Experiencing Shifting Problems with Your Saturn Aura?
If your 2007, 2008, or 2009 Saturn Aura is suffering from harsh, delayed, or erratic shifting, you’re not alone. In my 20+ years as a technician, I’ve seen countless GM vehicles come into the shop with these exact issues. Often, the root cause isn’t a catastrophic transmission failure, but a faulty Transmission Control Module (TCM). This T42 TCM, part number 24235753, is the definitive solution, arriving pre-programmed to your vehicle’s VIN for a true plug-and-play repair.
The Technician’s Perspective: Why a Programmed TCM is Critical
A customer’s 2008 Saturn Aura came in last week with a check engine light, a P0700 (Transmission Control System Malfunction) code, and a nasty habit of slamming into gear. The owner was worried about needing a full transmission rebuild. After a quick diagnostic check confirmed the TCM was the culprit, we installed one of our pre-programmed modules. The difference was immediate. The car shifted like it just rolled off the factory floor. This is the power of a correctly programmed moduleโit restores the precise communication needed for smooth operation, saving you from a costly and unnecessary trip to the dealership.
Common Symptoms of a Failing 2007-2009 Aura Transmission Module
A failing TCM can manifest in several ways. If you’re noticing any of the following, it’s a strong indicator that your module needs replacement:
- โ Harsh, banging shifts or delayed gear engagement.
- โ The vehicle is stuck in “limp mode” (usually 2nd or 3rd gear).
- โ An illuminated Check Engine Light or Transmission Warning Light.
- โ Diagnostic Trouble Codes (DTCs) such as P0700, P0750, or other solenoid-related faults.
- โ A complete loss of shifting ability or poor fuel economy.
Plug-and-Play Installation: No Dealer Visit Required
This isn’t a job that requires a professional lift or specialized tools. For your Saturn Aura, the installation is straightforward. You can have your car back to normal in under an hour.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery before starting any electrical work.
- Locate the TCM: On your 2007-2009 Saturn Aura, the TCM is mounted on the front of the left-hand (driver’s side) frame rail.
- Disconnect and Remove: Carefully unplug the electrical connectors from the old module. Then, unbolt the module from its mounting bracket.
- Install the New Module: Bolt the new, pre-programmed TCM into place and securely reconnect the electrical harnesses. Ensure they click into place.
- Final Steps: Reconnect the battery terminal. While the module is programmed, it’s always a good practice to use a basic scan tool to clear any stored fault codes from the vehicle’s memory.
Expert Pro Tip: Inspect Your Connectors
Before plugging in your new module, take a moment to closely inspect the vehicle’s wiring harness connectors. Look for any signs of corrosion (green or white powder), moisture, or bent pins. A poor connection is a common cause of intermittent issues and can damage a new module. Use a small brush and electrical contact cleaner to ensure the connection is perfect.
