Restore Flawless Shifting to Your Saturn Aura
If you’re dealing with the frustration of a transmission that won’t shift correctly, slams into gear, or has left you stranded in limp mode, you’ve come to the right place. As a technician with over two decades of experience, I’ve seen countless GM vehicles, including the 2007-2009 Saturn Aura, suffer from these exact issues. The culprit is almost always a failing Transmission Control Module (TCM). This isn’t just an inconvenience; it’s a critical failure that affects your car’s performance, fuel economy, and safety. This OEM-quality T42 TCM, part number 24239224, is the definitive solution, arriving pre-programmed to your vehicle’s VIN for a hassle-free, direct-fit replacement.
A Technician’s Notebook: The Case of the Hesitant HHR
A customer brought in a Chevy HHR with the classic symptoms—a harsh 1-2 shift that felt like being rear-ended and intermittent refusal to shift out of 2nd gear. The check engine light was on, and my scan tool pulled a P0700 (Transmission Control System Malfunction) and a P0752 (Shift Solenoid ‘A’ Stuck On). While the solenoid code pointed to a specific part, my experience screamed ‘TCM’. These T42 modules are notorious for internal circuit failures that send false signals, making you chase perfectly good solenoids. Instead of a complex internal transmission repair, we replaced the externally mounted TCM with a VIN-programmed unit. In 30 minutes, the car was shifting like new, all codes were gone, and the customer avoided a costly, unnecessary transmission teardown. This 2007-2009 Aura Transmission Control Module solves the exact same problem.
Is Your Saturn Showing These Telltale Signs?
A faulty TCM doesn’t heal itself; it only gets worse. If you recognize any of these symptoms, it’s time for a replacement.
- âś” Harsh, erratic, or delayed gear shifts.
- âś” Vehicle is stuck in one gear (often called ‘limp mode’).
- âś” Check Engine Light or Transmission Warning Light is illuminated.
- âś” Diagnostic Trouble Codes (DTCs) are present, such as P0700, P0750-P0758, or other solenoid-related faults.
- âś” A sudden drop in fuel efficiency.
- âś” The transmission seems to slip between gears or fails to engage completely.
DIY-Friendly Installation in Under an Hour
One of the biggest advantages of this module is that it’s designed for a straightforward installation, saving you hundreds in labor costs. For the Saturn Aura, the process is simple.
- Safety First: Disconnect the negative terminal from your vehicle’s battery to prevent any electrical shorts and to help reset the system.
- Locate the Module: On your 2007-2009 Saturn Aura, the TCM is typically mounted on the front left-hand (driver’s side) frame rail.
- Disconnect and Remove: Carefully unclip the electrical connectors. Press the release tabs firmly and pull straight out. Then, unbolt the module from its mounting bracket.
- Install the New Module: Bolt the new, pre-programmed TCM into place. Reconnect the electrical harnesses, ensuring they click securely into position.
- Final Steps: Reconnect the battery terminal. While our programming handles the critical setup, it’s always best practice to use a basic OBD2 scan tool to clear any stored fault codes from the vehicle’s memory.

Frequently Asked Questions
What does ‘VIN Programmed’ actually mean for me?
It means we load your vehicle’s specific Vehicle Identification Number (VIN) and the latest GM software onto the module before we ship it. This makes it a true plug-and-play part. You can install it in your driveway without needing an expensive trip to the dealership for programming.
Will this fix a P0700 trouble code?
Yes. A P0700 code is a general fault code indicating the TCM has detected a problem. In many cases, a failing TCM is the root cause, and replacing it with this pre-programmed unit will resolve the code and the underlying issue.
Do I need any special tools for installation?
No special tools are required. Basic hand tools, such as a socket set to remove the mounting bolts, are all you should need. An OBD2 scanner is recommended for clearing codes but is not always necessary.
Is there a core charge for my old part?
Absolutely not. We do not require you to send your old, faulty module back. This saves you the hassle and cost of a core return.
How do I know this is the right part for my car?
The best way is to match the part number 24239224 from your original module. You can also use our vehicle fitment guide or contact our expert support team with your VIN, and we’ll guarantee you get the correct part.
What kind of warranty is included?
This module is backed by our one-year, hassle-free warranty, giving you confidence and peace of mind in your repair.
