The vehicle body vibration occurs when starting due to deterioration of the transmission oil and wear of the clutch disc.
Improvement measures
１, Meshing adjustment of the CVT starter clutch
１ Press the brake firmly and fully open the accelerator pedal in D range for 3 seconds.
２ Rotate for about 20 seconds at 3000 rpm in N range
３ Press the brake firmly and fully open the accelerator pedal in D range for 3 seconds.
４ Rotate for about 20 seconds at 3000 rpm in N range
５ Firmly press the brake and fully open the accelerator pedal for 3 seconds in the R range.
６ Rotate for about 20 seconds at 3000 rpm in N range
２, Drain the CVT oil and transmission oil.
- Drain until oil stops dripping.
３, There is sludge on the drain bolt, so remove it completely.
４, Replace with new HMMF
５, Hold the shift lever for at least 3 seconds in each range in order to circulate oil through all ranges.
６, Repeat steps 1 to 5 again.
７, Let the CVT completely cool down
８, Start the engine and warm it up
９, Learn the operation of the start clutch.
– Increase the vehicle speed to 60km/h with no load and release the accelerator for more than 5 seconds.
Do this about 5 times
１０, Check the oil level again with the oil level gauge on a flat place.
If the judder does not improve after performing the above steps, CVT replacement is required.
Automotive maintenance cannot determine the cause based on symptoms alone.
Be sure to perform diagnosis and inspection before determining the cause of the failure.
