AUTOMATIC TRANSAXLE FLUID (ATF) INSPECTION [LA4A-EL]
ATF Condition Inspection

1. If the ATF is muddy or varnished.
2. If the ATF smells strange or unusual.





ATF Condition

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 of the thermistor probe measure to the same length as the dipstick and hold the probe with a paper holder. Insert into the filler tube and measure the temperature.
4. Warm up the engine until the ATF reaches 66 - 77° C (150 - 170° F).

Caution Do not warm the transaxle by performing stalls. This will damage the torque converter.

5. While depressing the brake pedal, shift the selector lever to each range (P-1), pausing momentarily in each range.
6. Shift back to P position.





Note If the ATF level is too high or too low in hot condition, the cause of the following problems are shown above.





7. Ensure that the ATF level is between max. and min.
