NOTE: If it takes some amount of time until the transmission
fluid reaches its normal operating temperature [70

−

°

(158

ring to the left diagram.

13.When the transmission fluid is less than the specified level,

add transmission fluid.
When the transmission fluid is greater than the specified
level, drain the excess fluid through the drain plug to adjust
the transmission fluid to the specified level.

14.Firmly insert the dipstick into the oil filler tube.

FLUSHING COOLERS AND TUBES

Required Special Tool:

• MB995062: Flushing Tool

WARNING

•

Wear protective eyewear that meets the require-
ments of and ANSI Z87.1

−

1968 and OSHA. Wear

standard industrial rubber gloves.

•

Keep lighted cigarettes, sparks, flames, and other
ignition sources away from the area to prevent the
ignition of combustible liquids and gases. Keep a
class B fire extinguisher in the area where the
flushing tool will be used. Keep the area well venti-
lated. Do not let flushing solvent come in contact
with eyes or skin. If it does, flush with water for 15
to 20 seconds. Remove contaminated clothing and
wash affected skin with soap and water. Seek med-
ical attention.

When a transmission failure has contaminated the transmission
fluid, the oil cooler(s) must be flushed. The cooler by-pass
valve in the transmission must also be replaced. The torque
converter must also be replaced with an exchange unit. This
will ensure that metal particles or sludged transmission fluid are
not later transferred back into the reconditioned (or replaced)
transmission. There are two different procedures for flushing
coolers and lines. The recommended procedure is to use spe-
cial tool MB995062 Flushing Tool. The other procedure is to
use a hand suction gun and mineral spirits.
1. Remove the cover plate filler plug on special tool

MB995062. Fill the reservoir 1/2 to 3/4 full with fresh flushing
solution. Flushing solvents are petroleum based solutions
generally used to clean transmission components. Do not
use solvents containing acids, water, gasoline, or any other
corrosive liquids.

2. Reinstall the filler plug on special tool MB995062.
3. Verify that the pump power switch is turned "OFF." Connect

the red alligator clip to the positive battery terminal. Connect
the black alligator clip to a good ground.

4. Disconnect the cooler lines at the transmission.

NOTE: When flushing the transmission cooler and lines,
always reverse flush.

5. Connect the BLUE pressure line to the OUTLET line (from

cooler.) cooler line.

6. Connect the CLEAR return line to the INLET line (to cooler.)

cooler line.

7. Turn the pump "ON" for two to three minutes to flush the

cooler(s) and lines. Monitor the pressure readings. Clear the
return lines. Pressure readings should stabilize below 138
kPa (20 psi) for vehicles equipped with a single cooler and
208 kPa (30 psi) for vehicles equipped with dual coolers. If
flow is intermittent or exceeds these pressures, replace the
cooler(s).

8. Turn the pump "OFF."
9. Disconnect the CLEAR suction line from the reservoir at the

cover plate. Disconnect the CLEAR return line at the cover
plate, and place it in a drain pan.

10.Turn the pump "ON" for 30 seconds to purge flushing

solution from the cooler(s) and lines. Turn the pump "OFF."

11.Place the CLEAR suction line into a one quart container of

DIAMOND ATF SP III transmission fluid.

12.Turn the pump "ON" until all transmission fluid is removed

from the one quart container and lines. This purges any
residual cleaning solvent from the transmission cooler(s)
and lines. Turn the pump "OFF."

13.Disconnect the alligator clips from the battery. Reconnect

the flusher lines to the cover plate, and remove the flushing
adapters from the cooler lines. Reconnect the cooler lines.

OIL COOLER FLOW CHECK

M1231104900167

After the new or repaired transmission has been installed, fill to
the proper level with DIAMOND ATF SP III transmission fluid.
The flow should be checked using the following procedure:

CAUTION

With the fluid set at the proper level, transmission fluid
collection should not exceed one quart or internal damage
to the transmission may occur.
1. Disconnect the OUTLET line (from cooler) at the

transmission and place a collecting container under the
disconnected line.

2. Run the engine at curb idle speed with the shift selector in

neutral.

3. If transmission fluid flow is intermittent or it takes more than

20 seconds to collect one quart of transmission fluid, replace
the cooler.

4. If flow is within acceptable limits, reconnect the cooler line.

Then fill the transmission to the proper level, using
DIAMOND ATF SP III transmission fluid.

M1231109700146

Required Special Tool:

• MB991958: Scan Tool (MUT-III Sub Assembly)

• MB991824: V.C.I.

• MB991827: MUT-III USB Cable

• MB991911: MUT-III Main Harness B

1. Set the selector lever to the "N" position.
2. Loosen the control cable to manual control lever coupling

nut to free the cable and lever.

3. Set the manual control lever to the neutral position.
4. Loosen the transmission range switch body mounting bolts

and turn the transmission range switch body so the hole in
the end of the manual control lever and the hole (cross
section A

− A in the figure on the left) in the flange of the

transmission range switch body flange are aligned.
NOTE: The transmission range switch body can be aligned
by inserting a 5-mm diameter steel bar into the end hole of
the manual control lever and the flange hole of the transmis-
sion range switch body.

5. Tighten the transmission range switch body mounting bolts

to the specified torque. Be careful at this time that the switch
body does not move.

Tightening torque: 10

− 12 N⋅m (89 − 106 in-lb)

6. Gently pull the transmission control cable in the direction of

the arrow, until the cable is taut. Tighten the adjusting nut.

Tightening torque: 24 N

⋅m (18 ft-lb)

7. Check that the selector lever is in the "N" position.
8. Check that each position of the manual control lever

matches each position of the selector lever using scan tool
MB991958.
