As for your noise, I bet you have a shift kit and/or hard shift bushings installed.
My SYMS shifter made a grinding/vibration noise when decelerating. The noise can be best described as sounding gritty. Put the stock shifter back in and the noise went away. So if it's your shifter, that goes under (Manual Trans). If it's not a stock component problem, don't vote!
Ok, it it's not the shifter, then the provided thread points to the Trans components so it still would go under (Manul Trans)....
