Automatic Transaxle Fluid (ATF) Condition Inspection

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


ATF Condition

Possible cause

Clear red

Normal

Light red: pink

Contaminated with water

  • Broken oil cooler

  • 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.

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 in oil hose, control valve body and oil cooler.

    • 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 hose and/or oil cooler.

Has no burnt smell

Normal

  • Discoloration by oxidation


Automatic Transaxle Fluid (ATF) Level Inspection

CAUTION:

NOTE:

1. Inspect the ATF level before driving the vehicle.

a. Park the vehicle on level ground, and then engage the parking brake and use wheel chocks at the front and rear of the wheels.

b. Verify visually that there is no ATF leakage from the oil hose or housing.

c. Start the engine and warm it up in the P position.

CAUTION:

d. Remove the dipstick and wipe it clean while the engine is idling.

e. Install the dipstick and remove it again.

f. Verify that the ATF level is in the range as shown in the figure.


2. Inspect the ATF level after driving the vehicle.

a. Shift the selector lever and pause momentarily in each position (from the P position to the D position) while depressing the brake pedal.

b. Drive on city roads at a minimum of 5 km {3 mile}.

c. Connect the M-MDS to the DLC-2.


d. Verify that the ATF temperature is 60—70 °C {140—158 °F} using the M-MDS.

e. Remove the dipstick and wipe it clean while the engine is idling.

f. Verify that the ATF level is in the range as shown in the figure.
