... is a so-called 3/4 way valve with
3 connections and 4 switch positions.
It is controlled by the control unit for
additional shift stage J554 with U
Batt
pulse-
width-modulation.
Depending on the pulse width, the valve for
the hydraulic regulator N331 moves to
positions 1 - 4 (see shift positions from
Page 48 on).
Connections:
P = pressure connection (input)
T = stands for tank, meaning the return to

Travel sensor for hydraulic regulator G302
The positions and movements of the selector
rod and thus the selector sleeve are
determined with the aid of the G302.
The control unit requires the position for the
plausibility check and monitoring of the
shifting procedure.
Further details can be found under Hydraulic
regulator travel sensor G302, Page 56.
