PB1318 3/01 Model 330
OPERATING THE TRANSMISSION
Introduction
Your Model 330 is equipped with either a manual or auto-
matic transmission with special features and gearing to meet
your particular needs. It is important for you, the driver, to
understand how your particular transmission is operated. To
do this, you have two sources of information: this
Operator’s
Manual
and the transmission manufacturer’s
Driver/Opera-
tor’s Instruction Manual
. Because of the variety of different
transmissions installed in Model 330 vehicles, operating pro-
cedures for your particular transmission are not included in
this manual; therefore, you should read and understand both
manuals. Read the general guidelines and instructions that
follow and read the specific instructions contained in the
transmission manufacturer’s
Driver/Operator’s Instruction
Manual
.
NOTE: You will find a shift pattern diagram in the
cab. Check to be sure you know the correct
sequence for your particular transmission.

6, 9, 10, and 11–Speed Manual
The 6–speed synchronized manual transmission has 6 for-
ward speeds and 1 reverse. The 9–speed transmission has 9
forward and 2 reverse speeds, consisting of a 5–speed low
range section and a 4–speed high range section.
For specific instructions on operating one of the optional 10-
or 11-speed transmissions, consult the transmission manu-
facturer’s Driver/Operator Instruction Manual.
Transmission Warm–Up
In cold weather [below 32°F (0°C)], you may find shifting
sluggish when you first start up. Transmission warm-up is
especially important at this time, but it is always a good idea
to warm your transmission oil before starting out on the road.
