Inspection

INFOID:0000000009177643

FLUID LEAKAGE

• Check transaxle surrounding area (oil seal and plug etc.)for fluid

leakage.

• If anything is found, repair or replace damaged parts and adjust

CVT fluid level. Refer to

TM-187, "Adjustment"

.

Replacement

INFOID:0000000009177644

CAUTION:

• Always use shop paper. Never use shop cloth.

• Replace a drain plug gasket with new ones at the final stage of the operation when installing.

• Use caution when looking into the drain hole as there is a risk of dripping fluid entering the eye.

• After replacement, always perform CVT fluid leakage check.
1. Select “Data Monitor” in “TRANSMISSION” using CONSULT.
2. Select “FLUID TEMP” and confirm that the CVT fluid temperature is 40

°C (104°F) or less.

3. Check that the selector lever is in the “P” position, then completely engage the parking brake.
4. Lift up the vehicle.
5. Remove the drain plug and drain the CVT fluid from the oil pan. Refer to

TM-197, "Exploded View"

.

6. Install the drain plug to oil pan.

CAUTION:

Drain plug gasket use the old one.

7. Remove the overflow plug from converter housing.

9. Install the ATF changer hose (B) to the charging pipe.

CAUTION:

Press the ATF changer hose all the way onto the charging

pipe until it stops.

10. Fill approximately 3 liter (3-1/8 US qt, 2-5/8 lmp qt) of the CVT

fluid.

11. Remove the ATF changer hose and charging pipe, then install

the overflow plug.

NOTE:

Perform this work quickly because CVT fluid leaks.

12. Lift down the vehicle.
13. Start the engine.
14. While depressing the brake pedal, shift the selector lever to the entire position from “P” to “L”, and shift it

to the “P” position.

NOTE:

Hold the lever at each position for 5 seconds.

15. Check that the CONSULT “Data Monitor” in “FLUID TEMP” is 35

°C (95°F) to 45°C (113°F).

16. Stop the engine.
17. Lift up the vehicle.
18. Remove the drain plug, and then drain CVT fluid from oil pan.
19. Repeat steps 8 to 18 (one time).
20. Tighten the drain plug to the specified torque. Refer to

TM-197, "Exploded View"

.

21. Remove the overflow plug.
22. Install the charging pipe set (KV311039S0) into the overflow plug hole.

CAUTION:

Tighten the charging pipe by hand.

23. Install the ATF changer hose to the charging pipe.

CAUTION:

Press the ATF changer hose all the way onto the charging pipe until it stops.

24. Fill approximately 3 liter (3-1/8 US qt, 2-5/8 lmp qt) of the CVT fluid.

NOTE:

Perform this work quickly because CVT fluid leaks.

26. Lift down the vehicle.
27. Start the engine.
28. While depressing the brake pedal, shift the selector lever to the entire position from “P” to “L”, and shift it

to the “P” position.

NOTE:

Hold the lever at each position for 5 seconds.

29. Check that the CONSULT “Data Monitor” in “FLUID TEMP” is 35

°C (95°F) to 45°C (113°F).

30. Lift up the vehicle.
31. Remove the overflow plug and confirm that the CVT fluid is drained from the overflow plug hole.

CAUTION:

Perform this work with the vehicle idling.

NOTE:

If the CVT fluid is not drained, refer to “Adjustment” and refill with the CVT fluid.

32. When the flow of CVT fluid slows to a drip, tighten the overflow plug to the specified torque. Refer to
