7. Add new transmission fluid (DIAMOND ATF SP III) through

the oil filter tube.

Approximately 3.5 dm

3

(3.7 quarts) of transmission

fluid should be added.

NOTE: Check for contamination or a burnt odor. If the trans-
mission fluid is still contaminated or burnt, repeat Steps 6
and 7 before proceeding to Step 8.

8. Reconnect the hose which was disconnected in step 1

above, and firmly replace the dipstick.

9. Start the engine and run it at idle for one to two minutes.
10.Move the selector lever through all positions, and then move

it to the "N" position.

11.Check that the transmission fluid level is at the "COLD"

mark on the dipstick. If the level is less than this, add
transmission fluid.

12.Drive the vehicle until the transmission fluid temperature

rises to the normal operating temperature [70

− 80°C (158 −

176

°F)], and then check the transmission fluid level again.

The transmission fluid level must be at the "HOT" mark.
NOTE: The transmission fluid temperature is measured with
scan tool MB991958 (MUT-III sub assembly).
NOTE: The "COLD" level is for reference only; the "HOT"
level should be regarded as the standard level.
NOTE: If it takes some amount of time until the transmission
fluid reaches its normal operating temperature [70

−

80

°

C

(158

−

176

°

F)], check the transmission fluid level by refer-

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

M1231013000347

Required Special Tool:
MB995062: Flushing Tool

WARNING

•

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

−

1968 and OSHA. Wear stan-

dard 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 transaxle failure has contaminated the transmission
fluid, the oil cooler(s) must be flushed. The cooler by-pass
valve in the transaxle must also be replaced. The torque con-
verter 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)
transaxle. There are two different procedures for flushing cool-
ers and lines. The recommended procedure is to use special
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 transaxle 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 transaxle.

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

5. Connect the pressure line to the OUTLET line (from cooler).
6. Connect the return line to the INLET line (to cooler).
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 suction line from the reservoir at the cover

plate. Disconnect the 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 suction line into a one quart container of

DIAMOND ATF SP III or equivalent 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 transaxle 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

M1231013100214

After the new or repaired transaxle has been installed, fill to the
proper level with DIAMOND ATF SP III. 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 transaxle may occur.
1. Disconnect the OUTLET line (from cooler) at the transaxle

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 transaxle to the proper level, using DIAMOND
ATF SP III.
