PROCEDURE


  1. PRECAUTIONS AND WORK DESCRIPTION


    1. The K115 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.

      Tech Tips

      "Overflow" indicates the condition under which fluid comes out of the overflow plug hole.

    2. 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.

    3. The K115 continuously variable transaxle assembly requires Toyota Genuine CVT Fluid FE.

    4. 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°).

    5. 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.

    6. The fluid temperature in the text indicates "A/T Oil Temperature 1" displayed on the GTS.

    7. Fluid level adjustment should be performed according to the following procedure and notes.
