Fix Your Saturn Aura’s Shifting Problems for Good
Is your 2007-2009 Saturn Aura suffering from harsh shifts, getting stuck in gear, or throwing transmission codes? Don’t let a faulty Transmission Control Module (TCM) ruin your driving experience. As a technician with over two decades of experience, I’ve seen how a failing TCM can cause a cascade of frustrating, and often misdiagnosed, issues. This OEM-quality T42 Transmission Control Module, part number 24241806, is the definitive, reliable solution. It arrives pre-programmed to your vehicle’s specific VIN, eliminating the need for an expensive trip to the dealership for programming. It’s a true plug-and-play fix designed to get you back on the road with confidence.
Case Study: A Tricky Diagnosis
A customer brought in their 2008 Saturn Aura with a complaint of intermittent, bone-jarring shifts and the transmission light flickering on and off. They’d already replaced a shift solenoid at another shop with no improvement. After hooking up my scan tool, I saw a generic P0700 code but also intermittent communication loss with the TCM. These T42 modules are notorious for developing internal connection failures from heat cycles. Instead of chasing electrical gremlins for hours, we installed one of our VIN-programmed modules. The car immediately shifted perfectly, all codes were cleared, and the customer was thrilled to have their car back, running smoothly without the dealership hassle. This is the fix that works.
Is Your Saturn Aura Showing These Transmission Problems?
A failing TCM can manifest in several ways. If you’re experiencing any of the following, it’s a strong indicator that your module needs replacement:
- âś” Harsh, jerky, or delayed gear shifts.
- âś” Vehicle stuck in “limp mode” (usually 2nd or 3rd gear).
- âś” Check Engine Light or Transmission Warning Light is on.
- âś” Diagnostic Trouble Codes (DTCs) such as P0700, P0750, or other solenoid-related faults.
- âś” Poor acceleration and decreased fuel economy.
- âś” Complete loss of communication with the transmission.
A Straightforward Guide to Installation
You don’t need to be a professional mechanic to install this part. The process is simple and can typically be completed in under 30 minutes with basic hand tools.
- Safety First: Disconnect the negative terminal from your vehicle’s battery to prevent electrical shorts and reset the system.
- Locate the TCM: On the 2007-2009 Saturn Aura, the TCM is located on the front portion of the left-hand frame rail.
- Disconnect and Remove: Carefully unplug the electrical connectors from the old module. Then, unbolt the module from its mounting bracket.
- Install the New Module: Bolt the new, VIN-programmed TCM into place and securely reconnect the electrical connectors.
- Reconnect and Verify: Reconnect the negative battery terminal. Start the vehicle to ensure it shifts smoothly. It’s recommended to use a basic scan tool to clear any stored fault codes.

Frequently Asked Questions
What is VIN programming and why is it important?
VIN programming loads your vehicle’s unique identification number and specific operational software onto the TCM. This ensures the module communicates perfectly with your car’s engine computer and other systems for optimal shift strategy and performance. Our service saves you a mandatory, and costly, programming session at a dealership.
Will this 2007-2009 Saturn Aura TCM fix a P0700 trouble code?
Yes. The P0700 code is a general fault code indicating the TCM has detected a problem. Often, the root cause is the TCM itself. Replacing a failing module with this pre-programmed unit will typically resolve the issue and allow the code to be cleared.
Is any special tool required for this installation?
No special tools are needed. Basic hand tools, like a socket set and ratchet, are all that is required to unbolt the old module and install the new one. A code reader is helpful for clearing old codes but not always necessary.
Do I need to send my old part back (core charge)?
No, there is no core charge for this part. You can keep your old module or dispose of it, making the process faster and more convenient for you.
