Is your Saturn Aura shifting erratically, stuck in gear, or flashing transmission warning lights?
Don’t let a faulty Transmission Control Module (TCM) keep you off the road. A failing TCM can cause a cascade of frustrating and potentially dangerous issues, from harsh, unpredictable gear changes to your vehicle entering a performance-limiting “limp mode.” This expertly programmed GM T42 TCM is the direct-fit, plug-and-play solution designed to restore your vehicle’s smooth, reliable performance and get you back to driving with confidence.
Common Symptoms & Your Solution
If you’re experiencing any of the following, a failing TCM is the likely culprit. This module is engineered to be the definitive fix for these common problems:
- Harsh or Erratic Shifting: Abrupt, jerky gear changes or a noticeable delay when the transmission shifts.
- Stuck in Gear / Limp Mode: The vehicle refuses to shift out of a single gear (often 2nd or 3rd) to prevent further damage.
- Warning Lights: The Check Engine Light or a specific transmission warning light is illuminated on your dashboard.
- Diagnostic Trouble Codes (DTCs): Common codes like P0700 (Transmission Control System Malfunction) or various solenoid-related codes (e.g., P0750, P0751) are stored in the computer.
- Poor Performance: A noticeable drop in fuel economy, hesitation, or a feeling that the transmission is slipping.
Installing our Programmed 2007-2009 Saturn Aura TCM resolves these issues by restoring the critical communication link between your engine and transmission, ensuring precise, factory-spec operation.

Frequently Asked Questions
Do I need to take this part to the dealership for programming?
No. This is the primary benefit of our service. We program the module to your vehicle’s specific VIN before shipping it to you. This makes it a true plug-and-play part, saving you the time, cost, and hassle of a dealership visit.
Is this TCM difficult to install?
For the Saturn Aura, the TCM is typically located on the left front frame rail, making it reasonably accessible. With basic hand tools, most DIY mechanics can complete the installation in under an hour. Always remember to disconnect the battery before starting the job.
Will this fix a P0700 trouble code?
A P0700 code is a general fault code indicating that the TCM has detected a problem. While this module often resolves the root cause of a P0700, it’s always best to have the specific secondary codes read by a scanner to confirm the diagnosis. In many cases where the TCM itself has failed, this part is the correct solution.
What happens if I install a module that isn’t programmed to my VIN?
An unprogrammed or incorrectly programmed TCM will not communicate properly with your vehicle’s other electronic systems. This can result in the vehicle not starting, not shifting at all, or exhibiting the same problems you were trying to fix. VIN-specific programming is essential for proper function.
Is a core charge required for this part?
No, there is no core charge for this module. You can keep your old part, avoiding the hassle and expense of shipping it back.
