Case 580SR, Service Manual

Page: 73 / 1068

SECTION 21 - TRANSMISSION 7
Transmission
The transmission is fully synchronised providing four
forward and four reverse speeds allowing gear ratio
changes on the move. A torque converter is used to
connect the engine to the transmission and the col-
umn mounted powershuttle lever (4) enables shifts
between forward and reverse travel without disen-
gaging gear ratios.
A device for “transmission disconnect” is activated
by pushing button (2), placed on the gearshift lever
(1) or by pushing button (5), placed on the loader
control lever (3).
S WARNING
Always apply the parking brake whenever the ma-
chine is parked as the machine is free to roll even
though the transmission gearshift lever and power
reversing lever may be “In Gear” and the engine is
turned OFF.
Gearshift lever
The single gearshift lever (1) is used to select any
one of the four gear ratios. The transmission discon-
nect button (2) is depressed and held as the lever is
shifted from one gear to another and then released
to re-connect transmission drive.
