Synchronised Shuttle Shift Transmission
The
fully synchronised
shuule
shift transmission
is
of
an advanced
design
having
eight
forward and
reverse gear ratios
(8

Synchronised shuttle shift transmission is
oper-
ated by means
of
the clutch pedal, the
main
gear
shift lever, the range
lever
and the shuttle shift
lever
(sec
Figure

The
main
gear
shift lever, the
range lever and the shuttle shift
lever
are
identi-
fied
by
orange coloured knobs.
The
main
gear
shift
lever
is used to select any
one
of
four
gear
ratios.
The
range lever is used to select
the high
or
low rnngc, which
has
the effect
of
dou-
bling the number
gear
ratios to eight, both
in
for-
ward and reverse.
The
shift pattern is clearly
marked
on
a decal affixed to the right-hand fender
and is also shown in Figure 9.
