3.
Remove the reservoir lid (see
) and install
the pressure bleed adaptor on the reservoir.
4.
Bleed the hydraulic system as follows.
4.1
Open the bleed valve on the bleed tank
to pressurize the reservoir.
4.2
Remove the cap from the bleed valve of
the slave cylinder. See
. On the
valve, install a transparent drain hose
connected to a catch bottle. The hose
needs to fit the bleed valve tight enough
so it does not fall off when fluid is
pumped out.
4.3
Open the bleed valve on the slave cylin-
der.
4.4
When the draining fluid is clear and free
of air bubbles, close the bleed valve.
5.
Check the fluid level in the reservoir. If neces-
sary, add or drain fluid to bring the fluid level to
between the MIN and MAX lines marked on the
side of the reservoir.
6.
Install the reservoir lid.
7.
Disconnect the transparent hose. Tighten the
bleed screw 88 lbf·in (1000 N·cm) and install the
cap on the slave cylinder bleed valve.
8.
Depress the clutch pedal a few times. There
should be resistance over the full pedal stroke.
Manual Bleeding
1.
Park the vehicle on a level surface, shut down
the engine, and set the parking brake. Chock the
tires and open the hood.
NOTE: The hydraulic system holds approxi-
mately 0.5 quart (0.5 liter) of fluid. It may need
to be refilled during the bleeding process to pre-
vent air from re-entering the system.
2.
Remove the reservoir lid and fill the reservoir
(see
) with new DOT 4 brake fluid from a
tightly sealed container.
3.
Remove the cap from the bleed valve of the
slave cylinder. See
. On the valve, install a
transparent drain hose connected to a catch
bottle. The hose needs to fit the bleed valve tight
enough so it does not fall off when fluid is
pumped out.
NOTE: The following steps require two people—
one in the cab to work the clutch pedal, and one
to open and close the bleed valve and watch
the fluid.
4.
Bleed the system, as follows.
4.1
Open the bleed valve.
4.2
Depress the clutch pedal until it stops.
4.3
Close the bleed valve.
4.4
Return the pedal to the upper position.
4.5
Repeat the previous steps until the fluid is
clear and free of air bubbles.
4.6
Depress the clutch pedal. There should
be resistance over the full pedal stroke.
5.
Check the fluid level in the reservoir. If neces-
sary, add or drain fluid to bring the fluid level to
between the MIN and MAX lines marked on the
side of the reservoir. Install the reservoir lid.
6.
Disconnect the transparent hose. Tighten the
bleed valve 88 lbf·in (1000 N·cm) and install the
cap on the slave cylinder bleed valve.

26–00 Safety Precautions
Safety Precautions in this section apply to all
procedures within this group.
DANGER
When working on the vehicle, shut down the en-
gine, set the parking brake, and chock the tires.
Before working under the vehicle, always place
jack stands under the frame rails to ensure the
vehicle can not drop. Failure to follow these steps
could result in serious personal injury or death.

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.
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, then remove
it from the side of the gear case. Remove the
drain plug from the bottom of the case. See
.
3.
Clean the fill plug and the drain plug.
4.
Remove the oil pump screen and check it for
debris. See
. Clean the screen, if needed,
then install it with a new seal washer. Tighten the
plug 90 lbf·ft (120 N·m).
5.
Install a new seal on the drain plug, then install
the plug and tighten it 45 lbf·ft (60 N·m).

Detroit transmissions use synthetic lubricant that
meets the requirements of the MB 235.11 specifi-
