- Failure to upshift or downshift properly
- Noticeable decrease in fuel economy
This module is the direct, effective solution. It arrives pre-programmed to your vehicle’s specific VIN, ensuring it communicates perfectly with your ION’s powertrain system right out of the box, resolving these frustrating issues without a trip to the dealer.

Expert Insight: Why VIN Programming is Non-Negotiable
As a mechanic with over 20 years of experience, I can’t stress this enough: for modern GM vehicles, VIN programming isn’t a luxury, it’s a necessity. The TCM is the ‘brain’ of your transmission, and it needs to speak the exact same language as your car’s main computer (the ECM). A generic, non-programmed module is like a translator who only knows half the words. It will cause shifting errors, incorrect performance, and can even damage your transmission over time. Our process ensures this 2006-2007 Saturn ION TCM has the latest GM software and is precisely matched to your car’s factory settings, guaranteeing a successful and lasting repair.
Frequently Asked Questions
Do I need to have this module programmed by a dealer?
No. This is the biggest benefit of our service. We pre-program the module using your vehicle’s VIN before it ships. It will arrive ready for a plug-and-play installation, saving you time and the high cost of dealership programming.
Where is the TCM located on my 2006-2007 Saturn ION?
On the Saturn ION models from 2006-2007, the Transmission Control Module is typically located in the engine compartment, behind the driver’s side (LH) strut tower.
Will this fix my car being stuck in ‘limp mode’?
Yes, in most cases. ‘Limp mode’ is a protective measure triggered by the computer when it detects a serious transmission fault. A failing TCM is a very common cause of this issue. Replacing it with this correctly programmed unit should restore full gear functionality.
What tools are needed for installation?
Installation is generally straightforward and requires basic hand tools, such as a socket set and ratchet. The most important step is to disconnect the vehicle’s battery before you begin to ensure the system resets properly. After installation, it’s a good practice to clear any remaining codes with a basic OBD-II scan tool.
