DESCRIPTION AND USE OF OPERATOR CONTROLS AND INDICATORS - CONTINUED

TRANSMISSION CONTROL - CONTINUED

Speed (Gear) Selection - Continued
b.
Speed of machine is selected by rotating end of lever that is located on left side of steering column. Rotate switch
forward or backward to increase or decrease speed of transmission. Transmission will remain in selected speed
until lever is rotated to different speed. Speed of the machine is displayed on front dash.
c.
When transmission downshift switch (see callout
34 on page 0004 00-6) is depressed, it signals
powertrain ECM to downshift transmission by
one speed. If second speed forward or second
speed reverse is selected, transmission will shift
to first speed when switch is depressed. Trans-
mission will remain in first speed until transmis-
sion direction and speed control lever is shifted
to opposite direction or to NEUTRAL.

SERVICE BRAKE CONTROL (PEDALS)
0004 00
1.
Left Service Brake Pedal (1).
a.
Left service brake pedal provides three func-
tions:
(1)
Aggressive automatic downshifting of
transmission
(2)
Neutralization of transmission
(3)
Conventional braking
b.
Left brake pedal is used to initiate automatic
downshifting of transmission at higher ground
speeds than standard automatic downshifting.
c.
When left service brake pedal is depressed to a
certain point, automatic downshifting and neu-
tralization of transmission will occur for all posi-
tions
of
autoshift
switch.
Automatic
downshifting and neutralizing of transmission
saves wear on service brakes, axles, and compo-
nents of powertrain.
d.
Use left brake pedal for most conditions when
427-C0045
adequate traction is available.
2.
Right Service Brake Pedal (2).
a.
Right service brake pedal is used to slow down machine's ground speed when operator does not wish to have
transmission downshift aggressively.
b.
Right service brake pedal is normally used for braking when autoshift transmission control is downshifting ade-
quately.
