If your 2007-2010 Saturn Vue is suffering from harsh shifting, getting stuck in gear, or throwing transmission codes, you’ve likely pinpointed the culprit: a failing Transmission Control Module (TCM). As a technician with over two decades of experience, I’ve seen countless GM vehicles sidelined by this exact issue. The T42 TCM is the brain of your automatic transmission, and when it fails, it creates frustrating and unpredictable driving behavior. This isn’t just an annoyance; it’s a safety concern.
We offer a dependable and straightforward solution. This OEM-quality T42 TCM, part number 24239926, is the definitive fix for your vehicle’s transmission woes. The most significant advantage we provide is our expert VIN programming service. When you order, we flash the module with your vehicle’s specific VIN and the latest GM software updates. This means it arrives at your door ready for a true plug-and-play installation, completely bypassing the need for an expensive trip to the dealership for programming. This is the same process we use in our own repair facility to guarantee a successful repair the first time.
Case Study: A Tricky Diagnosis
A customer brought in a 2009 Saturn Vue 2.4L that was intermittently going into ‘limp mode’ (stuck in 3rd gear) and showing a P0752 (Shift Solenoid ‘A’ Stuck On) code. They had already replaced the solenoid pack at another shop, but the problem persisted. After a quick data stream analysis, I noticed the command signals from the TCM were erratic. The issue wasn’t the solenoid; it was the TCM’s internal driver circuit failing under heat. We installed one of our VIN-programmed T42 modules, and the vehicle has been shifting perfectly ever since. This is a classic example of how a faulty module can mimic a mechanical failure, making a correct diagnosis crucial.
Is Your Saturn Vue Showing These Telltale Signs?
A failing TCM doesn’t always mean a complete transmission breakdown. Watch for these early warning signs. Addressing them with a new 2007-2010 VUE Transmission Module can prevent more severe damage.
- ✔ Abrupt, harsh, or delayed gear shifts.
- ✔ The vehicle is stuck in a single gear, often referred to as “limp mode.”
- ✔ Check Engine Light or Transmission Warning Light is illuminated.
- ✔ Diagnostic Trouble Codes (DTCs) are present, such as the general P0700 or specific solenoid codes (e.g., P0750, P0752).
- ✔ Inability to upshift or downshift, leading to poor acceleration and fuel economy.
- ✔ A complete loss of communication with the transmission module.
Your 30-Minute Path to a Smooth Ride
One of the best parts of this solution is how accessible the repair is for a DIY enthusiast. You don’t need a vehicle lift or specialized transmission tools. The module is located in the engine bay, making for a quick swap.
- Safety First: Disconnect the negative terminal from your vehicle’s battery to prevent any electrical shorts and to help reset the system.
- Locate the TCM: On the Saturn Vue, the TCM is typically found in the LH front of the engine compartment. It’s a silver box with electrical connectors.
- Disconnect and Remove: Carefully unplug the wiring harnesses. They have locking tabs that need to be released. Then, unbolt the module from its mounting bracket.
- Install the New Module: Bolt the new, pre-programmed TCM into place and securely reconnect the wiring harnesses. You should hear a ‘click’ as they lock.
- Final Steps: Reconnect the battery terminal. While the module is plug-and-play, it’s always best practice to use a basic OBD2 scan tool to clear any stored fault codes from the vehicle’s memory. Start the vehicle and enjoy restored shifting performance.

Frequently Asked Questions
Do I need to program this module?
No. This is the core benefit of our service. We pre-program the module to your vehicle’s VIN before shipping, so it’s ready for installation right out of the box. You will not need to visit a dealer.
What information do you need from me?
We require your vehicle’s 17-digit Vehicle Identification Number (VIN) to ensure the module is programmed with the correct software for your specific car and its options.
Is this a difficult part to install myself?
Not at all. For most DIYers with basic hand tools, this is a very straightforward job that takes less than 30 minutes. The module is easily accessible in the engine bay.
Will this fix a P0700 trouble code?
Yes, in most cases. A P0700 code is a general fault code indicating the TCM has detected a problem. If the TCM itself is the source of the fault, replacing it with our programmed module will resolve the issue and allow the code to be cleared.
Is there a core charge for my old part?
No, we do not require you to send back your old module. There is no core charge, saving you time and return shipping costs.
What is the warranty on this part?
This transmission control module comes with a one-year replacement warranty, giving you confidence and peace of mind in your repair.
