Expert Insight: The Importance of VIN Programming
For modern GM vehicles like the Saturn Aura, the TCM isn’t just a simple component; it’s the brain of the transmission.

Our process of programming the module to your specific VIN before shipment ensures it communicates flawlessly with your car’s other computers right out of the box. This is the secret to a successful, hassle-free repair.
By choosing the correct, professionally programmed 2007-2009 Saturn Aura transmission control module, you’re not just buying a part; you’re investing in a reliable and lasting solution that restores your vehicle’s dependability. For your specific model, the TCM is typically located on the left-hand frame rail in the front of the engine compartment, making for a straightforward installation. Don’t let a faulty module dictate how your car drives. Take control and get your Aura shifting perfectly again.
Frequently Asked Questions
Do I need to have this module programmed by a dealer?
