Automatic And Automated Transmissions - Peterbilt 348 2017 Operator's Manual

OPERATING THE TRANSMISSION
Automatic and Automated
Transmissions
An automatic or automated
transmission makes shifting much
easier. It remains important to
completely understand how to operate
the transmission to optimize its
efficiency. Please read the manual
for your automatic or automated
transmission included with your
vehicle.

For automated transmissions, there is
no "park" position. So you will need to
apply the parking brake before leaving
the cab.

Hill Hold
The hill hold feature is available as
an option with certain automated
transmissions. This feature holds the
vehicle while on a hill to allow the
operator to release the service brakes
and press the accelerator. This feature
will hold the vehicle if the vehicle is
attempting to go up a hill from a stop in
either drive or reverse.
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 per-
sonal injury. Always apply the park-
ing brake before you leave the cab.

WARNING!
If your vehicle has an automated
transmission, be aware that it can
roll backwards when stopped on a
hill or grade, or when starting from
a stop on a hill or grade. Failure to
comply may result in death, personal
injury, equipment or property dam-
age. Observe the following guide-
lines:
• When stopped on a hill or grade,
press the brake pedal.
• When starting from a stop on a
hill or grade, quickly remove your
foot from the brake pedal and
firmly press on the accelerator
pedal.
