If you have a transmission fluid changer, use this changer to
replace the transmission fluid. If you do not have a transmission
fluid changer, replace the transmission fluid by the following
procedure.

Transmission fluid cooler
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.
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 dm3(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 dm3(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 (23 ± 2 ft-lb)
Stop pouring if the full volume of transmission fluid can not
be added.
5.Add new transmission fluid (DIA QUEEN ATF J-2) through the
oil filter tube.
Approximately 5.5 dm3(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 J-2) through the
oil filter tube.
Approximately 3.5 dm3(3.7 quarts) of transmission
fluid should be added.
NOTE: Check for contamination or a burnt odor. If the
transmission 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 referring 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.
