Is your 2007-2010 Saturn Vue suffering from jarring shifts, getting stuck in gear, or an illuminated check engine light? You’re likely dealing with a failed Transmission Control Module (TCM). As a technician with over two decades of experience, I’ve seen how a faulty TCM can sideline a perfectly good vehicle. This T42 Transmission Control Module, part number 24240449, is the definitive solution, arriving pre-programmed to your vehicle’s specific VIN for a true plug-and-play repair.
This module is the brain of your automatic transmission, controlling everything from shift points to torque converter clutch engagement. When it fails, communication between the engine and transmission breaks down, leading to the frustrating and sometimes unsafe driving conditions you’re experiencing. Our process eliminates the need for expensive dealership visits for programming—we handle it all before it ships, ensuring it works correctly right out of the box.
Case Study: A Tricky Diagnosis
A customer brought in a 2008 Chevy HHR with classic symptoms: harsh 1-2 shift and a P0752 (Shift Solenoid ‘A’ Stuck On) code. The previous shop had already replaced the solenoid twice with no success. After a quick data stream analysis, I noticed the TCM was commanding the solenoid on, but the pressure control readings were erratic. This pointed directly to an internal TCM fault. We installed one of our VIN-programmed T42 modules, and the problem was solved in under an hour. It’s a common scenario where the TCM itself is the root cause, not the components it controls.
Is Your Saturn Vue Showing These Telltale Signs?
- ✔️ Harsh, slamming, or delayed gear shifts.
- ✔️ Vehicle is stuck in “limp mode” (usually 2nd or 3rd gear).
- ✔️ Check Engine Light or Transmission Warning Light is on.
- ✔️ Diagnostic Trouble Codes (DTCs) like P0700, P0750-P0758, or other solenoid-related faults are present.
- ✔️ The transmission refuses to upshift or downshift correctly.
- ✔️ A noticeable decrease in fuel economy.
A Straightforward Guide to Your TCM Installation
This is a job most DIYers can handle in their driveway. For the 2007-2010 Saturn Vue, the TCM is typically located in the left front of the engine compartment. Always consult a service manual for your specific model’s exact location.
- Safety First: Disconnect the negative terminal from your vehicle’s battery to prevent electrical shorts and reset the system.
- Locate the Module: Find the old TCM. It’s a metal box with large electrical connectors. On the Vue, it’s often near the strut tower or under the air cleaner box.
- 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. Start the vehicle and let it idle for a few minutes. If you have a basic scan tool, it’s good practice to clear any stored codes. No further programming is required.

Frequently Asked Questions
Do I need to get this module programmed by a dealer?
No. We pre-program the module to your vehicle’s VIN before it ships. It is a plug-and-play installation with no additional programming needed.
Is there a core charge for my old part?
No, there is no core charge. You can keep your old module, which saves you the time and expense of shipping it back.
What tools do I need for installation?
Basic hand tools are all that’s required, typically a socket set to remove the mounting bolts and a flathead screwdriver to help release the connector clips. The entire process usually takes less than 30 minutes.
Will this fix a P0700 trouble code?
A P0700 code is a general transmission fault request, meaning the TCM has detected a problem and asked the main computer (PCM) to turn on the check engine light. While this module often resolves the underlying issue causing the P0700, you should scan for more specific codes (like P07xx) to confirm the diagnosis.
What if my part number is slightly different?
This module replaces many interchangeable part numbers, including 24252114, 24234503, and others. As long as your vehicle is listed in our compatibility chart, this module will function correctly as a replacement.
