every time i go in the highway,my van starts shaking.....i go over 40 it runs smooth...its coming from my engine i think.what could it be? my other question is....i can get under my van and shake my transmission..i can move it side to side..is it suppose to move like that or is it suppose to stay in place? what do i do about that?
