Freightliner FLA/FLB/FLC/FLD/FLL. Manual - part 16

Remove the filters from the bottom of the control
module.

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

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

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.

CAUTION

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 Dexron

transmission fluid and check the fluid level.

NOTE: Do not overfill the transmission. Follow

Oil Changing, and Oil
Filter Element Changing

Manual Transmission Oil
Changing

IMPORTANT: For all transmissions that are filled
with approved synthetic lubricants, the lubricant
must be changed every 500,000 miles (800 000
km). Transmissions with petroleum-based lubri-
cants must have the lubricant changed at each
Maintenance 2 (M2) interval. All transmissions
with synthetic or petroleum-based lubricants
must have the transmission breather checked
and the magnetic plugs cleaned at each M1
interval.

NOTE: For vehicles equipped with auxiliary
transmissions, use this procedure to change the
auxiliary transmission oil and to check the auxil-
iary transmission breather whenever changing
the main transmission oil and checking the main
transmission breather.

With the vehicle parked on level ground, apply
the parking brakes, and chock the tires. Place a
large drain pan under the transmission.

Clean the area around the fill plug, and remove it
from the side of the case. Remove each drain
plug from the bottom of the transmission case.
Drain the oil while the transmission is warm.

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.

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

Transmission housing breathers must remain
clear. A plugged breather could result in pressure
build-up, which could cause oil leakage. If the
breather is plugged, clean or replace it. See

. Check more often if the vehicle operates

under very dusty conditions.

NOTE: For a Fuller transmission equipped with
an oil filter(s), change the filter as instructed
under "Fuller Transmission Oil Filter Element
Changing", before filling the transmission with
oil.

IMPORTANT: Do not mix types and brands of
oil, because of possible incompatibility. Do not
use oil additives, friction modifiers, extreme-
pressure gear oils, or multiviscosity lubricants.
Do not use extreme-pressure additives, such as
those found in multipurpose or rear-axle-type
lubricants. These additives are not required, and
may create transmission problems. Multipurpose
oils have relatively poor oxidation stability, a
high rate of sludge formation, and a greater ten-
dency to react on or corrode steel and bronze
parts.

NOTE: The correct oil capacity is established by
the fill opening.

Add oil until it is level with the lower edge of the
fill opening. If the transmission has two fill open-
ings, add oil to the level of both openings. See

Fig. 8

. See

Table 1

for transmission lubricant

capacities, and see

Table 2

for approved trans-

mission lubricants.

CAUTION

Operating a Fuller or Spicer transmission with the
oil level higher or lower than recommended can
result in transmission damage. Do not overfill the
transmission. On Fuller transmissions, overfilling
will force oil out of the case through the main
shaft openings. On Spicer transmissions, overfill-
ing usually causes oil breakdown, due to exces-
sive heat and aeration from the churning action of
the gears. Early breakdown of the oil causes
heavy varnish and sludge deposits that plug oil
ports and build up on splines and bearings. Oil
overflow may also drain onto the clutch or clutch
brake, causing additional problems.

For a transmission equipped with an oil pump or
an oil cooler, operate the engine for five minutes
after filling the transmission, then check the oil
level again.

Install the fill plug, then tighten it 50 lbf·ft (68
N·m).

Operate the vehicle to check for correct
operation.
