Theory Of Operation
WARNING: This page is about a different variant/trim than selected.
The AutoStick® switch contains two hall effect switches connected to ground. The Powertrain Control Module (PCM) has two separate inputs, upshift and downshift. When the PCM detects an input from the switch, upshift or downshift, it will shift the transmission to the desired gear. If the PCM detects both inputs at the same time, the DTC will set.
