Are you experiencing frustrating and unpredictable transmission problems? Harsh shifts, a car that refuses to shift out of gear, or a persistent check engine light can turn any drive into a stressful ordeal.

Common Symptoms & Your Solution
A failing TCM can manifest in several ways, often getting progressively worse. If you’re noticing any of the following, it’s a clear sign your module needs attention:
- Erratic or Harsh Shifting: Abrupt, jerky gear changes or a noticeable delay when the transmission engages.
- Stuck in Gear (Limp Mode): The vehicle may be stuck in 2nd or 3rd gear, a safety measure to prevent further damage.
- Warning Lights: A check engine light or specific transmission warning light is illuminated on your dash.
- Diagnostic Trouble Codes (DTCs): Common codes like P0700 (Transmission Control System Malfunction), P0750, or other solenoid-related faults are stored.
- Poor Performance: A sudden drop in fuel economy or a transmission that seems to be overheating.
This module is the direct-fit, plug-and-play answer to these issues. By installing our Programmed 2007-2009 Saturn Aura TCM, you are not just replacing a part; you are providing a complete, long-term fix that addresses the root cause of these common transmission failures.

Frequently Asked Questions
What is a TCM and what does it do?
The Transmission Control Module (TCM) is a computer that controls your automatic transmission. It reads data from various sensors in the engine and transmission to determine the perfect moment to shift gears, ensuring smooth operation, optimal performance, and fuel efficiency.
Is this part difficult to install?
No, installation is designed to be straightforward for someone with basic mechanical skills. The TCM is typically located in the engine compartment (e.g., on the frame rail or near the strut tower). The process involves disconnecting the battery, unplugging the electrical connectors, unbolting the old module, and installing the new one. No special programming tools are required.
Will this fix my specific error codes like P0700?
Yes, this module is specifically designed to resolve common transmission-related DTCs, including P0700 and various solenoid codes. Because it comes programmed with the latest software, it directly addresses the electronic faults that cause these codes to appear.
Do I need to send my old part back?
No. We do not require a core return for this part. You can keep your old module, which simplifies the process and saves you the time and expense of return shipping.
How do I know this is the right part for my vehicle?
You can confirm fitment by matching your vehicle’s year, make, and model to the compatibility list provided. The most accurate method is to match the service number on your existing TCM to one of the numbers listed, such as 24234274, 24252114, or 24234503. When you order, we will use your VIN to ensure perfect compatibility.
What should I do after installing the new TCM?
After installing the new module and reconnecting the battery, it’s a good practice to use a standard OBD2 scan tool to clear any old trouble codes stored in the vehicle’s main computer (ECU). The vehicle may then go through a brief re-learning period as it adapts to the new module, which is completely normal.
