Restore Smooth Shifting to Your Saturn Vue
If your 2007-2010 Saturn Vue is suffering from erratic shifting, getting stuck in gear, or has an illuminated check engine light, a failing Transmission Control Module (TCM) is the most likely culprit. As a seasoned technician, I’ve seen firsthand how a faulty TCM can cripple a perfectly good vehicle, causing immense frustration for the owner. This T42 Transmission Control Module, part number 24240400, is the definitive solution to restore your vehicle’s drivability and peace of mind. It arrives expertly programmed to your vehicle’s specific VIN, eliminating the need for expensive dealership visits and ensuring a true plug-and-play repair.
Case Study: A Tricky Diagnosis
A customer brought in a 2008 Saturn Vue with a complaint that stumped two other shops: intermittent, violent downshifts, but only after driving for 30+ minutes on the highway. No codes were stored. In the bay, it shifted fine. After a long test drive, I finally experienced the jolt. Back at the shop, I monitored live data and noticed the TCM’s internal temperature readings were spiking just before the harsh shift. The module’s circuit board was failing under heat soak—a classic T42 TCM issue. Replacing it with a pre-programmed unit like this one solved the problem permanently. The original part looked fine, but electronically, it was failing under load.
Is Your Saturn Vue Exhibiting These Telltale Signs?
A failing TCM doesn’t always mean total transmission failure. Often, the signs are electronic and can be mistaken for internal mechanical issues. Before you consider a costly transmission rebuild, check if you’re experiencing any of these common symptoms associated with a bad 2007-2010 Vue Transmission Module:
- âś” Harsh, delayed, or unpredictable gear shifts.
- âś” The vehicle enters “limp mode,” often stuck in 2nd or 3rd gear.
- âś” Check Engine Light or Transmission Warning Light is on.
- âś” Diagnostic Trouble Codes (DTCs) are present, such as the generic P0700 (Transmission Control System Malfunction) or specific solenoid codes like P0751, P0752, P0756, etc.
- âś” A complete loss of communication with the transmission module.
- âś” Poor fuel economy and a feeling of sluggish performance.
A Straightforward Guide to Installation
One of the best features of this module is its ease of installation. Because it comes pre-programmed, you can perform this repair in your own driveway in under 30 minutes with basic hand tools. For the 2007-2010 Saturn Vue, the TCM is conveniently located in the LH (driver’s side) front of the engine compartment.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery to prevent any electrical shorts and to help reset the vehicle’s adaptive memory.
- Locate the Module: On your Saturn Vue, find the TCM in the front left area of the engine bay. It will have several large electrical connectors attached.
- Disconnect and Remove: Carefully unplug the wiring harness connectors. Press the release tabs firmly. Then, unbolt the module from its mounting bracket and remove it from the vehicle.
- Install the New Module: Bolt the new, pre-programmed module into place. Reconnect the wiring harnesses, ensuring they click securely into place.
- Final Steps: Reconnect the battery terminal. While not always necessary, it’s good practice to use a basic OBD2 scan tool to clear any lingering fault codes from the ECU’s memory. Start the vehicle and enjoy restored shifting performance.

What does ‘VIN Programmed’ mean for me?
What does ‘VIN Programmed’ mean for me?
It means we flash the module with your vehicle’s unique Vehicle Identification Number (VIN) and the latest GM software before we ship it. This ensures it communicates perfectly with your vehicle’s other computers right out of the box, saving you a trip to the dealership and hundreds in programming fees.
Do I need a mechanic to install this part?
No, this is a very DIY-friendly repair. With the module being pre-programmed and located in an accessible spot in the engine bay, installation typically requires only basic hand tools and can be completed in under 30 minutes.
Will this fix my P0700 check engine light code?
Yes, in most cases. The P0700 code is a general code indicating the TCM has detected a fault. If the fault is internal to the module itself, replacing it with this unit will resolve the root cause and allow the code to be cleared permanently.
Is a core charge required for my old part?
No, there is no core charge. You are not required to send your old, faulty module back to us, which simplifies the process for you.
