Component Illustration
Location
The floor shift is located in the center console of the vehicle.
Task
The floor shift is the central control for the driver to influence the shift program of the automatic transmission.
Design
The following components are integrated into the floor shift:
Position indicator
Transmission range recognition switch (S16/10)
Reversing lamp switch (S16/10s1)
Lock for selector lever positions "R" and "P"
Isolating mechanism for "D"-"4" shift
Shift detent
Function
The selector lever is moved and positioned in the shift gate. The selector lever positions "P", "R", "N" and "D" are transmitted mechanically to the
transmission by means of the shift rod. In parallel, all selector lever positions are transmitted to the ETC control module (N15/3) by means of the
transmission range recognition switch (S16/10) in the floor shift. If the selector lever is moved across from "D" to "4", the selector lever is isolated
from the shift rod. Thus there is no longer any mechanical connection with the transmission. The selector lever positions "4", "3", "2" and "1" are then
transmitted electronically to the ETC control module (N15/3) via the transmission range recognition switch.
