now sure of your intentions:
not sure of the build for this vehicle; automatic transmissions can have their own module... tcm or be control by the powertrain module.. pcm
-if you have a transmission complaint you can check with the dealer to see if a tcm update is available. they would have to connect to the car with a dealer scan tool.
-tuners can adjust tcm programming but it would void powertrain warranty.

These are not cheap.
I did a lot of searching around, dealers are getting up to $680 for a new one.
I'm in an auto related business and even the jobber price was $560.
I've seen them new for as low as $499 online.
However, there's rebuilder in GA that sells them for $199, so this is what I went with UpFix.com
Instructions included in the box show a diagram recommending that you wire-tie it to the brake lines so it no longer absorbs heat from the transmission. The heat is what kills them. They also include a small flat-rate box and address label for the core return.
Shipping was super fast too.
