CAUTION

Stop pouring if the full volume of A/T fluid cannot be
poured in.
5. Pour new A/T fluid in through the oil filter tube.

Adding volume: Approximately 5.5 dm

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

contaminated A/T fluid)

7. Pour the new A/T fluid in through the oil filler tube.

Adding volume: Approximately 3.5 dm

(3.7 quarts)

NOTE: Check the A/T fluid for contamination or burnt smell.
If 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 A/T fluid level is at the "COLD" mark on the

dipstick. If the level is lower than this, pour in more A/T fluid.

12.Drive the vehicle until the A/T fluid temperature rises to the

normal temperature [70

check the A/T fluid level again. The A/T fluid level must be at
the "HOT" mark.

NOTE: The A/T fluid temperature is measured with scan tool
(MUT-II).

NOTE: The "COLD" level is for reference only; the "HOT"
level should be regarded as the standard level.

FLUSHING COOLERS AND TUBES

M1231013000046

Required Special Tool:
MB995062: Flushing Tool

WARNING

•

Wear protective eye wear that meets the
requirements of OSHA and ANSI Z87.1

−−−−

1968.

Wear standard 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
ventilated. Do not let flushing solvent come in
contact with water for 15 to 20 seconds. Remove
contaminated clothing and wash affected skin with
soap and water. Seek medical attention.

When a transaxle failure has contaminated the A/T fluid, the oil
cooler(s) must be flushed. The cooler by-pass valve in the
transaxle must also be replaced. The torque converter must
also be replaced with an exchange unit. This will ensure that
metal particles or sludged A/T fluid are not later transferred
back into the reconditioned (or replaced) transaxle. There are
two different procedures for flushing coolers and lines. The
recommended procedure is to use Tool MB995062 Cooler
Flusher. 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 of 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 filler plug on special tool MB995062.

3. Verify 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 BLUE pressure line to the OUTLET (From)

cooler line.

6. Connect the CLEAR return line to the INLET (To) cooler line.

7. Turn the pump "ON" for two to three minutes to flush the

cooler(s) and lines. Monitor pressure readings and 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.

8. Turn the pump "OFF."

9. Disconnect the CLEAR suction line from the reservoir at

cover plate. Disconnect the CLEAR 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 and lines. Turn the pump "OFF."

11.Place the CLEAR suction line into a one quart container of

DIAMOND ATF SP III, ATF SP II M or equivalent A/T fluid.

12.Turn the pump "ON" until all A/T fluid is removed from the

one quart container and lines. This purges any residual
cleaning solvent from the transaxle cooler 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

M1231013100043

After the new or repaired transaxle has been installed, fill to the
proper level with DIAMOND ATF SP III, ATF SP II M or
equivalent A/T fluid. The flow should be checked using the
following procedure:

CAUTION

With the fluid set at the proper level, A/T fluid collection
should not exceed one quart or internal damage to the
transaxle may occur.
1. Disconnect the OUTLET (From) cooler line 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 A/T fluid flow is intermittent or it takes more than 20

seconds to collect one quart of A/T fluid, replace the cooler.

4. If flow is found to be within acceptable limits, reconnect the

cooler line. Then fill the transaxle to the proper level, using
the approved type of A/T fluid.
