Your 2002 century doesn't have a timing belt. It has a timing chain. Timing chains don't need to be changed at a certain mileage.

My 2002 Buick Century is jerking when it shifts gears. It is a automatic. Why is it jetking when it shifts?


Jerky shifts with an automatic transmission is normally cause by the valvebody in your transmission sticking. You could try to change the transmission fluid and filter but I seriously doubt this will solve your problem. Please rate my answer.
