TRANSMISSION FLUID CHANGE

M1231021500187

If you have a transmission fluid changer, use this changer to
replace the transmission fluid. If you do not have a transmis-
sion fluid changer, replace the transmission fluid by the follow-
ing procedure.
1. Disconnect the hose shown in the illustration which

connects the transaxle and the oil cooler (inside the
radiator). Place a container under the hose to collect the
discharge.

CAUTION

The engine should be stopped within one minute after it is
started. If all the transmission fluid has drained out before
then, the engine should be stopped at that point.
2. Start the engine and let the transmission fluid drain out.

(Running conditions: "N" range with engine idling)

Approximately 3.5 dm

3

(3.7 quarts) of transmission

fluid should be removed.

3. Remove the drain plug from the bottom of the transaxle case

to drain the transmission fluid.

Approximately 2.0 dm

3

(2.1 quarts) of transmission

fluid should be removed.

4. Install the drain plug with a new gasket, and tighten it to the

specified torque.

Tightening torque: 7.4

± 2.4 N⋅m (65 ± 21 in-lb)

CAUTION

Stop pouring if the full volume of transmission fluid cannot
be added.
5. Add new transmission fluid (DIA QUEEN ATF- J3) through

the oil filter tube.

Approximately 5.5 dm

3

(5.8 quarts) of transmission

fluid should be added.

6. Repeat the procedure in Step 2. (to pump out the rest of the

contaminated transmission fluid)

7. Add new transmission fluid (DIA QUEEN ATF- J3) 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 insert 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 "C" 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 "H" mark.
NOTE: The transmission fluid temperature is measured with
scan tool MB991958 (M.U.T.-III sub assembly).
NOTE: The "C" level is for reference only; the "H" 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.

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) tran-
saxle. There are two different procedures for flushing coolers
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 DIA

QUEEN ATF- J3 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

M1231013100300

After the new or repaired transaxle has been installed, fill to the
proper level with DIA QUEEN ATF- J3. 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 DIA QUEEN
ATF- J3
