Restore Smooth Shifting to Your Saturn Vue
If you’re dealing with the headaches of a faulty transmission—like harsh shifting, getting stuck in gear, or a persistent check engine light—you’ve come to the right place. As a technician with over 20 years of experience diagnosing these exact issues, I know how frustrating a failing Transmission Control Module (TCM) can be. This isn’t just a part; it’s the solution to getting your vehicle’s drivability and reliability back. This T42 TCM, corresponding to part number 24240449, is the brain of your automatic transmission, and we’ve made replacing it easier than ever.
We take the guesswork and extra expense out of the repair by pre-programming this module to your vehicle’s specific VIN. This means no costly trips to the dealership for programming. It arrives at your door ready for a true plug-and-play installation, restoring the precise shift logic and communication your Saturn Vue was designed with. This is the definitive fix for many common transmission-related DTCs and performance problems.
A Technician’s Notebook
I recently had a 2009 Saturn Vue 2.4L come into the shop. The owner was frustrated because it would intermittently refuse to shift out of 2nd gear, and he’d already replaced a shift solenoid with no luck. The scanner showed a general P0700 code. Instead of just throwing more parts at it, we looked at live data. We saw erratic signal outputs from the TCM, even when the solenoids were commanded on. This is a classic sign of internal TCM failure. We installed one of our VIN-programmed modules, and the problem was solved instantly. The vehicle shifted perfectly on the test drive, proving that a correct diagnosis and a quality part save time and money.
Is Your Saturn Vue Showing These Symptoms?
A failing TCM can manifest in several ways. If you’re experiencing any of the following, a faulty module is a likely culprit:
- ✔ Harsh, erratic, or delayed gear shifts.
- ✔ Vehicle stuck in a single gear (limp mode).
- ✔ Check Engine Light or Transmission Warning Light is on.
- ✔ Diagnostic Trouble Codes (DTCs) such as P0700, P0750, or other solenoid-related faults.
- ✔ Complete loss of communication with the transmission module.
- ✔ Decreased fuel economy and a feeling of sluggish performance.
A Straightforward Guide to Installation
For the DIYer or professional mechanic, installing this 2007-2010 Vue TCM is a simple process that typically takes less than 30 minutes. The module is located in the engine compartment for easy access.
- Safety First: Disconnect the negative terminal from your vehicle’s battery to prevent any electrical shorts and to help reset the system.
- Locate the Module: On the 2007-2010 Saturn Vue, the TCM is typically found in the LH (driver’s side) front of the engine compartment.
- Disconnect and Remove: Carefully unplug the electrical connectors. Then, unbolt the old module from its mounting bracket.
- Install the New Module: Bolt the new, pre-programmed TCM into place and securely reconnect the electrical harnesses. Ensure they click into place.
- Final Steps: Reconnect the battery terminal. While the module is plug-and-play, it’s good practice to use a scan tool to clear any stored fault codes from the vehicle’s memory.

Frequently Asked Questions
Do I need to get this module programmed by a dealer?
No. This is the biggest benefit we offer. We program the module to your vehicle’s VIN before shipping, so it’s ready for immediate installation right out of the box. This saves you time and the high cost of dealership programming.
Where is the TCM located on a 2008 Saturn Vue?
On most 2007-2010 Saturn Vue models, you will find the Transmission Control Module in the front left (driver’s side) of the engine compartment.
Will this fix a P0700 trouble code?
A P0700 code is a general fault request from the TCM to the main engine computer (ECM) to turn on the check engine light. While this module often resolves the underlying issue causing the P0700, you should scan for more specific transmission codes (e.g., P07xx) to confirm the diagnosis. A failing TCM is a very common cause.
Is there a core charge for my old part?
No, we do not require a core charge. You can keep your old part, which simplifies the process for you.
What kind of warranty is included?
This module is backed by our one-year warranty, giving you peace of mind and confidence in your repair.
