Ok, I have a 98GT and I have been slowly noticing that then engine has been rocking more and more whenever I very lightly give it gas and and then very lightly let off the gas. It's kinda like a bucking motion. Is this the tranny mount? and how do you tell if its bad(cracks)? any help would be appreciated, thanks. I am thinking of replacing them with ENERGY SUSPENSION polyurethane motor mounts and trany mount. Is this the right way to go?
