Expert Insight: Why VIN Programming is Non-Negotiable
From over 20 years of experience, I can tell you that on modern GM vehicles, the TCM isn’t just a simple computer—it’s part of a complex network. It constantly communicates with the Engine Control Module (ECM) and other vehicle systems. A generic, non-programmed module will cause communication errors, leading to the same shifting problems you’re trying to fix, or worse, a no-start condition. Our VIN programming ensures the TCM has the correct digital “handshake” for your specific Saturn Aura, guaranteeing it works correctly from the moment you plug it in.
Don’t let a bad module sideline your car. By choosing the correct, pre-programmed 2007-2009 Saturn Aura transmission control module, you are making a smart investment in your vehicle’s longevity and your own peace of mind. This part is also a direct replacement for service numbers 24252114, 24234503, 24242391, and many others, ensuring wide compatibility.

Will this module require any additional programming?
No. This 2007-2009 Saturn Aura transmission control module is delivered fully programmed to your vehicle’s VIN. It is a true plug-and-play solution, requiring no further dealership visits for software installation.
Where is the TCM located on my Saturn Aura?
On the 2007-2009 Saturn Aura, the transmission control module is typically located on the front of the left-hand frame rail in the engine compartment. Always disconnect the vehicle’s battery before starting the replacement.
Is this part difficult to install?
For someone with basic mechanical skills, the installation is straightforward and usually takes less than 30 minutes. It involves disconnecting the battery, unplugging the electrical connectors from the old module, unbolting it, and then installing the new one in the reverse order.
How do I know for sure that my TCM is the problem?
While the symptoms listed above are strong indicators, a definitive diagnosis is best made with a professional scan tool. Common fault codes like P0700 (Transmission Control System Malfunction) or specific solenoid codes point directly to a failing TCM or related wiring.
What happens if I don’t replace a bad TCM?
Continuing to drive with a faulty TCM can lead to severe and expensive mechanical damage to your transmission. Erratic shifting and incorrect line pressure can burn out clutches and cause catastrophic internal failure, turning a relatively simple electronic repair into a complete transmission rebuild.
Is there a core charge for this part?
No, we do not require you to return your old module. There is no core charge associated with this purchase, which simplifies the process for you.
