WARNING: This page is about a different car, the 2012 Dodge Caliber. However, it is still accessible from the selected car via links, so may be relevant.
The AutoStick function allows the driver to manually change the gear ratio to a locked ratio. The Transmission Control Module (TCM) monitors the AutoStick Upshift and Downshift circuits. If the TCM receives an Upshift and Downshift request simultaneously, or manual mode Upshift/Downshift request while other than in the D-Range, a DTC will set.
