Light red: pink
|
Contaminated with water

• Broken oil cooler inside of radiator
• Poor filler tube installation:
Problem could be occurring to parts inside the transaxle by water contamination. It is necessary to overhaul transaxle and detect defected parts. If necessary, exchange transaxle.

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 in oil pipe, control valve body and oil cooler in radiator.
• When large amount of metal specks are found, overhaul transaxle and detect defected parts. If necessary, exchange transaxle.
• Implement flushing operation as there is a possibility to have specks plugging up oil pipe and/or oil cooler inside of radiator.

Automatic Transaxle Fluid (ATF) Level Inspection
-
Caution
-
• The ATF amount varies according to ATF's 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 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 cool range.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 (D-L) 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.
