Iveco Daily Euro 4. Manual - part 112
The combined action of the selector lever (2) and the engagement lever (1) cause the rotation and axial movement of the rod
(4) in two subsequent steps to engage the required gear by means of the rods (8-7-6 and 9).
The motion of speed selection/engagement levers occurs through the action of two electric motors (M) managed directly by the
gearbox electronic control unit.

According to the angular position of the selector lever (2),
the slider (3) turns with the rod (4) (which is integral) and the
selector (5) arranges the slider on the 3
rd
/4
th
gear rod (9). At
the same time, the slider (3) moves the rod (10) to prevent
the simultaneous engagement of two gears, to keep the 3
rd
and 4
th
gear engagement rod (9) free and to prevent
movement of the other rods by engaging the grooves in the
rods.

th
gear engagement
According to the movement of the engagement lever (1), the
slider (3) axial moves the rod (4) (which is integral), the
selector (5) (previously arranged) and consequently the
chosen 3
rd
and 4
th
gear engagement rod (9).
Neutral position coincides with the 3

th
gear selection
arrangement.
In this case, the vertical axis of the selector lever (2) is exactly
at 90
° with respect to the horizontal axis of the control
corresponding to no angular variation of the rod (4).
This arrangement is obtained by moving the selector lever (2)
anticlockwise. In this way, the selector (4) is inserted in the
1
st
/2
nd
gear engagement rod (5).
By moving the lever (1), the slider (3) will axially move the
1
st
/2
nd
gear engagement rod (5).
