I've got a 02 gt 5 speed and had 3.73's put in. needless to say, they are not in correct. Is there in one in ohio who would be willing to help me out fixing them? i've never worked on gears. They are "whining" at low speeds decelerating, and rumbling above 70 when decelerating. I live in Zanesville.

any tips/contacts would be appreciated!

thanks
