Automatic Gearbox
130
ALLISON 2100 SERIES
General
The automatic gearbox is fully electronically controlled. The automatic gearbox has
5 forward gears and 1 reverse gear.
The automatic gearbox is operated by a selector lever. The selector lever is located
next to the driver's seat.
Shifting gears
The various gears are selected with the selector lever.
Neutral position
No gears are activated in the "N" position. The vehicle is not locked in this position
and can therefore roll.
Use the parking brake to lock the vehicle.
Automatic forward drive
If the "D" position is selected, the vehicle will immediately begin to move (if the
brake system is pressurized and the vehicle is not on the parking brake). It is
therefore advisable to depress the brake pedal before selecting position "D". In this
position the gearbox will automatically shift up and down in all forward gears. In the
"1", "2" and "3" positions the gearbox shifts up to the selected gear. These positions
are used to keep the engine within the proper speed range or to obtain the
maximum engine brake performance.
Reverse
If position "R" is chosen the vehicle will also be immediately set in motion. In this
case, too, first depress the brake pedal and then select "R" position.
