PROCEDURE

Hide 3.REPLACE CONTINUOUSLY VARIABLE TRANSAXLE FLUID

a.

Lift the vehicle. [#1]

NOTICE:

Set the vehicle on a lift so that the vehicle is kept level when it is lifted up (make sure that the tilt angle from the front to rear and side to side of the vehicle is within +/- 1°).



b.
C437662

Remove the refill plug and gasket from the rear transaxle case sub-assembly. [#2]


c.
C394993

Using a 10 mm hexagon socket wrench, remove the overflow plug and gasket from the transaxle case sub-assembly and drain the fluid. [#3]


d.
C394994C01

*1 Overflow (CVT) Tube


Using a 6 mm hexagon socket wrench, remove the overflow (CVT) tube from the transaxle case sub-assembly and drain the fluid. [#4]


e.
C394995

Measure the amount of fluid drained. [#5]

HINT:

Add the same amount of fluid in step [#8].



f.
C394994C01
2.375,0.844 2.656,0.844 true 2.219,0.771 2.448,1 0.229,0.229 10 false *1
*1 Overflow (CVT) Tube


Using a 6 mm hexagon socket wrench, install the overflow (CVT) tube to the transaxle case sub-assembly. [#6]

Torque:
0.8 N*m (8 kgf*cm, 7 in.*lbf)


g.
C394993

Using a 10 mm hexagon socket wrench, temporarily install the overflow plug and gasket to the transaxle case sub-assembly. [#7]

HINT:

Reuse the old gasket as the overflow plug will be removed again to adjust the fluid level.



h.
C437664

Add fluid to the refill plug hole using the same amount of fluid drained in step [#5]. [#8]

NOTICE:

Use Toyota Genuine CVT fluid FE.

Using CVT (Continuously Variable Transaxle) fluid other than the above type may cause abnormal noise or vibration, or damage the CVT (Continuously Variable Transaxle) of the vehicle.



i.
C437662

Temporarily install the refill plug and gasket to the rear transaxle case sub-assembly. [#9]

HINT:

Reuse the old gasket as the refill plug will be removed again to adjust the fluid level.



j.

Lower the vehicle. [#10]


k.

Start the engine. [#11]


l.

Slowly move the shift lever from P to D, and then back to P (keep the shift lever in each position for approximately 3 seconds). [#12]

HINT:

Slowly move the shift lever to circulate the fluid through each part of the continuously variable transaxle assembly.



m.

Allow the engine assembly to idle for 30 seconds to warm it up. [#13]


n.

Turn the ignition switch off. [#14]


o.

Repeat steps [#1] to [#14].


p.

Repeat steps [#1] to [#10].


Hide 8.PERFORM ATF THERMAL DEGRADATION ESTIMATE RESET

NOTICE:

If approximately 50% or more of the CVT fluid has been replaced during a repair of the transaxle or a similar operation, perform ATF Thermal Degradation Estimate Reset.
