Good morning,

Is the check engine light on?

Does the transmission seem to be working properly?

No check engine light on but I think transmission is fine. The car just starts jerking after half an hour and I don't know what's wrong with it.

I would suspect a clogged catalytic converter. I would have this checked as it would give you all those symptoms.
