Operating the Transmission Driving
– 62 –
• Never slam or jerk the shift lever to
complete gear engagement.
• Never coast with the transmission
in Neutral and the clutch disen-
gaged.
• To provide smooth gear engage-
ments while shifting, use proper
coordination between shift lever
and clutch.
Operating Automatic
Transmissions
An automatic transmission makes shift-
ing much easier, of course. But
because your truck pulls a heavy load,
it is important to use it efficiently. For
correct automatic transmission opera-
tion, also see the transmission manu-
facturer's
Operator’s Manual.
• On most automatic transmissions
there is no “PARK” position, so you
will need to apply the parking brake
before leaving the cab. See page
66.
WARNING! Do not leave the
cab without applying the
parking brake. The truck
could roll and cause an
injury accident. Always
apply the parking brake
before you leave the cab.
The MD Automatic Transmission
The MD (electronic) Series of transmis-
sions have four, five, or six forward
speeds, a Neutral position, and one
reverse speed. Pressing the appropri-
ate button selects the desired gear.
Vehicles equipped with the MD trans-
missions have various diagnostic fea-
tures. Refer to the transmission
manufacturer’s
Operator’s Manual
for
