Select Shift Transmission (SST) Switches (+ and -)

WARNING: This page is about a different car, the 2005 Lincoln LS. However, it is still accessible from the selected car via links, so may be relevant.

The positions indicated by a (+) or a (-) allow the driver to manually select the appropriate upshift (+) or downshift (-) and gear range.

The SST switches are located within the transmission range selector assembly and are momentary contact switches that send a signal to the powertrain control module (PCM) each time the driver moves the selector lever into the upshift or downshift gear range.

The PCM uses the input signals from the SST+ and the SST- switches, along with other vehicle inputs, to determine which gear should be commanded.
