areas for the first 10,000 miles (16 000 km)
after changing to a synthetic from a petroleum-
based lubricant.
4.
Clean the fill plug, then install it in the transmis-
sion. Tighten the plug as follows:
•
25 to 35 lbf·ft (34 to 48 N·m) for Eaton
Fuller transmissions with 3/4-inch pipe
threads.
•
60 to 75 lbf·ft (81 to 102 N·m) for Eaton
Fuller transmissions with 1-1/4-inch pipe
threads.

1.
Park the vehicle on a level surface. If equipped
with a shift lever, select PARK. If equipped with a
push button shift control, select NEUTRAL. Apply
the parking brakes and chock the rear tires.
2.
With the engine running at idle, remove the dip-
stick from the tube and wipe it clean.
3.
Insert the dipstick into the tube, then remove it.
4.
Check the fluid level reading, then repeat the
check procedure to verify the reading.
5.
Add or drain transmission fluid if the level is not
within the HOT or COLD range (depending on
the transmission oil temperature), as marked on
the dipstick. Add oil through the transmission oil
dipstick tube. For approved lubricants, see

Cold Check
Clean all dirt away from around the end of the fluid
fill tube before removing the dipstick.
NOTICE
Do not allow foreign matter to enter the transmis-
sion. Dirt or foreign matter in the hydraulic system
may cause undue wear of transmission parts,
make valves stick, and clog passages.
It is important to check the fluid level cold to deter-
mine if the transmission has a sufficient amount of
fluid to be safely operated until a hot check can be
performed.
1.
Park the vehicle on a flat, level surface.
2.
Apply the parking brakes and chock the rear
tires.
3.
Run the engine for at least one minute.
4.
Shift from DRIVE to NEUTRAL, and then shift to
REVERSE to fill the hydraulic system.
5.
Shift to NEUTRAL and allow the engine to idle at
500 to 800 rpm.
6.
With the engine running at idle, remove the dip-
stick from the tube and wipe it clean.
7.
Insert the dipstick into the tube, then remove the
dipstick.
8.
Check the fluid level reading and repeat the
check procedure to verify the reading.
If the fluid level is within the COLD RUN band,
the transmission may be operated until the fluid
is hot enough to perform a HOT RUN check.
If the fluid level is not within the COLD RUN
band, add or drain fluid as needed to adjust the
fluid level to the middle of the COLD RUN band.
