Expert Insight: Why VIN Programming is Non-Negotiable
For modern GM vehicles like your Cobalt, the TCM isn’t just a simple part—it’s a computer that communicates with the engine, brakes, and other systems.

This is the secret to a successful, lasting repair.
Frequently Asked Questions
What does ‘VIN Programmed’ mean for my Cobalt?
It means we load the module with the specific software and calibration file from General Motors that matches your vehicle’s unique Vehicle Identification Number (VIN). This ensures it works perfectly with your Cobalt’s engine and options, making the installation truly plug-and-play without needing a trip to the dealer.
Where is the TCM located on a 2006-2010 Chevrolet Cobalt?
On most Chevrolet Cobalts from this generation, the Transmission Control Module is located on the driver’s side of the engine bay, mounted to the LH strut tower. It’s a relatively accessible part for a straightforward installation.
Do I need any special tools to install this part?
No special tools are required. Basic hand tools (like a socket set) are all you need to unbolt the old module and install the new one. We do recommend disconnecting the battery before starting the installation to allow the vehicle’s systems to reset.
Will this fix my P0700 trouble code?
A P0700 code is a general transmission fault request from the TCM to the main engine computer. While this module often resolves the underlying issue causing the P0700, it’s important to have the vehicle scanned for more specific transmission codes (like P0750, P0753, etc.) to confirm the TCM is the fault. In most cases of electronic failure, this part is the correct fix.
