Is Your Saturn ION’s Transmission Acting Up?
Are you experiencing frustrating and unpredictable transmission problems like harsh, jerky shifts, delayed gear engagement, or a sudden check engine light? A failing Transmission Control Module (TCM) is often the culprit, leaving your vehicle unreliable and potentially stuck in a ‘limp mode’. This pre-programmed T42 Transmission Control Module is the definitive, hassle-free solution to restore your vehicle’s smooth operation and get you back on the road with confidence.
Common Symptoms & Your Solution
If your vehicle is exhibiting any of the following signs, a faulty TCM is the likely cause. This module is engineered to resolve these exact issues:
- Harsh, erratic, or delayed shifting
- Vehicle is stuck in one gear (limp mode)
- Transmission or Check Engine warning lights are on
- Diagnostic Trouble Codes (DTCs) such as P0700, P0750, or other solenoid-related codes
- Failure to upshift or downshift properly
- Poor fuel economy and transmission overheating
Installing this professionally programmed 2006-2007 Saturn ION transmission control module is the most effective way to permanently fix these problems and avoid costly, and often unnecessary, transmission repairs.

- ✔ OEM-Standard Quality: Built to meet or exceed original equipment specifications, this module ensures long-term reliability and durability for daily driving and demanding conditions.
- ✔ Cost-Effective Repair: Save hundreds of dollars compared to dealership prices for parts and labor. This is a smart, direct-fit solution for both DIY mechanics and professional shops.
- ✔ Guaranteed Performance: This unit is backed by our one-year replacement warranty.
Expert Technician’s Note: The Power of Pre-Programming
Modern transmissions are complex systems. The TCM acts as the brain, and it needs the right software—your vehicle’s VIN-specific calibration file—to function correctly. A generic or non-programmed module can cause more problems than it solves, leading to persistent codes and poor performance. Our VIN programming service loads the latest GM software updates onto your specific 2006-2007 Saturn ION transmission control module before it even ships, guaranteeing it works correctly right out of the box.
Don’t let a faulty TCM dictate your driving experience. By choosing the right part, you’re not just fixing a problem; you’re investing in your vehicle’s longevity and your own peace of mind. This 2006-2007 Saturn ION transmission control module is your direct path to a reliable repair.
Frequently Asked Questions
What does a Transmission Control Module (TCM) do?
The TCM is a computer that controls your automatic transmission. It gathers data from various sensors in the engine and transmission to control shift solenoids, regulate fluid pressure, and ensure smooth, efficient gear changes.
Is this part difficult to install?
Installation is generally straightforward for someone with basic mechanical skills. On most models, including the Saturn ION, it’s located in the engine compartment (often behind the LH strut tower) and can be swapped in under 30 minutes. Always disconnect the battery before starting the replacement.
Will this module require additional programming?
No. The main benefit of our service is that the module comes fully programmed to your vehicle’s VIN. It is ready for installation right out of the box, with no need for a scan tool or a visit to the dealership for further setup.
How do I know for sure if my TCM is failing?
Common signs include erratic shifting, getting stuck in gear (limp mode), and specific transmission-related diagnostic codes (like P0700). While other issues can cause similar symptoms, these are the classic indicators of a failing TCM.
What happens if I don’t replace a bad TCM?
Continuing to drive with a faulty TCM can lead to poor fuel efficiency, unpredictable vehicle behavior, and can eventually cause severe mechanical damage to your transmission due to incorrect fluid pressures and shifting patterns, resulting in a much more expensive repair.
Does this part fit other GM vehicles besides the Saturn ION?
Yes, this T42 TCM is compatible with a very wide range of 2006-2014 GM vehicles, including trucks, vans, SUVs, and sedans like the Chevrolet Silverado, Tahoe, Impala, GMC Sierra, Buick LaCrosse, and many others. Our programming ensures it works perfectly for your specific model.
