I have a 95 150 with the 5.8 e40d. just wondering what might cause the trans to shift hard enough to basically shake the whole truck. i know the trans was rebuilt cause my dad had it done when he had the truck. just a simple question that i have.

 

Is it through every gear or perhaps just when putting it in gear? Check out your trans and engine mounts, u-joints and since its e4od scan your codes it might help you out. Also check your fluid condition
