Restore Smooth Shifting to Your Saturn Vue
If your 2007-2010 Saturn Vue is suffering from jerky shifting, getting stuck in gear, or has the check engine light on, a failing Transmission Control Module (TCM) is the most likely culprit. As a mechanic with over two decades of experience, I’ve seen these symptoms countless times. A faulty TCM can make your daily drive frustrating and can even lead to more significant transmission damage if ignored. This T42 Transmission Control Module, part number 24256960, is the definitive, reliable solution to get your vehicle driving like new again.
The key to this part’s effectiveness is our professional VIN programming service. Before we ship it, we flash the module with your vehicle’s specific VIN and the latest GM software updates. This means it arrives ready for a true plug-and-play installation, eliminating the need for an expensive trip to the dealership for programming. This is the same process we use in our own shop to guarantee a perfect fix, saving our customers time and money. For any DIY mechanic or professional, this is the most efficient way to solve TCM-related issues on a wide range of GM vehicles.
Case Study: A Tricky Diagnosis
A customer brought in a 2009 Saturn Vue 2.4L with a classic complaint: it would randomly refuse to shift out of 2nd gear and the transmission warning light was on. They had already replaced a shift solenoid based on a generic code reading, but the problem persisted. After connecting my professional scan tool, I saw the dreaded P0700 (Transmission Control System Malfunction) code, a general indicator that the TCM has detected a fault. Digging deeper, I found intermittent communication loss codes with the TCM. Instead of chasing electrical ghosts, experience pointed directly to the module itself. We installed one of our VIN-programmed T42 TCMs. The installation took less than 30 minutes, and after a quick battery disconnect to clear the memory, the car shifted perfectly. The customer was thrilled to have a reliable vehicle back without the dealership’s high quote. This is a testament to how a quality, correctly programmed 2007-2010 Vue TCM is often the direct solution.
Is Your GM Vehicle Showing These Symptoms?
- ✔ Harsh, erratic, or delayed gear shifts that make driving uncomfortable.
- ✔ The vehicle is stuck in “limp mode,” often in 2nd or 3rd gear, with limited power.
- ✔ Check Engine Light or Transmission Warning Light is illuminated on the dash.
- ✔ Diagnostic Trouble Codes (DTCs) are present, such as P0700, P0750, or other solenoid-related faults.
- ✔ A complete failure to upshift or downshift, leading to poor acceleration and fuel economy.
- ✔ Intermittent loss of communication with the transmission module.
A Straightforward Guide to Installation
Replacing the TCM is a job most DIYers can handle in their own garage. For the 2007-2010 Saturn Vue, the module is typically located in the left-hand (driver’s side) front of the engine compartment. The process is simple and requires basic hand tools.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery before starting any electrical work. This prevents short circuits and helps reset the vehicle’s computer systems.
- Locate the Module: On your Vue, find the TCM in the LH front engine compartment. It’s a small metal box with electrical connectors. On other GM models, it could be near the battery, on the strut tower, or under the air cleaner box.
- Disconnect and Remove: Carefully unplug the electrical harnesses from the old TCM. Then, unbolt the module from its mounting bracket and remove it from the vehicle.
- Install the New Module: Bolt the new, pre-programmed TCM into place. Securely reconnect the electrical harnesses, ensuring they click into place to form a solid connection.
- Final Steps: Reconnect the negative battery terminal. Start the vehicle and let it idle for a few minutes. While our programming resolves most issues, it’s good practice to use a basic OBD2 scan tool to confirm no old fault codes remain.

Frequently Asked Questions
What exactly is VIN programming and why do I need it?
VIN programming is the process of loading your vehicle’s unique Vehicle Identification Number and the latest factory software onto the module. This ensures the TCM communicates perfectly with your vehicle’s engine computer and other systems, controlling shift points and pressures exactly as the manufacturer intended. It makes the part truly plug-and-play and avoids a mandatory, costly programming session at a dealership.
Will this part fix a P0700 trouble code?
A P0700 code is a general alert from the TCM. In many cases, a failing TCM is the root cause, and replacing it with our programmed unit will resolve the issue and allow the code to be cleared. However, P0700 can also be triggered by other transmission problems, so a full diagnosis is always recommended if you’re unsure.
Do I need to return my old TCM? Is there a core charge?
No, there is absolutely no core charge for this part. You can keep your old module or dispose of it at your convenience, making the transaction simple and hassle-free.
Is this a difficult part to install for a DIYer?
Not at all. For most vehicles, including the Saturn Vue, this is one of the easier electronic components to replace. It’s typically located in the engine bay and held on by a few bolts. With basic tools and our plug-and-play programming, most people can complete the job in under 30 minutes.
What kind of warranty comes with this module?
We stand behind the quality of our parts. This transmission control module comes with a one-year warranty, giving you peace of mind that you’re making a sound investment in your vehicle’s reliability.
