26–01 Manual Transmission

Fluid Level Checking

1.

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

2.

With the transmission at operating temperature
(Eaton Fuller transmissions) or at room tempera-
ture (Meritor transmissions), check the oil level in
the transmission.

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

.

3.

If needed, fill the transmission with oil until level
with the lower edge of the fill opening.

See

Table 1

for approved lubricants.

CAUTION

Operating a manual transmission with the oil level
higher or lower than recommended can result in
transmission damage. Do not overfill the transmis-
sion; overfilling will force oil out of the case
through the main shaft openings. Oil overflow
may also drain onto the clutch or clutch brake,
causing additional problems.

IMPORTANT: Do not mix types of oil, because
of possible incompatibility. Do not use oil addi-
tives or friction modifiers. Do not use multi-
viscosity oils or EP (Extreme Pressure) gear
oils. If switching from a petroleum based lubri-
cant to a synthetic, all areas of each affected

component must be thoroughly drained. Switch-
ing 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 from a petroleum-based lubricant.

4.

Clean the fill plug, then install it in the gear case.
Tighten the plug as follows:

Transmission Fluid
Changing and Magnetic
Plug Cleaning

Draining

1.

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

2.

Drain the oil while the transmission is warm.

3.

Clean the area around the fill plug and the drain
plug(s).

4.

Remove the fill plug from the side of the gear
case. Remove the drain plug(s) from the bottom
of the case.

5.

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

6.

Install and tighten the drain plug(s) 50 lbf·ft (68
N·m) for an Eaton Fuller plug and 35 to 50 lbf·ft
(48 to 67 N·m) for a Meritor plug.

NOTE: Meritor recommends replacing the mag-
netic drain plug each time the oil is changed.

Filling

1.

Add oil until it is level with the lower edge of the
fill opening. See

Fig. 1

. If the transmission has

two fill openings, add oil to the level of both fill
openings.

See

Table 1

for approved transmission lubri-

cants. See

Eaton Fuller transmissions. See
