Level Inspection
NOTICE
Operating a transmission with the fluid level
higher or lower than recommended can result in
transmission damage. Do not overfill the transmis-
sion. Overfilling will force fluid out of the case
through the main shaft openings.
Do not mix types or brands of fluid, because of
possible incompatibility. Do not use fluid addi-
tives, friction modifiers, or extreme-pressure gear
fluids.
With the transmission at operating temperature, and
the vehicle on a level surface, check the fluid level in
the transmission.
1.
Clean the area around the fill plug, then remove
it from the side of the gear case.
2.
Using your finger or a bent pipe cleaner, see if
the fluid is level with the fill opening. See
.
3.
If the fluid level is low, check the transmission for
leaks, and correct as needed.
NOTICE
Detroit transmissions use synthetic lubricant that
meets the requirements of the MB 235.11 specifi-
cation, such as Detroit Synth 75W-90. Using lubri-
cant that does not comply with this specification
will result in damage to the transmission. The oil
part number can be found in module 348 in
PartsPro.
4.
If needed, add the recommended fluid until it is
level with the lower edge of the fill opening. See
for approved transmission lubricants.
5.
Clean the fill plug and install a new seal on it.
Install the plug in the side of the gear case, then
tighten it 45 lbf·ft (60 N·m).

the engine, and set the parking brake. Chock the
tires.
2.
Drain the main air system and the isolated trans-
mission reserve air tank. See
.
3.
Remove the air filter canister, located between
the main air system and the transmission reserve
air tank. See
.
4.
Remove and discard the air filter.
5.
Install a new air filter.
6.
Install the air filter canister.
7.

sion. Overfilling will force fluid out of the case
through the main shaft openings.
Do not mix types or brands of fluid, because of
possible incompatibility. Do not use fluid addi-
tives, friction modifiers, extreme-pressure gear
fluids, or multiviscosity lubricants.
IMPORTANT: Drain the transmission when the
fluid is warm. If not already warm, run the en-
gine until the transmission fluid reaches operat-
ing temperature. Shift the transmission to neu-
tral (N) and shut down the engine.
1.
Apply the parking brakes, and chock the rear
tires. Place a large drain pan under the transmis-
sion.
2.
Clean the area around the fill plug, and remove it
from the side of the gear case. Remove each
drain plug from the bottom of the case.
3.
Clean the fill and drain plugs. For magnetic
plugs, use a piece of key stock or any other con-
venient steel slug to short the two magnetic
poles and divert the magnetic field.
4.
Install each drain plug and tighten them 50 lbf·ft
(68 N·m).
NOTE: For an Eaton Fuller transmission, the
optional transmission fluid filter is a remote-
mount, spin-on type, and is located between the
transmission and the fluid cooler. The filter
bracket is attached to the frame rail or some
other nearby location. The filter is mounted in a
vertical position, and should be filled with fluid
before installation to assure the proper fluid
level. For optimum transmission performance,
change the filter each time that the fluid is
changed.
5.
For an Eaton Fuller transmission equipped with a
transmission fluid filter(s), replace the fluid fil-
ter(s) as follows:
5.1
Place a drain pan under the transmission
fluid filter.
CAUTION
To prevent skin burns from hot transmission fluid,
wear protective gloves when removing the filter.
5.2
Place a strap or chain wrench around the
filter canister, and rotate it in a counter-
clockwise motion to separate the filter
from the mounting. Carefully spin the filter
off the mount and remove it from the ve-
hicle.
5.3
Apply a light coat of transmission fluid to
the O-ring gasket on the new filter. Fill the
filter with specified transmission fluid, and
spin the filter onto the mount.
NOTE: The filter fills slowly, so be patient to
ensure the proper fluid level has been set.
5.4
Once the filter makes contact with the
mount, use a strap wrench to rotate the
canister an additional 180 to 270 degrees
to firmly tighten the filter. Wipe the filter
clean of any fluid after it is tightened.
6.
Add fluid until it is level with the lower edge of
the fill opening. See
. If the transmission
has two fill openings, add fluid to the level of
both openings. See
for approved trans-
mission lubricants, and
for transmission
lubricant capacities.

7.
Operate the engine for five minutes after filling
the transmission, then check the fluid level again.
8.
Clean the fill plug, then install it in the transmis-
sion. Tighten the plug as follows:
• For an Eaton Fuller transmission with a
plug with 3/4-inch pipe threads, tighten the
plug 25 to 35 lbf·ft (34 to 48 N·m).
• For an Eaton Fuller transmission with a
plug with 1-1/4-inch pipe threads, tighten
the plug 60 to 75 lbf·ft (81 to 102 N·m).
9.
Operate the vehicle to check for correct opera-
tion.

Level Inspection
NOTICE
Operating a transmission with the fluid level
higher or lower than recommended can result in
transmission damage. Do not overfill the transmis-
sion. Overfilling will force fluid out of the case
through the main shaft openings.
Do not mix types or brands of fluid, because of
possible incompatibility. Do not use fluid addi-
tives, friction modifiers, extreme-pressure gear
fluids, or multiviscosity lubricants.
With the transmission at operating temperature, and
the vehicle on a level surface, check the fluid level in
the transmission.
Some transmissions are equipped with a sight glass
for checking the fluid level. For transmissions not so
equipped, check the fluid level at the fill plug.
Checking at the Fill Plug
1.
Clean the area around the fill plug, and remove it
from the side of the gear case.
2.
Using your finger or a bent pipe cleaner, see if
the fluid is level with the fill opening. See
.
3.
If the fluid level is low, check the transmission for
leaks, and correct as needed.
4.
If needed, add the recommended fluid, until it is
level with the lower edge of the fill opening. See
for approved transmission lubricants.

as follows:
• For an Eaton Fuller transmission with a
plug with 3/4-inch pipe threads, tighten the
