WARNING: This page is about a different car, the 2009 Jeep Patriot and 2009 Jeep Compass. However, it is still accessible from the selected car via links, so may be relevant.
The transmission control module (TCM) (3) is inside the car, behind the instrument panel to the right of the left kick panel (1) where the clutch pedal would be located. New controllers are shipped with generic software but need to be initialized for the vehicle into which it is installed.
