I recently went to Toyota to get a diagnostic done. Everything came back normal but it’s still jerking when I press on the gas. I don’t know what it could be :(. This is my first car and I’m at a loss right now

The MMT gearshift of my Toyota Yaris 2005 with 115000km is very jerky, especially from standstill to reverse/1°. Could be depending on the gearshift parameters which do not match the geometries of the gearshift anymore?
Thanks!

At the maximum left or right turn while the car is moving backwards, it sounds as if the wheel is spinning normally and suddenly jerkily, as if you are stepping over a obstacle with the wheel. I changed the anti-roll bars because both had broken rubber, but the problem was not solved.
