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.

Fluid and Filter Change

When draining transmission fluid, check for evidence
of dirt or water contamination. A small amount of
condensation will appear in the fluid during operation.

Water contamination is normally characterized as a
milky discoloration of the transmission fluid. Obvious
contamination of the transmission fluid indicates a
leak between the water and fluid areas of the trans-
mission cooler. Inspect and pressure-test the cooler
to confirm the leak; replace leaking transmission
coolers.

1.

Drain the transmission when the fluid is warm. If
not already warm, run the engine until the trans-
mission reaches normal operating temperature:
160 to 200°F (71 to 93°C).

2.

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

3.

Clean the area around the drain plug and the
transmission fluid pan. Place a drain pan under
the transmission and remove the drain plug. Ex-
amine the fluid as it drains.

4.

Remove the 12 mounting bolts (six each) from
the two filter covers.

NOTE: A lot of fluid will drain when the filter
covers are removed.

5.

Remove the filter covers, O-rings, and two
square-cut seals from the transmission. See

Fig. 2

.

6.

Remove the filters from the bottom of the control
module.

7.

Lubricate the new O-rings with transmission fluid,
and install them on the cover assemblies.

8.

Install a new square-cut seal on each cover as-
sembly, and install the fluid filter elements on the
cover assemblies.

9.

Install the filter and cover assemblies into the
filter compartment.

10. Align each cover assembly with the holes in the

channel plate sump, and push the cover assem-
blies in by hand to seat the seals.

NOTICE

Do not use the bolts to draw the filter covers to
the sump. This can damage the covers, seals, or
sump.

11. Install six bolts in each cover, and torque the

bolts 38 to 44 lbf·ft (51 to 61 N·m).

12. Replace the drain plug O-ring, and install the

drain plug. Tighten the drain plug 18 to 24 lbf·ft
(25 to 32 N·m).

13. Refill the transmission with fresh automatic trans-

mission fluid and check the fluid level. See

Table 4

for transmission lubricant capacities, and

Table 5

for approved transmission lubricants.

1.

Apply the parking brakes and chock the rear
tires. Drain the air reservoirs.

WARNING

Drain the air supply; if the air supply is not
drained before the air filter/regulator is serviced,
serious injury and component damage could re-
sult.

2.

Clean the outside of the air filter/regulator with
cleaning solvent. See

Fig. 3

.

3.

Remove the end cap, large O-ring, and filter ele-
ment from the filter housing. See

Fig. 4

. Remove

the small O-ring from the end cap.

NOTE: Do not remove, disassemble, or adjust
the air regulator. If the air regulator is not keep-
ing the air pressure between 58 and 63 psi (400
to 435 kPa), replace the air filter/regulator. It
cannot be repaired.

WARNING

Wear safety goggles when using compressed air
to clean parts, as permanent harm to eyes could
result from flying debris.

4.

Clean the filter element by dipping it in alcohol or
other cleaning solvent. Blow compressed air
through the filter element (inside to outside) to
loosen surface dirt and to dry the element. If it is
not damaged, the sintered metallic filter element
will last the life of the vehicle.

Wipe out the filter housing with a clean, dry, lint-
free rag. Clean and inspect the O-rings and the
end cap. Replace any parts that are damaged.

5.

Install the large O-ring, then the filter element
(small end first) into the filter housing.

6.

Install the small O-ring in the end cap, then in-
stall the end cap and tighten it until firm.

NOTICE

A leaking air filter or air lines can cause slow or
hard shifting of the transmission, and eventual
transmission damage.

7.

Start the engine, and build pressure in the air
system. Check for air leaks at the filter housing
and air line connections; repair any leaks.

Meritor

NOTE: This procedure does not apply to
FreedomLine transmissions.

1.

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

2.

Remove the element from the air filter/regulator
assembly. Inspect the O-rings in the end cap;
replace worn or damaged O-rings. Inspect the
element for fluid contamination. If fluid is present,
replace the element. Inspect the air supply sys-
tem for the source of the fluid, and service it as
needed.

3.

Install the element in the filter/regulator assem-
bly.

4.

Apply a light coat of silicone grease, or an
equivalent grease to the O-rings in the end cap.
Install and tighten the end cap 10 to 15 lbf·ft (14
to 20 N·m).

5.

Build air pressure in the system, check for leaks,
and make any needed repairs.
