I have a car 2005 Toyota vitz. When I drive I feel a problem. When my acceleration is 20 then my Gear is Shifted and car give jerking, again when 40 then again shifted and jerking. But its very problem to drive. I want to know is there any solution to avoid this jerking. Is it my gear box problem. By the my gear box is CVTI gear box and its automatic gear

you are facing low transmission oil line pressure problem. it can be fixed by following methods after full diagnostic.

1:CVT Pressure calibration.
2: G sensor relearning

if the problem doesn't solve by uper mentioned procedure's then you need to perform valve body assy service to counter the jamming pistons movement in the valve body assy.
