AUTOMATIC TRANSAXLE FLUID (ATF) INSPECTION

A3U051719001W01

Automatic Transaxle Fluid (ATF) Condition Inspection

1. One way of determining whether the transaxle should be replaced is by noting:

•

If the ATF is muddy or varnished.

•

If the ATF smells strange or unusual.

ATF condition

Condition

Possible cause

Clear red

Normal

—

Light red (pink)

Contaminated with water

•

Broken oil cooler inside of radiator

•

Poor filler tube installation:

Problem could be occurring to parts inside of transaxle
by water contamination.

•

If necessary, replace transaxle.

Reddish
brown

Has burnt smell and metal
specks are found

Deteriorated ATF

Defect powertrain components inside of transaxle:
Specks cause wide range of problems by plugging up
oil pipe, control valve body and oil cooler in radiator.

•

When large amount of metal specks are found.
Replace transaxle if necessary.

•

Implement flushing operation as there is a
possibility to have specks plugging up oil pipe and/
or oil cooler inside of radiator.

Has no burnt smell

Normal

•

Discoloration by oxidation.

Automatic Transaxle Fluid (ATF) Level Inspection

Caution

••••

The ATF amount varies according to ATF temperature. Therefore, when checking the ATF level or
replacing the ATF, use a thermometer to measure the temperature then adjust the ATF amount to
the specified level according to the specified temperature.

1. Park the vehicle on level ground.
2. Apply the parking brake and position wheel chocks securely to prevent the vehicle from rolling.
3. Adjust the length or thermistor probe to measure the same depth as the oil dipstick and hold the probe with a

paper holder.

4. Insert into the filler tube and measure the

temperature.

5. Inspect the ATF level before warming up the

engine. In this case, use the cool (20

°°°°

C {68

°°°°

F})

range.

6. Warm up the engine until the ATF reaches (60—

70

°°°°

C {141—158

°°°°

F}).

7. While depressing the brake pedal, shift the

selector lever to each range (P—1), pausing
momentarily in each range.

8. Shift back to P position.
9. While the engine is idling, verify that the ATF level

is in the HOT (65

°°°°

C {149

°°°°

F}) range. Add ATF to

the specification, if necessary.

ATF type

M-V or equivalent (e.g. Dexron

Warning

••••

When the transaxle and ATF are hot, they can badly burn you. Turn off the engine and wait until
they are cool before changing the ATF.

1. Remove the oil dipstick.
2. Remove the drain plug and washer.
3. Drain the ATF into a container.
4. Install a new washer and the drain plug.

Tightening torque

30—41 N·m {3.0—4.2 kgf·m, 22—30 ft·lbf}

5. Add the specified type of ATF through the oil filler

tube until ATF level reaches lower notch of
dipstick.

ATF type

M-V or equivalent (e.g. Dexron

®

III)

6. That the ATF level is in the HOT (65

°°°°

C {149

°°°°

F}) range.

7. Add ATF to the specified level if necessary.
