Is Your Saturn Vue’s Transmission Acting Up?
Are you experiencing frustrating and unpredictable shifting, a sudden loss of power, or a persistent check engine light in your 2007-2010 Saturn Vue? A faulty Transmission Control Module (TCM) is often the culprit behind these unnerving issues, disrupting your daily drive and leaving you concerned about costly repairs. This expertly prepared Programmed T42 Transmission Control Module is the definitive, hassle-free solution to restore your vehicle’s performance and your peace of mind.
Common Symptoms & Your Solution
A failing TCM can manifest in several ways. If you’re noticing any of the following, it’s a clear sign your module needs attention:
- Harsh or Erratic Shifting: Abrupt, jerky gear changes or a noticeable delay when the transmission shifts.
- Stuck in Gear / Limp Mode: The vehicle refuses to shift out of a single gear (often 2nd or 3rd) to protect the transmission from further damage.
- Warning Lights: The Check Engine Light or a dedicated transmission warning light is illuminated on your dashboard.
- Diagnostic Trouble Codes (DTCs): You may find codes such as P0700, which indicates a general transmission fault, or specific solenoid codes like P0750.
- Poor Performance: A noticeable decrease in fuel economy, a feeling of sluggishness, or transmission overheating.
This module is engineered to be the direct solution to these problems. By replacing your old, failing unit with this pre-programmed T42 TCM, you are directly addressing the electronic brain of your transmission, ensuring all shifting commands are executed precisely as the manufacturer intended.

Expert Insight: The Power of VIN Programming
Why is VIN programming so important? Your vehicle’s transmission has unique characteristics and learns your driving habits over time. A generic, non-programmed module can’t account for these specifics, often leading to persistent shifting issues or even new error codes. Our process flashes the module with the latest GM software updates tailored specifically to your VIN, ensuring it communicates flawlessly with your vehicle’s engine computer and other systems from the moment it’s installed. This is the key to a successful, one-time repair.
Frequently Asked Questions
Do I need to program this module?
No. This Programmed T42 Transmission Control Module is delivered to you fully programmed to your vehicle’s VIN. It is ready for installation immediately upon arrival, saving you time and the cost of a dealership visit.
Where is the T42 TCM located on my vehicle?
The location varies by model. On many vehicles like the Saturn Vue, it’s in the engine compartment on the LH (driver’s) side. For trucks like the Silverado/Sierra, it’s often next to the battery. For sedans like the Impala, it can be under the air cleaner box. Always consult a repair manual for your specific vehicle for the exact location.
Is this a difficult part to install?
For someone with basic mechanical skills, the installation is straightforward and typically takes less than 30 minutes. It involves disconnecting the battery, unplugging the electrical connectors, unbolting the old module, and installing the new one. We recommend using a scan tool to clear any stored DTCs after installation is complete.
How do I know for sure that my TCM is the problem?
Common symptoms like erratic shifting, being stuck in limp mode, and specific transmission-related error codes (like P0700) are strong indicators of a failing TCM. While a professional diagnosis is always best, these symptoms, especially when appearing together, point directly to the TCM as the likely source of the issue.
Will this fit vehicles other than the 2007-2010 Saturn Vue?
Yes, this T42 TCM is compatible with a very wide range of 2006-2014 General Motors vehicles equipped with 4-speed automatic transmissions like the 4L60E and 4L65E. This includes many Chevrolet, GMC, Buick, Cadillac, Pontiac, Hummer, and Saab models. Please check the detailed fitment list on this page to confirm compatibility with your vehicle.
