AUTOMATIC TRANSMISSION RANGE SELECTOR POSITIONS
WARNING
Allowing your vehicle to coast in neutral is not recommended. This practice can cause severe damage to transmission.
Use this for backing the vehicle. The vehicle should be completely stopped before shifting from a forward gear to reverse
or from reverse to forward. The reverse warning signal is activated when the range selector is in this position. Reverse
has only one gear.
Use this position when you start the engine. If the engine starts in any other position, the neutral
start switch is malfunctioning. Neutral position is also used during stationary operation of the power
takeoff (if your vehicle is equipped with a PTOL). Use neutral when the vehicle will be left
unattended while the engine is running - apply the parking brake.
nd
Use this for all normal driving conditions. The vehicle will start in 2 gear, and as the accelerator is
depressed, the transmission will upshift to 3rd gear, 4th gear, and 5th gear, automatically. As the
vehicle slows down, the transmission will downshift, within the driving range, to the correct gear,
automatically.
Occasionally, the road, load, or traffic conditions will make it desirable to restrict the automatic
shifting to a lower range. When the conditions improve, return the range selector to the normal
driving position.
Use this position for vehicle speed control and downhill braking. Transmission will start and stay in
2nd gear up to engine governed speed. Both 2nd and 3rd gears are available for engine braking
since a 2-3 shift will occur above engine governed speed. Transmissions prior to S/N 13801 will
provide a 2-3 upshift below engine governed speed.
This is the creeper gear - select this one for off-highway operation. Use the creeper for pulling
through mud or snow. This gear provides the greatest tractive advantage. It is not recommended
that full-power upshifts from 1 to 2-3 be made. Transmissions prior to S/N 19043, when matched
with engines having governed speeds of 3400 rpm or higher, may automatically upshift from 1 to 2-3
before reaching governed speed.
