Is Your Saturn Vue Experiencing Transmission Problems?
If you’re dealing with erratic shifting, a check engine light that won’t go away, or your 2007-2010 Saturn Vue suddenly going into limp mode, a faulty Transmission Control Module (TCM) is the most likely culprit. The TCM is the electronic brain of your automatic transmission, responsible for orchestrating smooth gear changes, managing torque converter lockup, and ensuring overall drivetrain efficiency. When it fails, it can cause a cascade of frustrating and potentially damaging issues, turning your daily drive into a source of stress.
This OEM-quality T42 Transmission Control Module, service number 24239224, is the definitive solution to restore your vehicle’s performance. We take the guesswork and extra expense out of the repair by pre-programming the module to your vehicle’s specific Vehicle Identification Number (VIN). This means it arrives at your door ready for a true plug-and-play installation, with no need for a costly trip to the dealership for programming.
From the Diagnostic Bay
We had a 2008 Saturn Vue come into the shop with classic symptoms: harsh 1-2 shifts and occasionally getting stuck in 3rd gear. The owner had already replaced two shift solenoids with no luck. A quick scan showed a P0700 (Transmission Control System Malfunction) code, but no specific solenoid faults. Instead of throwing more parts at it, we inspected the TCM wiring and found no issues. We knew from experience that these T42 modules can develop internal faults that don’t always throw a specific code. We installed one of our VIN-programmed modules, cleared the codes, and the vehicle shifted perfectly on the test drive. The customer was thrilled to have a simple, definitive fix after weeks of uncertainty.
Common Symptoms of a Failing Saturn Vue TCM
A failing TCM can manifest in various ways. If you’re experiencing any of the following, it’s a strong indication that your module needs replacement:
- âś” Harsh or Delayed Shifting: Gears slam into place, hesitate during engagement, or feel like they’re slipping.
- âś” Stuck in Gear / Limp Mode: The transmission defaults to a single gear (usually 2nd or 3rd) to prevent further damage, severely limiting vehicle speed.
- âś” Warning Lights: The Check Engine Light or a specific transmission warning light is illuminated on your dashboard.
- âś” Diagnostic Trouble Codes (DTCs): You may find codes such as P0700, P0750, P0753, P0758, or other solenoid-related faults when using a scan tool.
- âś” Poor Fuel Economy: Inefficient shifting and torque converter operation lead to a noticeable decrease in MPG.
- âś” No Communication: In severe cases, a scan tool may be unable to communicate with the TCM at all, indicating a complete module failure.
The Plug-and-Play Advantage: VIN Programming Included
Why choose our module? The single most important feature is our complimentary VIN programming service. Modern vehicles require the TCM to be matched to the specific vehicle it’s installed in. Skipping this step will result in the vehicle not starting or the transmission not functioning correctly. Our process eliminates this hurdle:
- Provide Your VIN: Simply enter your vehicle’s VIN when placing your order.
- We Handle the Rest: Our technicians flash the module with the latest GM software updates specific to your vehicle.
- Install with Confidence: The module arrives ready to be installed. Just disconnect the battery, swap the part, and reconnect. The system will recognize the new module, and you’ll be back on the road.
This module is a direct replacement for a wide range of GM part numbers, including 24252114, 24234503, 24230461, 24239224, and many more, ensuring broad compatibility across numerous models like the Chevrolet Silverado, GMC Sierra, Buick LaCrosse, and Pontiac G6.
Frequently Asked Questions
What is VIN programming and why is it necessary?
VIN programming is the process of loading your vehicle’s specific software and calibration files onto the Transmission Control Module. This ensures the TCM communicates correctly with the engine computer and other vehicle systems for optimal shift points, fuel economy, and performance. Without it, the vehicle will not operate correctly.
Is this a difficult part to install myself?
For most DIY mechanics, this is a straightforward installation. The TCM is typically located in the engine bay (e.g., on the LH strut tower, next to the battery, or under the air cleaner box). The process involves disconnecting the battery, unplugging the electrical connectors, unbolting the old module, and installing the new one. It usually takes less than 30 minutes.
Will I need any special tools for this job?
You will only need basic hand tools like a socket set to remove the mounting bolts. A code scanner is recommended to clear any stored diagnostic trouble codes from the vehicle’s memory after the installation is complete, but it is not always required.
Do I need to return my old TCM?
No, there is no core charge for this part. You can keep your old module without any extra fees or hassle, making the repair process simpler and more convenient for you.
How do I know this will fit my vehicle?
This T42 TCM fits a wide range of 2006-2014 GM vehicles. Please use the vehicle fitment tool on our website or match your original part number to the list of compatible numbers on this page. Providing your VIN at checkout allows us to double-check compatibility and program it correctly for your specific make and model.
