Restore Flawless Shifting to Your Saturn Aura
Is your 2007, 2008, or 2009 Saturn Aura experiencing frustrating and unpredictable transmission issues? Problems like harsh shifting, getting stuck in gear, or an illuminated check engine light often point directly to a failing Transmission Control Module (TCM). The TCM is the electronic brain of your automatic transmission, responsible for managing every gear change, controlling torque converter lockup, and ensuring smooth, efficient operation. When it fails, it can mimic a catastrophic mechanical failure, leading to costly misdiagnoses. This OEM-quality T42 TCM, part number 24238856, is the definitive solution to restore your vehicle’s performance and drivability.
From the Diagnostic Bay
We recently had a 2008 Aura towed in with what the owner was convinced was a ‘blown transmission.’ It would slam into gear and often refused to shift past 2nd. Another shop had quoted them thousands for a complete transmission rebuild. Our first step was a full diagnostic scan, which revealed several solenoid circuit fault codes. Instead of immediately condemning the transmission, we inspected the TCM wiring and recommended replacing the module itself. After installing this VIN-programmed T42 module, the car shifted as smoothly as the day it left the factory. It was a massive save for the customer, proving that the problem was electronic, not mechanical.
Symptoms of a Failing Saturn Aura TCM
A faulty transmission module can manifest in various ways. If you’re noticing any of the following symptoms, it’s highly likely your TCM is the culprit:
- ✔ Erratic Shifting: Abrupt, harsh, or delayed gear changes that make driving uncomfortable and unpredictable.
- ✔ Stuck in Gear (Limp Mode): The vehicle may refuse to shift out of a single gear (often 2nd or 3rd) as a protective measure.
- ✔ Warning Lights: The Check Engine Light or a specific transmission warning light will illuminate on your dashboard.
- ✔ Diagnostic Trouble Codes (DTCs): A scan tool may show codes like P0700 (Transmission Control System Malfunction) or other solenoid-related faults (e.g., P0750, P0751).
- ✔ Poor Fuel Economy: Inefficient shifting and torque converter operation can lead to a noticeable drop in MPG.
- ✔ No Engagement: In severe cases, the transmission may fail to engage in Drive or Reverse altogether.

We use your vehicle’s Vehicle Identification Number (VIN) to flash the module with the latest, vehicle-specific software from General Motors. This ensures perfect communication between the TCM, the Engine Control Module (ECM), and all other vehicle systems right out of the box. No trips to the dealership, no extra programming fees, and no compatibility headaches. This 2007-2009 Aura Transmission Module is built to strict OEM standards, ensuring long-lasting reliability and performance, backed by our comprehensive one-year warranty.
Simple, Direct-Fit Installation
Designed for a straightforward installation, this module can be replaced with basic hand tools in under an hour. On the 2007-2009 Saturn Aura, the TCM is located on the front portion of the driver’s side (LH) frame rail. Simply disconnect the battery, unbolt the old unit, disconnect its electrical harnesses, and install the new one in its place. Once reconnected, your vehicle is ready to go. We also require no core charge, so you can keep your old part without the hassle of returning it.
Frequently Asked Questions
Do I need to have this module programmed by a dealer?
No. This module comes pre-programmed to your vehicle’s specific VIN. It is a true plug-and-play solution that does not require any additional programming or dealership visits after installation.
What is a ‘core charge’ and do you require one?
A core charge is a deposit that is returned to you when you send back your old part. We do not require a core charge for this module, saving you time and money. You can keep or dispose of your old part at your convenience.
Will this fix my specific transmission problem?
This module is a direct fix for issues caused by a faulty TCM, such as the symptoms listed above (erratic shifting, DTCs, limp mode). While it solves the vast majority of electronic transmission faults, it will not fix internal mechanical failures. We recommend having your vehicle professionally diagnosed if you are unsure of the cause.
Where is the TCM located on my 2008 Saturn Aura?
The Transmission Control Module on the 2007-2009 Saturn Aura is typically mounted on the driver’s side (LH) front frame rail in the engine compartment.
What tools are needed for installation?
Installation typically requires only basic hand tools, such as a socket set and ratchet to remove the mounting bolts and a tool to disconnect the negative battery terminal. No specialized equipment is needed.
