OPERATING AUTOMATIC TRANSMISSIONS
Clutch Adjustment
Inspect manual clutches according to the manufacturer's
recommendations. Regular maintenance should be followed
to maintain correct clutch adjustment. Have your
dealer's Service Department perform any adjustment necessary.
Tips
• Always use the clutch when making upshifts or downshifts.
• Always select a starting gear that will provide sufficient
gear reduction for the load and terrain.
• Never downshift when the vehicle is moving too fast.
• Never slam or jerk the shift lever to complete gear
engagement.
• Never coast with the transmission in Neutral and the
clutch disengaged.
STARTING AND OPERATING THE VEHICLE
• To provide smooth gear engagements while shifting,
use proper coordination between shift lever and
clutch.
Operating Automatic Transmissions
An automatic transmission makes shifting much easier,
however it is important to understand how to operate the
transmission efficiently. Please read the transmission
manufacturer’s operation manual supplied with your vehicle.
There may not be a “park” position with your automatic
transmission. Always be sure you apply the parking brake
before leaving the cab.
WARNING! Do not leave the cab of your vehicle
without applying the parking brake. The
truck could roll and cause an accident resulting
in death or personal injury. Always apply
the parking brake before you leave the cab.
