there are trans shop that will give you free check
cottman is one. other charge $85.00 . you might have a bad trans or engine mount broken and the engine is jumping up and down causing a jerk. you should cv joints looked at if they have play this will cause a pause and jerk . all these checks are easy to do most shops will check these free
