Operation
When the selector lever is moved across from "D" to "4", the shift shaft (66) is moved axially to the left and the
straight pin (68c) is thus pushed out of the intermediate lever (68a). See Fig. 24
.
At the same time the lock lever (68b) is pushed into the recess in the intermediate lever (68a). The locking lever
(68b) locks the intermediate lever (68a). This fixes the shift rod in selector lever position "D". The straight pin
(68d) fixes the lock lever (68b) on the shift shaft (66) and projects into a recess in the guide plate. This recess
allows the shift shaft (66) to be moved in the transverse direction only when the selector lever is in position "D".

Transmission Range Recognition Switch, Task
To convey the respective position of the selector lever to the ETC control module (N15/3).
Transmission Range Recognition Switch, Design
The gear identification switch (S16/10) consists of the shift range contacts for all gears, the reverse lamp
switch (S16/10s1) as well as 10 LEDs (70) for the background illumination and the individual position
display.
Transmission Range Recognition Switch, Function
The selector lever positions are transferred to the gear identification switch (S16/10) by a plug pin, which
is connected to the shift shaft, and processed into a position signal. This signal is passed to the ETC
control module (N15/3).
