If the downshift switch is pressed, the gear shift changes to 1st gear
and when the downshift switch is pressed once again, downshifting is
released and returns to 2nd gear automatically.
DHIM C/S
When the auto selector switch is “on” position and the downshift switch pressed,the transmission changes automatically to the next lower gear.
Note: The third to the second gear and the second to the first gear change occur when the engine speed is reduced 200 - 300 rpm from current speed.
DHIM C/S
When the T/M cut off switch(1) is “on” position and the T/M cut off switch(2) has been connected by foot braking (25bar) in the cabin,the transmission will be in neutral position automatically (This function works on 1st, 2nd gear only ).

The AEB has the task to compensate tolerances
(plate clearance and pressure level) which are influencing the fiIling
procedure of the clutches. For each clutch,
the correct filling parameters are determined in one test cycle for
period of the quick-fllling time
