PROCEDURE

REPLACE CONTINUOUSLY VARIABLE TRANSAXLE FLUID
1. Lift the vehicle. [*1]
  
  Note
  
  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 of the vehicle is within +/-1°).
2. Remove the No. 1 engine under cover.

4. Remove the refill plug and gasket from the continuously variable transaxle assembly. [*2]
5. Using a 10 mm hexagon socket wrench, remove the drain plug and gasket from the transaxle oil (CVT) pan sub-assembly. [*3]
6. Measure the amount of fluid drained. [*4]
  
  Tech Tips
  
  Add the same amount of fluid in step [*6].
7. Using a 10 mm hexagon socket wrench, temporarily install the gasket and drain plug to the transaxle oil (CVT) pan sub-assembly. [*5]
  
  Tech Tips
  
  Reuse the old gasket as the drain plug will be removed again when flushing the CVT fluid.
8. Add fluid to the refill hole using the same amount of fluid drained in step [*4]. [*6]
  
  Note
  
  Use Toyota Genuine CVT fluid FE.
9. Temporarily install the gasket and refill plug to the continuously variable transaxle assembly. [*7]
  
  Tech Tips
  
  Reuse the old gasket as the refill plug will be removed again when flushing the CVT fluid.
10. Lower the vehicle. [*8]
11. Start the engine. [*9]
12. 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). [*10]
  
  Tech Tips
  
  Slowly move the shift lever to circulate the fluid through each part of the continuously variable transaxle assembly.
13. Allow the engine assembly to idle for 30 seconds to warm it up. [*11]
14. Turn the ignition switch off. [*12]
15. Repeat steps [*1] to [*12].
16. Repeat steps [*1] to [*12].
17. Using a 10 mm hexagon socket wrench, install a new gasket and the drain plug to the transaxle oil (CVT) pan sub-assembly.
