Restore Smooth, Reliable Shifting to Your Saturn Aura
If your 2007-2009 Saturn Aura is suffering from harsh shifts, getting stuck in gear, or throwing transmission-related check engine light codes, a failing Transmission Control Module (TCM) is the most common cause. As a technician with over two decades of experience, I’ve seen countless GM vehicles, including the Aura, come into the shop with these exact issues. The TCM is the brain of your automatic transmission, and when it fails, it can make your car feel unpredictable and unsafe to drive. This replacement T42 TCM, part number 24240449, is the definitive solution to get your vehicle operating like new again.
We take the guesswork and high cost out of the repair by pre-programming this module to your car’s specific Vehicle Identification Number (VIN). This means you can skip the expensive trip to the dealership for programming. It arrives at your door ready for a true plug-and-play installation, immediately resolving communication errors and restoring the precise electronic control your transmission needs for optimal performance and fuel efficiency. This isn’t just a part; it’s a complete, hassle-free fix for your 2007-2009 Aura TCM problems.
A Technician’s Notebook: The P0752 Code That Wasn’t a Solenoid
A customer brought in a 2008 Saturn Aura, frustrated because he had already replaced the ‘A’ shift solenoid twice, but the P0752 (Shift Solenoid ‘A’ Stuck On) code kept returning, and the car was stuck in limp mode. He was convinced the transmission was shot. On the scan tool, I could see the command to the solenoid was erratic. Instead of starting a costly transmission teardown, I checked the TCM. After swapping in a known-good programmed module, the commands normalized instantly, and the car shifted perfectly. The original TCM had an internal fault, sending faulty signals. This highlights why replacing a faulty 2007-2009 Aura TCM is often the root fix, saving hundreds in unnecessary labor and parts.
Is Your Saturn Aura Showing These Telltale Signs?
- ✔ Abrupt, harsh, or jerky gear changes.
- ✔ The vehicle feels stuck in one gear (often called “limp mode”).
- ✔ Delayed engagement when shifting from Park to Drive or Reverse.
- ✔ Illumination of the Check Engine Light or Transmission Warning Light.
- ✔ Diagnostic Trouble Codes (DTCs) stored, such as P0700, P0750, P0752, or other solenoid-related faults.
- ✔ Complete loss of upshifting or downshifting capabilities.
- ✔ A noticeable decrease in fuel economy due to inefficient shifting.
A Straightforward Guide to Installation
- ✔ Safety First: Disconnect the negative terminal from your vehicle’s battery to prevent electrical shorts and reset the system.
- ✔ Locate the TCM: On the Saturn Aura, the TCM is typically found on the front of the left-hand frame rail in the engine compartment.
- ✔ Disconnect and Remove: Carefully unplug the electrical connectors from the old module. Then, unbolt the module from its mounting bracket.
- ✔ Install the New Module: Mount your new, pre-programmed TCM in place and tighten the bolts. Reconnect the electrical connectors, ensuring they click securely into place.
- ✔ Reconnect and Verify: Reconnect the negative battery terminal. Start the vehicle and allow it to idle for a few minutes. Use a basic OBD2 scan tool to clear any lingering fault codes from the memory.
- ✔ Test Drive: Take the vehicle for a short drive to confirm that shifting is smooth and all warning lights are off. The transmission will perform a brief re-learn process.

Frequently Asked Questions
What is VIN programming and why do I need it?
