by an O-ring (34) and a seal (arrow). See Fig. 141
. The contact springs (32) on the PWM converter lockup
solenoid valve (Y3/6y6) engage in a slot in the conductor tracks (33). The force of the contact spring (32)

Operation

operating conditions. Although the selector lever position can be changed the forward gears while driving, the
electronic transmission control (ETC) prevents over-revving of the engine. See Fig. 142

Operation
The selector lever is guided 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. See Fig.
145. 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 (S16/10).
Manual Drive Mode Selection, Function (With Touch Shift)
Transmission with touch shift.
