Stop Guessing and Start Driving: The Definitive Fix for Your Saturn’s Transmission Woes
Is your Saturn Vue shifting erratically, getting stuck in gear, or throwing transmission codes? As a technician with over two decades of experience under the hood, I’ve seen these symptoms countless times. A faulty Transmission Control Module (TCM) is one of the most common culprits on these GM platforms, turning a reliable daily driver into a source of constant frustration. This isn’t just an inconvenience; it’s a safety issue. You need a solution that works right out of the box, and this is it. This T42 TCM, part number 24241806, is your direct-fit, pre-programmed answer to restore the smooth, predictable performance your vehicle was designed for.
From the Diagnostic Bay
I remember a 2009 Saturn Vue that came into the shop stuck in ‘limp mode’—the transmission wouldn’t shift past 3rd gear. The owner had already replaced a shift solenoid based on a generic code reading, but the problem persisted. A quick scan with my professional tool showed a P0700 (Transmission Control System Malfunction) and intermittent communication errors with the TCM. Instead of a costly and time-consuming internal transmission repair, we identified the root cause: a failing TCM. We installed one of our VIN-programmed modules, and in less than an hour, the car was shifting perfectly through all gears. This part saved the customer hundreds, if not thousands, in unnecessary repairs and dealership fees.
Is Your Saturn Vue Showing These Telltale Signs?
A failing TCM doesn’t always mean total transmission failure. Often, the signs are subtle at first. If you’re experiencing any of the following, it’s a strong indicator that your TCM is the problem.
- ✔ Harsh, slamming shifts or sudden, jerky gear changes.
- ✔ The vehicle is stuck in a single gear (often called limp mode).
- ✔ Check Engine Light or Transmission Warning Light is illuminated on the dash.
- ✔ Diagnostic Trouble Codes (DTCs) are present, such as P0700, P0750, or other solenoid-related faults.
- ✔ Delayed engagement when shifting from Park to Drive or Reverse.
- ✔ A noticeable decrease in fuel economy due to inefficient shifting.

- Safety First: Always disconnect the negative terminal from your vehicle’s battery before starting any electronic repair.
- Locate the Module: On your Saturn Vue, the TCM is found in the engine compartment, usually on the driver’s side (LH) front area, near the strut tower or under the air cleaner box.
- Disconnect and Remove: Carefully unplug the electrical connectors. Use a socket wrench to remove the bolts or nuts holding the old module in place.
- Install the New TCM: Mount the new, pre-programmed module in the same location and secure it with the original hardware. Reconnect the electrical connectors, ensuring they click securely into place.

Frequently Asked Questions
What does VIN programming mean for me?
It means this module is ready for installation the moment you receive it. We flash it with your vehicle’s specific VIN and the latest GM software, so it communicates perfectly with your engine and other systems without requiring any additional, costly programming from a dealer or specialized shop.
Do I need to take my car to a dealer after installation?
No. Because the module is pre-programmed to your VIN, you can skip the dealership entirely. Installation is a straightforward swap, saving you time and money.
Where is this TCM located on my 2008 Saturn Vue?
On the 2007-2010 Saturn Vue, you will typically find the TCM in the engine bay, located on the driver’s side (LH) front of the engine compartment. It is often near the strut tower or under the air cleaner assembly.
Will this fix a P0700 trouble code?
A P0700 code is a general fault code indicating the TCM has detected a problem. While this module often resolves the root cause (the faulty TCM itself), it’s always wise to ensure there aren’t other issues. However, in many cases, replacing a failing TCM will clear the P0700 and related specific codes.
Is there a core charge for my old part?
No, there is absolutely no core charge. You can keep your old module or dispose of it at your convenience without any extra fees or hassle.
