Operating the Transmission

Introduction

Your Medium Duty vehicle is equipped with either a man-

ual or automatic transmission with special features and

gearing to meet your particular needs. It is important for

you, the driver, to understand how your particular trans-

mission is operated. To do this, you have two sources of

information: this Operator's Manual and the transmission

manufacturer's Driver/Operator's Instruction Manual.

Because of the variety of different transmissions installed

in Medium Duty vehicles, operating procedures 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 trans-

mission manufacturer's manual that is included with your

vehicle.

NOTE: You will find a shift pattern diagram in the

cab. Check to be sure you know the correct

sequence for your particular transmission.
