My car has a minor shaking in front comes and goes usually between forty five to sixty mph. if I gas it or I brake or even coast it goes away, but at same time this is happening the speedometer jumps five to ten mph with no rpm movement. no check engine light and if i just keep steady it keeps doing it for a mile are two and goes away but will come back.

It is possible this could be coming from the trans-axle and although the check engine does not come on there may still be trouble codes being stored in the PCM and/or the TCM referring to this problem, so you should still have the trouble codes retrieved and try to have them retrieved from the TCM (transmission control module) as well as the PCM (power-train control module).
