Is it an easy or moderate task to replace the tranny mount in a 2002 ZX5? I am pretty sure that is what the noise is coming from. If I reverse then put it in first and pull away I can feel a thud and it makes a slight thud. It I am in first or second and I let off and coast then reapply the gas it does the same thing only harder. is it the tranny mount or is it something else? If it is, is it easy to change? Is it something I will have to take to the dealer? If not, where can I find a guide to help me? I am not afraid to do it on my own...
