Restore Flawless Shifting to Your Chevrolet Cobalt
Is your 2006-2010 Chevrolet Cobalt suffering from erratic shifting, getting stuck in gear, or displaying a check engine light? These are classic signs of a failing Transmission Control Module (TCM). The TCM is the electronic brain of your automatic transmission, responsible for orchestrating every gear change, managing torque converter lockup, and ensuring smooth, efficient operation. When it fails, it can make your vehicle unreliable and frustrating to drive. This genuine quality T42 TCM, service part number 24235340, is the definitive solution to restore your vehicle’s performance and dependability.
From the Diagnostic Bay
We recently had a 2008 Cobalt towed in with a classic complaint: “It won’t shift out of 2nd gear.” The check engine light was on, and the driver was worried about a costly transmission rebuild. Our scan tool pulled a P0700 (Transmission Control System Malfunction) and several solenoid-specific codes. Instead of jumping to the worst-case scenario, we checked the TCM. After confirming power and ground, we identified the internal module as the culprit. We installed one of our VIN-programmed T42 modules, cleared the codes, and took it for a test drive. The car shifted perfectly through all gears, just like it did from the factory. The customer was back on the road in under an hour, having avoided a thousand-dollar repair bill.
Symptoms of a Failing Cobalt TCM
A faulty TCM can manifest in various ways, often starting as intermittent issues before becoming a constant problem. If you’re experiencing any of the following, your TCM is the likely cause:
- ✔ Harsh or Delayed Shifting: The car may slam into gear, hesitate before shifting, or feel like it’s slipping between gears.
- ✔ Stuck in Limp Mode: The vehicle may be stuck in a single gear (usually 2nd or 3rd) to prevent further damage, resulting in poor acceleration and high RPMs at cruising speed.
- ✔ Warning Lights: The Check Engine Light or a specific transmission warning light will illuminate on your dashboard.
- ✔ Diagnostic Trouble Codes (DTCs): Common codes include P0700, P0750, and other transmission solenoid or sensor-related faults.
- ✔ Poor Fuel Economy: Inefficient shifting and torque converter operation can lead to a noticeable drop in MPG.
- ✔ No Communication: In severe cases, a scan tool may be unable to communicate with the TCM, indicating a complete failure.

Frequently Asked Questions
What does a TCM do on a 2006-2010 Chevy Cobalt?
The Transmission Control Module (TCM) acts as the computer for your automatic transmission. It uses data from various sensors to control shift points, line pressure, and torque converter lockup, ensuring your Cobalt drives smoothly and efficiently.
What does ‘VIN Programmed’ mean?
