6. Securely insert the dipstick.

NOTE: The transmission fluid should always be replaced 
under the following conditions:

.

•

When troubleshooting the transaxle.

•

When overhauling the transaxle.

•

When the transmission fluid is noticeably dirty or burnt 
(driving under severe conditions).

TRANSMISSION FLUID CHANGE

If you have an transmission fluid changer, use this changer to 
replace the transmission fluid. If you do not have an 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: 32 

± 2 N⋅m (24 ± 1 ft-lb)

CAUTION

Stop pouring if the full volume of transmission fluid can 
not be added.
5. Add new transmission fluid (DIAMOND ATF SP III) 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 (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.

13. ENGINE COOLANT (CHANGE)

M1001003100357

Check the cooling system parts such as the radiator, heater 
and oil cooler hoses, thermostat and their connections for leak-
age and damage.

.

Changing Coolant
1. Set the temperature control knob to the "HOT" position.
2. Run the engine until the engine coolant warms, and then 

stop the engine.

WARNING

When removing the radiator cap, use care to avoid 
contact with hot coolant or steam. Place a shop towel 
over the cap and turn the cap counterclockwise a lit-
tle to let the pressure escape through the vinyl tube. 
After relieving the steam pressure, remove the cap by 
slowly turning it counterclockwise.

3. Drain the water from the radiator, heater core and engine 

after unplugging the radiator drain plug and removing the 
radiator cap.

4. Drain the water in the water jacket by unplugging the drain 

plug of the cylinder block.

5. Remove the radiator condenser tank assembly and drain the 

coolant.

6. Drain the coolant then clean the path of the coolant by 

injecting water into the radiator from the radiator cap area.

7. Apply the designated sealant to the screw area of the 

cylinder block drain plug, and then tighten to the standard 
torque.
