Salam everyone ,
i own a grande 2017 with 50k on odo , I got its cvt gear oil change and poured original toyota CVT oil (large gray tin) FE
2000kms ago. (Chamber opened and all work done as suggested by professionals on pw)
car performed well in 1000km drive but
Its been a while i am noticing jerks when i drive on light foot. These jerks are only noticeable between 0-20 speed i.e only during first gear shift provided that its driven on light foot. Similarly, releasing the foot from acceleration pedal also give a light jerk. If i drive on heavy foot , then there are less jerks or if i switch off eco mode , They jerks reduces.
The speed decreases quickly and give a light jerk when i release acceleration pedal while driving or braking at slow speeds
Any professional with cvt please help , i have read Alot on internet , Also got hands on Techstream now and have got all readings of Sensors but cant figure out the problem and issue with it.
After 1 hour of drive - Outside temp 16°C - Cvt fluid temp reading is - 210F And pressure on P gear is 1.5mpa approx.
Also did cvt calibrations but the car still does the problem.
About the fuel system have already done all , Cleaned injectors changed plugs engine oil and well tuned throttle body its all set. But after searching Alot found that cvt is the culprit. No check engine light or codes.
