The car has very serious issues with the transmission. when driving it jerks violently when switching gears from 2nd to 3rd gear and some times to the 4th gear. the dashboard some times shows the car has switched to the 3rd gear while the car is still revving abnormally high in 2nd gear. the transmission has some very serious and potentially deadly issues. this issues tend to occur frequently when accelerating from a stop. (the car's acceleration is very weak, i don't know if this is related to the issue or not )
