Floor Shift Control, Some Models
WARNING: This page is about a different car, the 2009 Saturn Vue. However, it is still accessible from the selected car via links, so may be relevant.
The floor shift control is located in the center console assembly. It contains the upshift and downshift switches for the electronic range select mode system. The electronic range select mode system is activated when the floor shift control lever is moved to the right into the Low (L) position from the drive position. When the manual position is selected, an upshift is requested by pushing the upshift switch on the floor shift control lever and a downshift is requested by pushing the downshift switch on the floor shift control lever. When an upshift or a downshift is requested, a signal is sent to the TCM which commands the shift solenoids ON or OFF to achieve the appropriate gear.
