based lubricant.

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.

Eaton Fuller Procision

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.

With the engine running at idle, remove the dip-
stick from the tube and wipe it clean.

Insert the dipstick into the tube, then remove it.

Check the fluid level reading, then repeat the
check procedure to verify the reading.

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

Table 3

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.

Park the vehicle on a flat, level surface.

Apply the parking brakes and chock the rear
tires.

Run the engine for at least one minute.

Shift from DRIVE to NEUTRAL, and then shift to
REVERSE to fill the hydraulic system.

Shift to NEUTRAL and allow the engine to idle at
500 to 800 rpm.

With the engine running at idle, remove the dip-
stick from the tube and wipe it clean.

Insert the dipstick into the tube, then remove the
dipstick.

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.

NOTICE

Do not fill above the COLD RUN band if the trans-
mission fluid is below normal operating tempera-
ture. As fluid temperature increases, so does the
fluid level. Filling above the COLD RUN band
when the transmission is below normal operating
temperature may result in an overfilled transmis-
sion, which causes fluid foaming and aeration.
Fluid foaming and aeration cause transmission
overheating and erratic shifting.

NOTE: Perform a hot check at the first opportu-
nity after the normal operating temperature, 160
to 200°F (71 to 93°C) has been reached.

Hot Check

Park the vehicle on a flat, level surface. Apply
the parking brakes and chock the rear tires.

Shift the transmission to NEUTRAL.

Operate the engine at idle (500 to 800 rpm) until
normal operating temperature is reached. Check
that the sump temperature is 160 to 200°F (71 to
93°C). Check that the converter-out temperature
is 180 to 220°F (82 to 104°C).

With the engine idling, remove the dipstick from
the tube and wipe it clean.

Insert the dipstick into the tube, then remove it.

Check the fluid level reading and repeat the
check procedure to verify the reading. Safe oper-
ating level is within the HOT RUN band on the
dipstick. The HOT RUN band is between the
HOT FULL and HOT ADD marks.

If the fluid level is not within the HOT RUN band,
add or drain fluid as needed to bring the fluid
level within the HOT RUN band. See

Fig. 2

approved Allison transmission lubricants, see

Mercedes-Benz

Park the vehicle on a level surface. Apply the
parking brakes and chock the rear tires.

Check the oil level in the transmission as follows.

2.1

Clean the area around the fill plug, then
remove the plug from the side of the
case.

2.2

Using your finger or a bent pipe cleaner,
see if the oil is level with the lower edge
of the fill opening. See

Fig. 1

If needed, fill the transmission with oil until level
with the lower edge of the fill opening. For ap-
proved lubricants, see

cants for its transmissions on its internet website.

Draining

IMPORTANT: Manual transmissions filled with
approved synthetic lubricants require a lubricant
drain and fill, and a magnetic plug cleaning
every 500,000 miles (800 000 km), regardless
of the service or vocation of the vehicle. Manual
transmissions with petroleum-based lubricants
require a lubricant drain and fill, and a magnetic
plug cleaning at each Maintenance 2 (M2) inter-
val. All transmissions, regardless of lubrication
used, also require a check of the transmission
breather at each Maintenance 1 (M1) interval.

Park the vehicle on a level surface. Apply the
parking brakes and chock the rear tires.

Drain the fluid while the transmission is warm, as
follows.

2.1

Clean the area around the drain plug(s).
Remove the drain plug(s) from the gear
case.

2.2

Clean the area around the fill plug or the
dipstick tube. Remove the fill plug from
the gear case, if applicable.

Clean the magnetic plug(s) before installing it.
Use a piece of key stock, or any other conve-
nient steel slug, to short the two magnetic poles
and divert the magnetic field.

Install and tighten the drain plug(s) 50 lbf·ft (68
N·m).

For Procision transmissions, change the lubrica-
tion filter as follows:

NOTICE

To prevent damage to the threads, use hand tools
to remove the lubrication filter housing. When in-
stalling the housing, hand-tighten it prior to final
torque.

5.1

Remove the lubrication filter housing from
the clutch housing.

5.2

Remove the lubrication filter cartridge and
the lubrication filter housing O-ring.

5.3

Install a new lubrication filter cartridge.

5.4

Install a new lubrication filter housing
O-ring, and lubricate it with an approved
lubricant; see

Table 3

5.5

Hand-tighten the lubrication filter housing,
then torque it 20 to 24 lbf·ft (27 to 32
N·m).

Filling

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. Fluid overflow
may also drain onto the clutch or clutch brake,
causing additional problems.

IMPORTANT: Do not mix types of fluid, because
of possible incompatibility. Do not use multi-
viscosity fluids or EP (Extreme Pressure) gear
fluids. Do not use fluid additives or friction modi-
fiers. If switching from a petroleum-based lubri-
cant to a synthetic lubricant, all areas of each
affected component must be thoroughly drained.
Switching to a synthetic lubricant, when a
petroleum-based lubricant has been used for
50,000 miles (80 000 km) or longer may affect
transmission performance. Monitor all seal
areas for the first 10,000 miles (16 000 km)
after changing to a synthetic lubricant from a
petroleum-based lubricant.

NOTE: The correct fluid level is established by
checking at the fill plug opening (manual and
automated) or the oil level dipstick (Procision).

On manual and automated transmssions, add
fluid until it is level with the lower edge of the fill
opening. See

Fig. 1

. If the transmission has two

fill openings, add fluid to the level of both fill
openings. See

Table 1

for approved transmission

lubricants. See

Table 6

for lubricant capacities.

On Procision transmssions, add fluid through the
transmission oil dipstick tube, until the level is
within the COLD range, as marked on the dip-
stick. See

Table 3

for approved transmission lu-

bricants. See

Table 6

for lubricant capacities.

Check and adjust the fluid level using the appli-
cable Eaton Transmission fluid level checking
procedure in

MOP 26–01

Clean the fill plug (if applicable), then install it in
the transmission. 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.

Transmission Breather
Checking

Transmission housing breathers (if equipped) must
remain clear. A plugged breather could result in pres-
sure build-up, which could cause oil leakage.

If the breather is plugged, clean or replace it. See

. Check more often if the vehicle is operating

under very dusty conditions.
