Restore Peak Transmission Performance in Your Saturn ION
Is your 2006-2007 Saturn ION experiencing frustrating transmission problems like harsh, erratic shifting, getting stuck in gear, or a persistent check engine light? These are classic signs of a failing Transmission Control Module (TCM). Don’t let a faulty module sideline your daily driver.

Common Symptoms & Your Solution
A failing TCM can cause a cascade of issues that affect your vehicle’s drivability and safety. If you’re noticing any of the following, it’s time for a replacement:
- Abrupt, jerky, or delayed gear shifts.
- The vehicle enters “limp mode,” refusing to shift out of a single gear.
- Transmission or Check Engine warning lights are illuminated on your dash.
- Diagnostic Trouble Codes (DTCs) such as P0700, P0750, or other solenoid-related faults are present.
- A noticeable decrease in fuel economy or signs of the transmission overheating.
This module is engineered to be the direct, reliable fix for these problems, restoring the precise electronic control your transmission needs to operate as designed. By installing our pre-programmed 2006-2007 Saturn ION transmission control module, you’re not just replacing a part—you’re restoring your vehicle’s original performance and reliability.

Expert Insight: Why VIN Programming is Non-Negotiable
Many sellers offer generic, unprogrammed modules, leaving the most critical step to you. An unprogrammed TCM is just a metal box; it cannot communicate with your vehicle’s other computers. Our process is different. We flash the module with the latest GM-certified software specific to your VIN. This ensures all shift points, pressure controls, and diagnostic parameters are perfectly matched to your Saturn ION’s factory settings. This isn’t just a convenience—it’s the key to a successful and lasting repair, preventing the common compatibility issues that plague generic replacements.
Frequently Asked Questions
Do I need to have this module programmed by a dealer?
No. We handle all the programming for you. Simply provide your vehicle’s VIN during checkout, and the module will arrive ready for immediate installation. This saves you a trip to the dealership and avoids hundreds of dollars in programming fees.
Is this installation difficult to do myself?
For most DIYers with basic tools, this is a straightforward job. The TCM on a 2006-2007 Saturn ION is typically located behind the LH strut tower. The process involves disconnecting the battery, unplugging the electrical connectors, unbolting the old module, and installing the new one. It can often be completed in under 30 minutes.
Will this fix my specific transmission error codes?
This module is the correct solution for a wide range of transmission-related DTCs, especially communication errors (like P0700) and solenoid circuit faults. If your diagnostics point to a faulty TCM, this part is designed to clear those codes once installed and the system is reset.
Is this the correct part for vehicles other than a Saturn ION?
Yes, this T42 TCM is compatible with a wide array of 2006-2014 GM vehicles. While this listing is optimized for the 2006-2007 Saturn ION transmission control module, you can verify fitment for other models like the Chevrolet Cobalt, HHR, Pontiac G6, and more by checking the extensive compatibility list on our site or contacting our support team.
