ADJUSTMENT
PROCEDURE
1. PRECAUTIONS AND WORK DESCRIPTION
(a) The K114 continuously variable transaxle assembly does not have an oil filler tube or oil level gauge. When adding fluid, add fluid through the refill hole in the continuously variable transaxle assembly. The fluid level can be adjusted by draining excess fluid (allowing excess fluid to overflow) through the No. 1 transmission oil filler tube of the transaxle oil (CVT) pan sub-assembly.
HINT:
"Overflow" indicates the condition under which fluid comes out of the overflow plug hole.
(b) When adding fluid, add the specified amount of fluid while the engine assembly is cold. Then, warm up the engine assembly to circulate the fluid in the continuously variable transaxle assembly and adjust the fluid level with the engine idling at the specified fluid temperature.
(c) The K114 continuously variable transaxle assembly requires Toyota Genuine CVT fluid FE.
(d) When adjusting the fluid level, park the vehicle on level ground (make sure that the tilt angle from the front to rear of the vehicle is within +/-1°).
(e) When adjusting the fluid level, turn off all electrical systems, such as the air conditioning, lighting system, electric fan and audio system, to reduce load.
(f) The fluid temperature in the text indicates "A/T Oil Temperature 1" displayed on the Techstream.
(g) Fluid level adjustment should be performed according to the following procedure and notes.
2. WORK FLOW
(a) The adjustment should be performed according to the procedures referenced in the work flow below.
3. BEFORE FILLING TRANSAXLE WITH FLUID
NOTICE:
If the continuously variable transaxle assembly is hot (fluid temperature is high), wait until the fluid temperature becomes the same as the ambient temperature before starting the following procedure (recommended fluid temperature: approximately 20°C (68°F)).
(a) Lift the vehicle.
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 of the vehicle is within +/-1°).
(b) Remove the No. 1 engine under cover.

4. PERFORM INITIAL FILLING
NOTICE:
After performing either of the following operations, it is not necessary to perform the initial filling procedure. Proceed to Add Specified Amount of Fluid (Step 5).
Operations that do not Require Initial Filling |
---|
|
(a) Remove the refill plug and gasket from the continuously variable transaxle assembly. |
|
(b) Using a 6 mm hexagon socket wrench, remove the overflow plug and gasket from the transaxle oil (CVT) pan sub-assembly. NOTICE:
|
|
(c) Using a 6 mm hexagon socket wrench, check that the No. 1 transmission oil filler tube is tightened to the specified torque. Torque: 1.7 N·m {17 kgf·cm, 15 in·lbf} NOTICE: If the No. 1 transmission oil filler tube is not tightened to the specified torque, the amount of fluid cannot be precisely adjusted. HINT: To check the torque of the No. 1 transmission oil filler tube, insert a 6 mm hexagon socket wrench into the overflow plug hole. |

HINT:
Slowly move the shift lever to circulate the fluid through each part of the continuously variable transaxle assembly.
(i) While observing the D shift indicator on the combination meter, move the shift lever back and forth between N and D at an interval of less than 1.5 seconds for 6 seconds or more. NOTICE: Do not pause for 1.5 seconds or more. HINT: Performing this operation will cause the vehicle to enter fluid temperature detection mode. |

8. ADJUST FLUID LEVEL
CAUTION:
Use caution, as the fluid is hot while the engine is idling and the radiator fan is operating.
(a) Lift the vehicle.
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 of the vehicle is within +/-1°).
(b) Using a 6 mm hexagon socket wrench, remove the overflow plug and gasket from the transaxle oil (CVT) pan sub-assembly. CAUTION: Be careful as the fluid coming out of the overflow plug hole is hot. |
|
(c) Check the amount of fluid that comes out of the overflow plug hole.
NOTICE:
If only a small amount of fluid (approximately 5 cc (0.3 cu. in.)) comes out of the overflow plug hole, then only fluid remaining in the No. 1 transmission oil filler tube has come out. This is not considered to be overflow.
(d) *1: If the amount of fluid that comes out of the overflow plug hole is large, wait until the fluid flow slows and only drips come out. HINT: The fluid flow will not stop completely because the fluid continues to expand as its temperature increases. |
|
(e) *2: If no fluid comes out of the overflow plug hole, remove the refill plug and gasket. Then add fluid through the refill hole until fluid comes out of the overflow plug hole. Wait until the fluid flow slows and only drips come out. NOTICE: Use Toyota Genuine CVT fluid FE. |
|
(f) Using a 6 mm hexagon socket wrench, install a new gasket and the overflow plug to the transaxle oil (CVT) pan sub-assembly. Torque: 40 N·m {408 kgf·cm, 30 ft·lbf} |
|
(g) Install a new gasket and the refill plug to the continuously variable transaxle assembly. Torque: 49 N·m {500 kgf·cm, 36 ft·lbf} |
|
(h) Lower the vehicle.
(i) Turn the ignition switch off.
HINT:
Turning the ignition switch off exits fluid temperature detection mode.
