7. Drive the vehicle in 6GR, 5GR, 4GR and 3GR and verify that kickdown occurs for 6

→5, 5→4, 4→3, 3→2

downshifts, and that the shift points are as shown in the table below.

AUTOMATIC TRANSAXLE FLUID (ATF) INSPECTION[AW6A-EL, AW6AX-EL]

id051723800500

Automatic Transaxle Fluid (ATF) Condition Inspection

1. Inspect the ATF for the following to determine whether the transaxle should be disassembled.

• The ATF is muddy.

• The ATF smells strange or unusual.

ATF Condition

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 and adjust the ATF amount to
the specified level according to the specified temperature.

1. Place the vehicle on level ground.
2. Apply the parking brake and position wheel chocks securely to prevent the vehicle from rolling.

Condition

Possible cause

Clear dark red

Normal

—

Light red (pink)

Contaminated with water

• Damaged oil cooler

• Poor filler tube installation:

Problem could occur to parts inside the transaxle due
to water contamination.
If necessary, replace the transaxle.

Reddish
brown

Has burnt smell and metal
particles are found

Deteriorated ATF

Defective powertrain components inside the transaxle:
Particles cause wide range of problems by clogging
the oil pipe, control valve body and oil cooler.

• A large amount of metal particles are found.

If necessary, replace the transaxle.

• Flush the system due to possible clogging of the oil

pipe or oil cooler.

Has no burnt smell

Normal

• Discoloration by oxidation

3. Adjust the length or thermometer probe so that

the length is the same as the depth gauge, and
hold the probe with a paper holder. Insert into the
filler tube and measure the temperature.

• If necessary, inspect the ATF before warming

up the engine. In this case, use the ATF
temperature (15— 25

°C {59— 77 °F}).

4. Warm up the engine until the ATF reaches 60—

70

°C {140— 158 °F}.

5. Shift the selector lever and pause momentarily in

each range (P— D) while depressing the brake
pedal.

6. Shift the selector lever to P position.
7. Verify that the ATF level is in the HOT range (65

°C {149 °F}) while the engine is idling.

• If necessary, add ATF to the specification.
