If your 2007-2010 Saturn Vue is suffering from erratic shifting, getting stuck in gear, or throwing transmission codes, you’ve come to the right place. As a technician with over two decades of experience, I’ve seen countless drivers worry they need a costly transmission rebuild when the real culprit is a failed Transmission Control Module (TCM). This module is the electronic brain of your automatic transmission, and when it fails, it can cause a host of frustrating and concerning problems. This T42 TCM, part number 24238856, is the reliable, cost-effective solution to restore your vehicle’s performance and peace of mind.
We take the guesswork and extra expense out of the repair by pre-programming this module to your vehicle’s specific VIN. This means it arrives ready for a true plug-and-play installation, with no need for an expensive trip to the dealership for programming. It’s designed to directly address the root cause of many common transmission issues, ensuring smooth gear changes, proper torque converter lockup, and accurate communication with your vehicle’s main computer.
A Technician’s Notebook
A customer recently brought in their 2008 Saturn Vue with a classic complaint: intermittent ‘limp mode.’ It would drive fine for days, then suddenly refuse to shift out of 3rd gear, with the check engine light on. They had already replaced two shift solenoids at another shop with no success. After a quick scan, I saw the tell-tale P0700 (Transmission Control System Malfunction) code. Instead of tearing into the transmission, I checked the TCM connections. In my experience, these T42 modules are prone to internal electronic failure from heat and vibration over time. We installed one of our VIN-programmed units, and the problem was solved instantly. The customer saved over a thousand dollars compared to the transmission overhaul they were quoted elsewhere. It’s a perfect example of how diagnosing the electronics first can save a lot of time and money.
Is Your Vue Showing These Telltale Signs?
A failing TCM can manifest in several ways. If you’re experiencing any of the following, this module is likely the solution you need for your 2007-2010 Vue Transmission Module.
- ✔ Harsh, jerky, or delayed gear shifts.
- ✔ Vehicle is stuck in one gear (often called ‘limp mode’).
- ✔ Check Engine Light or Transmission Warning Light is illuminated.
- ✔ Diagnostic Trouble Codes (DTCs) such as P0700, P0750, or other solenoid-related faults are present.
- ✔ Complete loss of shifting capability or failure to engage a gear.
- ✔ A noticeable decrease in fuel economy.
A Straightforward Guide to Installation
One of the best features of this part is its simple installation, making it a great job for a DIY enthusiast or a quick swap for a professional mechanic. For most Saturn Vue models, the TCM is located in the front of the engine compartment.
- Safety First: Before you begin, disconnect the negative terminal from your vehicle’s battery to prevent any electrical shorts and to help reset the system.
- Locate the Old Module: On the 2007-2010 Saturn Vue, the TCM is typically found in the LH (driver’s side) front of the engine compartment. It’s a silver box with electrical connectors.
- Swap the Module: Carefully unplug the wiring harnesses from the old TCM. Then, unbolt the module from its mounting bracket. Secure the new module in place, and firmly reconnect the wiring harnesses. Ensure they click into place.
- Final Steps: Reconnect the battery terminal. Start the vehicle and let it run for a few minutes. While our programming resolves most issues, it’s good practice to use a basic OBD2 scanner to clear any stored fault codes from the vehicle’s memory.
