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
