Hi all, my car is jerking heavily sometimes when let’s say driving out of a roundabout picking up speed from 3rd to 4th and 4th to 5th.Also let’s going through a town around 30-40 km/hr. No hassle taking off from stopped, idling, motorway etc. Automatic gearbox. Can’t get help or answers locally. Dunno what to do. All help graciously accepted. 🙏
