Is your 2007-2010 Saturn Vue suffering from frustrating and unpredictable transmission behavior? If you’re dealing with harsh shifts, getting stuck in gear, or seeing that dreaded check engine light, you’re not alone. As a technician with over two decades of experience, I’ve seen countless GM vehicles sidelined by a faulty Transmission Control Module (TCM). This isn’t just an annoyance; it’s a reliability issue that can leave you stranded. The good news is that the fix is often simpler and more affordable than you think.
This T42 Transmission Control Module, part number 24234274, is the definitive solution for restoring the crisp, smooth shifting your vehicle had when it was new. The most significant benefit? It arrives at your door fully programmed to your vehicle’s specific VIN. This eliminates the need for expensive dealership visits for programming, turning a complex repair into a straightforward, plug-and-play job you can do right in your driveway.
From the Diagnostic Bay
I remember a customer bringing in a 2008 Saturn Vue with classic symptoms: it would slam into gear from a stop and occasionally refuse to shift past 2nd gear (limp mode). He was worried he was facing a complete transmission rebuild, a repair that can run into thousands. After connecting my scan tool, I pulled a P0700 (Transmission Control System Malfunction) and a few solenoid-specific codes. Instead of jumping to conclusions, we checked the basics. Fluid was clean, and wiring was intact. The culprit was the TCM. We installed a VIN-programmed module just like this one, and in under an hour, the Vue was shifting perfectly. He saved a fortune and drove away with a reliable vehicle, all thanks to replacing the right part.
Is Your Saturn Vue Showing These Telltale Signs?
A failing TCM doesn’t always mean total failure. It often starts with intermittent issues. If you notice any of the following, it’s time to consider a replacement:
- ✔ Harsh, clunky, or erratic gear shifts.
- ✔ The vehicle is stuck in ‘limp mode’ and won’t shift out of 2nd or 3rd gear.
- ✔ Check Engine Light or Transmission Warning Light is illuminated.
- ✔ Your scan tool shows Diagnostic Trouble Codes (DTCs) like P0700, P0750, or other transmission-related solenoid codes.
- ✔ Delayed engagement when shifting from Park to Drive or Reverse.
- ✔ A noticeable drop in fuel economy due to inefficient shifting.
Your Straightforward 30-Minute Installation Guide
Replacing your 2007-2010 Vue Transmission Module is a job most DIYers can handle with basic tools. Because this unit is pre-programmed, there are no complicated steps.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery before starting any electrical work.
- Locate the Module: On the Saturn Vue (2.4L), the TCM is typically found in the left-hand (driver’s side) front of the engine compartment. Check near the strut tower or under the air cleaner box.
- Disconnect and Remove: Carefully unplug the electrical connectors. Press the release tabs firmly to avoid breaking them. Then, unbolt the old module from its mounting bracket.
- Install the New Module: Bolt the new, pre-programmed TCM into place and securely reconnect the electrical harnesses. You should hear a ‘click’ as they lock in.
- Final Steps: Reconnect the battery terminal. While the module is plug-and-play, it’s best practice to use a basic OBD2 scan tool to clear any stored fault codes from the vehicle’s memory. Start the car and take it for a test drive to confirm the shifting issues are resolved.

Frequently Asked Questions
Does this module really not need to be programmed by a dealer?
That’s correct. We program the module to your vehicle’s VIN before shipping it. This means it’s ready for installation right out of the box, saving you time and money.
Is there a core charge for my old part?
No, there is no core charge. You can keep your old part or dispose of it without the hassle of sending it back.
What tools do I need for the installation?
You’ll typically only need basic hand tools, such as a socket set to remove the mounting bolts and potentially a small flathead screwdriver to help release the connector tabs.
What if I replace the TCM and still have problems?
While this module fixes the most common cause of these symptoms, transmission issues can be complex. If problems persist, it could indicate a mechanical issue within the transmission or a problem with the wiring harness. We recommend double-checking all connections and ensuring the transmission fluid is at the correct level and in good condition.
