Frequently Asked Questions
Do I need to program this module after I receive it?
No. This is the primary benefit of our service. We pre-program the module to your vehicle’s specific VIN before shipping. It will arrive ready for a plug-and-play installation, with no further programming or dealership visits required.
Where is the TCM located on my 2007-2009 Saturn Aura?
On the Saturn Aura for these model years, the Transmission Control Module is typically located on the front of the left-hand (driver’s side) frame rail in the engine compartment. Always disconnect the battery before beginning removal or installation.
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 underlying issue causing the P0700 (like a faulty solenoid circuit internal to the module), you should always have the specific transmission codes read to confirm the diagnosis. This part is designed to fix the internal electronic failures that trigger these codes.

Is there a core charge for my old part?
No, there is no core charge required for this 2007-2009 Saturn Aura transmission control module. You can keep your old part without the hassle of returning it.
