt, the Transmission Control Module is typically located in the engine compartment, mounted on the driver’s side strut tower.
Is a core charge required for this module?
No, there is no core charge. You are not required to send your old, faulty module back to us, simplifying the repair process for you.
