DAILY
OPERATION
D Check the transmission fluid.
D Visually check the gear shift linkage and transmission.
P Start the engine in neutral. Allow a few minutes at idle
for the fluid to warm.
NOTE:
Too
low
an
idle
speed will produce a chattering
noise from
the
transmission gear and damper
plate.
In
such
cases
the
idle
speed slwuld
be
increased.
D Shift into gear.
A
CAUTION:
Shifting
gears
above
1000
rpm
can
cause
damage
to
the
engine
damper
plate.
Pulling
the
throttle
back
to
idle
when
shifting
gears
will
save
wear
on
the
transmission
and
the
damper
plate.
INSPECTION
D Visually check for oil leaks at the hydraulic connections.
Check for wear on the hydraulic lines and replace
if
worn.
D Lubricate the detent ball and shift cable attachments.
D Inspect the shift linkage.
D Inspect the transmission bolts; retorque
if
necessary.
A
CAUTION:
Clutch
failure
will
occur
if
the
transmission
shift
lever
does
not
fully
engage
the
detent
ball
positions.
CHANGING
THE
TRANSMISSION
FLUID
After the initial
50
hour change, the transmission fluid should
be changed
at
every 300 operating hours thereafter or at win-
ter haul-out. However, the fluid must be changed whenever it
becomes contaminated, changes color, or smells rancid.
D Remove the oil filler cap and dipstick.
D Remove the oil cooler return line and allow the oil to
drain into a container.
D Reconnect the oil cooler return line.
D Use a suction pump to remove the transmission oil
through the filler cap/dipstick hole.
D Clean off the transmission and properly dispose
of
the
used fluid.
Refill the transmission with
DEXTRON
III
ATF.
The
quantity will vary depending on the transmission model
and the installation angle. Pill through the dipstick hole.
Check the dipstick for the proper fluid level.
Replace the oil filler cap and dipstick. (press the dipstick
into place and turn clockwise until finger-tight.)
Run the engine, shutdown and recheck the fluid level.
A
WARNING:
Never
pull
out
the
dipstick
while
the
engine
is
running.
Hot
fluid
will
splash
from
the
dipstick
hole.
This
could
cause
severe
burns.
Oil
Capacity
Approximately 2.5 quarts (2.36 liters) will fill most transmis-
sions to the oil level fill mark on the dipstick. Many variables
have a direct relationship to the oil capacity. Additional oil
will
be
required to fill the oil cooler and the cooler lines. The
angle
of
installation will make a difference in the quantity
of
oil required to fill the transmission.

Oil
Temperature
MAX
A maximum oil temperature
of
190
0
P (88°C) is recom-
mended. Discontinue
operation anytime sump oil tempera-
ture exceeds
230
0
P
(1

PRESSURE
GAUGE
An
optional mechanical pressure gauge can
be
installed at
the control panel to constantly monitor the pressure
of
the
transmission fluid. A normal reading at
2000 rpm in forward
gear should indicate 95 - 120 Ib-in
2
(6.7 - 8.4 kg-cm
2
)
and be
constant.
