From the Technician’s Bench: The T42 TCM is the brain of your 4-speed automatic transmission. We’ve seen countless GM vehicles where owners have replaced solenoids and sensors, only to find the root cause was the module itself. The most critical step is the VIN programming. An unprogrammed module simply won’t communicate correctly with your vehicle’s other computers, leading to the same old problems. Our process ensures the module is a perfect digital match for your Aura from the moment you plug it in, saving you hours of diagnostics and frustration. This is the correct way to fix it once and for all.

Frequently Asked Questions
Do I need to take this part to a dealer for programming?
No. This is the primary benefit of our service. The module arrives at your door pre-programmed to your vehicle’s VIN and is ready for immediate installation. You will not need any additional programming from a dealership or mechanic.
Where is the TCM located on my 2007-2009 Saturn Aura?
On the Saturn Aura models from 2007 to 2009, the Transmission Control Module is typically located on the front portion of the driver’s side (LH) frame rail in the engine compartment.
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 of a P0700, it’s essential to ensure any other related codes (like solenoid faults) are also addressed. In many cases, a failing TCM is the primary culprit.
Is any special tool required for installation?
No special tools are required. Basic hand tools like a socket set and ratchet are typically all that’s needed to access and replace the module. The most important step is to disconnect the vehicle’s battery before you begin.
What happens if I don’t disconnect the battery before installing?
Disconnecting the battery is a critical safety step that prevents electrical shorts and potential damage to the new module or other vehicle electronics. It also helps the vehicle’s computer systems reset and properly recognize the new TCM upon reconnection.
Is this the correct 2007-2009 Saturn Aura transmission control module for my car?
Yes, this T42 module is the correct fitment for 2007, 2008, and 2009 Saturn Aura models equipped with a 4-speed automatic transmission. It is programmed specifically to your VIN to ensure perfect compatibility.
